1) The document discusses the coevolution of technology, cognition, culture, and organizations in humans over millions of years, from tool-using savanna apes to today's socio-technical organizations.
2) Around 5 million years ago, climate change forced forest-dwelling apes out of East Africa, selecting for increased brain capacity and cultural adaptation on the savanna. Tool use and social cooperation allowed hunting and scavenging of large prey.
3) By 3-2 million years ago, hominins' competitive scavenging and hunting reduced other carnivore populations in East Africa, establishing hominins as top carnivores. The spread of tool-using hominins like Homo erect
Discussing the emergence of formal knowledge management systems in prehistoryWilliam Hall
Reviews Dr Lynne Kelly's new and revolutionary understanding of the roles of Neolithic monuments such as Stonehenge, Gobekli Tepe and Poverty Point in managing the large increases in knowledge cultures required to make the transition from mobile hunting and gathering to settled farming and urban life.
Dr Kelly's book "Knowledge and Power in Prehistoric Societies - Orality, Memory, and the Transmission of Culture", explains how the mnemonic technology known as the method of loci, as implemented in monumental architecture, helped people to index, rehearse, preserve and share large bodies of technical and customary survival knowledge knowledge in living memory. She also shows how the method of loci can be used in conjunction with portable devices to index large bodies of personal knowledge.
Mobile hunters and gathers are known to index their knowledge-laden stories against prominent features along traditional paths they follow through landscapes they traverse. Aboriginal Australians call these paths "song-lines". As hunters and gatherers became more sedentary they no longer had ready access to their traditional song-lines and devised more compact artificial landscapes they could use to order and rehearse the growing bodies of knowledge they needed to manage the complexities of urban life and agriculture.
Kelly's ideas are likely to revolutionize our understanding of prehistoric archaeology and anthropology.
Monkey Business — What apes and New World monkeys tell us about the origins o...William Hall
This document discusses how apes and New World monkeys can provide insights into the origins of human culture, technology, and knowledge management. It suggests that:
1) Environmental pressures like climate change forced early hominins out of forests onto the savanna, requiring new adaptations like cooperative hunting and tool use to survive.
2) Chimpanzees and bonobos demonstrate intelligent tool use and social cooperation, suggesting our last common ancestor had similar capacities.
3) Capuchin monkeys in some environments independently evolved sophisticated nut-cracking industries using stone hammers and anvils, showing convergent cognitive evolution.
4) Capuchins' problem-solving abilities and cultural transmission of tool
Episode 5(4): Apes become human with fire and language - Meetup session 19William Hall
The document discusses how early hominins like Homo erectus became human by controlling fire and developing language. It explores how using fire for cooking allowed for increased brain size and how maintaining fires required cognitive abilities like planning and cooperation. Early sites show evidence of fire use dating back 1.5 million years. The development of language around 150,000-200,000 years ago allowed for sharing knowledge culturally rather than just genetically. This helped drive further technological and cultural evolution in humans.
This document discusses the role of paleoanthropology in understanding the evolution of culture. It argues that while culture is a central concept in anthropology, paleoanthropology can provide important insights into how culture emerged and evolved over time in human ancestors. The document examines how stone tool technology can be used as an archaeological record to map cultural evolution among hominin species and gain insights into their cultural capacities. It also considers what paleobiological evidence may be found that correlates with different components of culture, such as learning, social organization, and symbolic expression.
This document summarizes research on primates and their use of tools. It begins by defining primates and noting their close relation to humans. It then discusses the historical view that only humans used and made tools, whereas now it is recognized that both apes and humans can use and make simple tools. While apes demonstrate an ability to modify their environment, they lack a material culture of tool transmission seen in humans. Possible reasons for this difference are explored, such as anatomical limitations or inability to imitate, but these are dismissed. The document suggests the key difference is humans' capacity for conceptual thinking, symbolic behavior, and cumulative learning that allows progressive development of tool usage over generations.
Episode 5(5): Mnemonics and the rise of social complexity - Meetup session 20William Hall
This is the 20th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
It is probable that the rise of social complexity in the development of agricultural and industrial economies required a major revolution in the social capacity to accumulate and manage the transmission of "working" (i.e., technical) knowledge. There is interesting evidence assembled by the Australian science writer, Lynne Kelly, that this revolution was based initially on a technology (defined as the practical application of knowledge especially in a particular area) based (1) on the construction and use of monumental theaters of the mind for effectively indexing objects of knowledge in living memory and (2) the practice within or around those theaters of particular social rituals for the accurate learning, maintenance, and transfer of those memory objects. This technology enabled initiates to store, manage, and accurately propagate a body of knowledge orders of magnitude larger than could be maintained by uninitiated.
For several thousands of years before the invention of counting tokens and symbolic and alphabetic scripts enabled knowledge to be objectified and stored by durable objects, such mnemonic technologies supported the emergence and maintenance of complex agricultural economies and specialized industries involved in the establishment of city states and state religions.
This session explains the circumstances of the Agricultural Revolution in the Neolithic and how mnemonic technologies extended the geospacial indexing and navigating capabilities that seem to be basic functions in the mammalian brain.
Archaeologists study human behavior through the analysis of material remains, while antiquarians are more interested in collecting artifacts for their beauty or value. Key differences include archaeologists being affiliated with scientific study and analysis, while antiquarians have more of a personal interest without a scientific focus. The document discusses the importance of context in archaeology and defines context as the physical location and circumstances of an artifact's discovery. It also provides definitions for many important terms in archaeology, anthropology, and the study of human evolution, including the differences between archaeologists and antiquarians, the archaeological record, and characteristics of early hominins.

The mouth and teeth play an important role in social interactions around the world. The way people deal with their teeth and mouth, however, is determined culturally. When oral healthcare projects are being carried out in developing countries, differing cultural worldviews can cause misunderstandings between oral healthcare providers and their patients. The oral healthcare volunteer often has to try to understand the local assumptions about teeth and oral hygiene first, before he or she can bring about a change of behaviour, increase therapy compliance and make the oral healthcare project sustainable. Anthropology can be helpful in this respect. In 2014, in a pilot project commissioned by the Dutch Dental Care Foundation, in which oral healthcare was provided in combination with anthropological research, an oral healthcare project in Kwale (Kenia) was evaluated. The study identified 6 primary themes that indicate the most important factors influencing the oral health of school children in Kwale. Research into the local culture by oral healthcare providers would appear to be an important prerequisite to meaningful work in developing countries.
This document outlines a guided discovery project on DNA, traits, and adaptability focusing on dinosaurs. It discusses using dinosaur DNA from blood found in amber to examine their traits and how those traits helped or hindered their ability to compete in their environment. Students will predict outcomes from crossbreeding dinosaurs and explain factors influencing the adaptability and survival of modern species. The project aims to develop students' understanding of evolution, genetics, and environmental interactions through hands-on skills like creating Punnett squares, spreadsheets, and presentations. Challenges include keeping student work practical and balanced while avoiding teacher over-assistance.
Human evolution began with the last common ancestor of all life and led to the emergence of modern humans. Key events included the divergence of primates from other mammals 85 million years ago, the evolution of bipedalism in hominins like Australopithecus 2-4 million years ago, and the appearance of Homo habilis and use of stone tools around 2.3 million years ago. Continued brain size increases in Homo erectus and archaic Homo sapiens were followed by anatomically modern humans evolving in Africa around 200,000 years ago. Genetic and fossil evidence from sites in Africa provide details on the major transitions that resulted in modern humans.
Animal domestication in geographic perspective kay andersonFábio Coltro
This document discusses perspectives on animal domestication from a geographic and cultural perspective. It summarizes the work of earlier scholars like Shaler and Sauer who viewed domestication as a cultural advance driven by human rationality and agency that separated humans from animals and led to civilization. However, more recent scholars have challenged this view, arguing that factors like fragile human ecosystems and mutual relationships between humans and animals also drove domestication. The document examines debates around the origins and causes of domestication and whether it was primarily a cultural or ecological phenomenon.
I. Beginning around 10,000 years ago, the Neolithic Revolution led to the development of new and more complex economic and social systems as some human groups adopted agriculture while others remained hunter-gatherers. Agricultural villages emerged in different regions, and pastoralism developed in parts of Africa and Eurasia. These changes drastically impacted environments.
II. Agriculture and pastoralism began to transform human societies, leading to more reliable food supplies, population growth, the development of elites and social hierarchies, and technological innovations in areas like pottery, plows, textiles, and metallurgy.
III. From around 5,000 years ago, urban societies developed, laying the foundations for early civilizations in regions like
Episode 5(2): Genomics, our African genesis and family tree - Meetup session 17William Hall
This is the 17th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
The growing fossil record and detailed genomic evidence provides an increasingly detailed understanding of our ancestry and genealogy.
Fossils and lost tools recovered from the geological record give us hints as to what kinds of humans were present in particular geographic areas. Various forms of dating based on the decay rates of a variety of different radioactive elements together with geology and stratigraphy tell us when they were there. This record grows more detailed through time as more paleoanthropologists study more areas in more detail and as Moore's law speeds up the publication cycle.
Enabled by the application of Moore's law to automated gene sequencing technology, over the last 5 years the detail and volume of genomic evidence has doubled and redoubled several times over. We can now compare the exact sequence of nucleotides in every single gene in the entire genomes of individual people, apes, and even some of our extinct cousins who lived 50,000 years or more ago, and do this down to differences in single nucleotides (i.e., to identify single character differences between two texts that are about 3 billions of characters long - about 1.5 million pages of text). Comparing the genomes of these ancient deceased relatives tells us a lot about what happened as long as half a million years or more in the past.
From these kinds of evidence we now know a great deal more about our genealogical relationships than we did five years ago.
Bare-bones summaries of current research papers relating to the Paleolithic in Franco-Iberia. Basic data, graphics and links only. News items to be fleshed out on the 2015 tour. Part 2 addresses new finds of fossils and artifacts and the interpretation of archaeological materials, including reports on the complex cultural activities of Neandertals. News items are presented in prehistoric chronological order.
The study examined language acquisition in two pygmy chimpanzees (Kanzi and Mulika) over 17 months using a lexigram communication system. Results showed Kanzi and Mulika learned and used lexigrams more spontaneously than previous common chimpanzee subjects. Kanzi demonstrated understanding of spoken English and use of multi-symbol combinations. Formal testing found Kanzi and Mulika performed significantly better than the common chimpanzees at matching lexigrams, photos and spoken words. The researchers concluded language learning may not require innate skills and can occur through cultural learning alone.
This document discusses the evolution of religion and the role of early priests in prehistoric human societies. It describes how as humans developed language and the ability to share experiences, they began to imagine unseen divine powers to explain natural phenomena they could not understand. Priests emerged as leaders who were responsible for rituals like burials of the dead and sacrifices to appease these imagined gods. Evidence from archaeological sites indicates priests played important roles in prehistoric communities as healers, teachers, and guides.
This document summarizes theories of human evolution from early hominids to modern humans. It discusses that:
- Bipedalism first emerged in hominids 4-1 million years ago, allowing use of hands and adaptation to grassland environments. Early tools date to 2.5 million years ago.
- Brain size increased over time, reaching 1000cc in Homo erectus and 1350cc in modern humans. This facilitated tool use, language, and other cognitive abilities.
- Two competing theories for modern human origins are presented - the multiregional hypothesis of evolving in multiple regions from Homo erectus, versus the recent "Out of Africa" hypothesis of descending from a single African
1) The document outlines key discoveries and ideas that challenged traditional biblical beliefs about creation and species fixity, including evidence of extinction, anatomical similarities between organisms, and changing organisms over time.
2) It discusses influential figures like Lyell, Lamarck, and Malthus and how their work related to ideas of deep time, adaptation, and limits on population growth.
3) Darwin's voyage on the Beagle and observations of related finch species in the Galapagos informed his later theory of natural selection and idea that species change over generations in response to their environment.
This document provides an introduction to cultural anthropology by outlining its four main subfields and objectives. It discusses how anthropology takes a holistic and comparative approach to studying humanity. The four subfields are cultural anthropology, archaeology, biological anthropology, and linguistic anthropology. Cultural anthropology examines human diversity and societies of the present and recent past through ethnographic fieldwork and ethnological comparison.
This document provides a syllabus for the NTA UGC NET JRF exam in Anthropology. It outlines 6 units that will be covered in the exam: 1) History and research methods in anthropology, 2) Primatology and hominid evolution, 3) Human variation and genetics, 4) Human growth and demography, 5) Archaeological concepts and methods, and 6) Lower Paleolithic cultures of India. Each unit provides detailed subtopics to be examined, such as primate taxonomy, fossil evidence for human evolution, archaeological dating techniques, and models of human variation.
The document summarizes key aspects of human evolution, including that Homo erectus were early tool users and fire users. It describes hominids as any bipedal, tool-using human species and notes there have been over a dozen hominid species. Lucy, a 3.2 million year old Australopithecus afarensis fossil, provided evidence that early hominids were bipedal. Even older footprints from 3.6 million years ago also showed bipedalism. Anatomically modern humans emerged around 195,000 years ago in Africa and then migrated throughout the world, with evidence suggesting all modern humans descend from a single female in Africa.
The story of the naked apes: What makes us unique?RanajitDas12
1. Humans evolved from ancient hominins in Africa such as Ardipithecus ramidus that lived 4.3 million years ago. Key traits that emerged included bipedalism, larger brains, and precision grip.
2. Homo erectus that emerged 1.8 million years ago showed more advanced social behaviors and used sophisticated stone tools and fire. Homo sapiens emerged in Africa around 200,000 years ago.
3. Several traits make humans unique, including high-level abstract thinking enabled by large brains, advanced language abilities, cooperative social behaviors, and intricate tool-making skills. Many of these traits evolved through competition and natural selection.
Plato argued that societies require a "noble lie" to maintain social control and stability. In his work The Republic, he describes an ideal city divided into categories of rulers, auxiliaries, and farmers, with each person's place determined by the metal found in their soul - gold, silver, or iron. The rulers would tell the noble lie that this categorization was due to God's will rather than circumstances. The lie was meant to keep the lower classes content with their place in the social structure.
Coda: The sting in the tail - Meetup session 23William Hall
This is the last of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
A coda is a generally short and more or less independent passage added to the end of a composition so as to reinforce the sense of conclusion. Here I consider the question raised in the title of this Meetup series - what does the understanding of the roles of cognitive technologies developed in this book tell us about the future of humanity? I see three possible scenarios, only one of which is moderately benign.
Which of these will come to pass depends critically on how successful we are at understanding who we are and applying the tremendous body of knowledge we have assembled over our history.
Failing to learn from Australia’s most successful defence projectWilliam Hall
Presents the history of the now defunct Australian defense contractor, Tenix Defence, as a case study in success and failure in managing large engineering projects.
Over its 20 year history, (2) Tenix successfully completed Australia's largest defense ($7 bn) project to build 10 ANZAC Frigates for Australia and New Zealand on-time, on-budget, for a healthy company profit against a stringently fixed price contract; and customers that are still happy with their ships and support 7 years after the last ship was delivered; and (2) failed so miserably on the next largish project to build 7 simpler ships for New Zealand that Tenix's owners decided to auction all of their defence assets. Also, in the 21st Century and despite the ANZAC success, the $8 bn Air Warfare Destroyer (AWD) project to build 3 ships is years behind schedule and billions over budget.
For more than 17 years of this history the author was a knowledge management systems analyst with access to most areas of company operations and thus able to observe sources of the successes and failures (including from the vantage point of Tenix's bid development for the AWD. The presentation shows that most successes and failures related to the ways in which Tenix managed their corporate and human knowledge, and attempts to infer some critical lessons that should be learned from this history.

Which of these will come to pass depends critically on how successful we are at understanding who we are and applying the tremendous body of knowledge we have assembled over our history.
Failing to learn from Australia’s most successful defence projectWilliam Hall
Presents the history of the now defunct Australian defense contractor, Tenix Defence, as a case study in success and failure in managing large engineering projects.
Over its 20 year history, (2) Tenix successfully completed Australia's largest defense ($7 bn) project to build 10 ANZAC Frigates for Australia and New Zealand on-time, on-budget, for a healthy company profit against a stringently fixed price contract; and customers that are still happy with their ships and support 7 years after the last ship was delivered; and (2) failed so miserably on the next largish project to build 7 simpler ships for New Zealand that Tenix's owners decided to auction all of their defence assets. Also, in the 21st Century and despite the ANZAC success, the $8 bn Air Warfare Destroyer (AWD) project to build 3 ships is years behind schedule and billions over budget.
For more than 17 years of this history the author was a knowledge management systems analyst with access to most areas of company operations and thus able to observe sources of the successes and failures (including from the vantage point of Tenix's bid development for the AWD. The presentation shows that most successes and failures related to the ways in which Tenix managed their corporate and human knowledge, and attempts to infer some critical lessons that should be learned from this history.

This presentation explores the basis for scientific rationality by testing our claims about the world against nature as described by Karl Popper's evolutionary epistemology versus accepting claims based on justified true belief. The presentation is particularly concerned to show the philosophical problems with religious fundamentalism.

This presentation looks at the case study of Tenix Defence and the nature of a ship and its crew from biological points of view to understand how they functioned as autopoietic (i.e. "living") entities in their respective environments.
Episode 5(6): Writing and the rise of autocratic religions, states and empire...William Hall
This is the 21st of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
According to the original schedule published early in the year, this session was supposed to conclude Episide 5 with the topic "Rise of socio-technical organizations & cyborgs" covering writing, printing and the emergence of autopoietic organizations based on the use of technologies enabled by the Scientific and Industrial Revolutions. However, following on from researching the implications of Lynne Kelly's work on mnemonics as discussed in Session 20 and the transition from using formal mnemonic methods for managing cultural knowledge to using writing for managing this knowledge, I have found the topics far too complex to be covered in one session. Thus, tonight's session focuses primarily on the transition from mnemonics to writing, and how these profoundly different technologies have affected the cognitions and societal structures of the populations making the transition from the practice of mnemonics to writing.
Session 21- Cadenza was, originally intended to present my personal experiences as a documentation and knowledge management systems analyst and designer in implementing computer-based knowledge management technologies in the Australian engineering project management company, Tenix Defence primarily responsible for the $7 BN ANZAC Ship Project. However, given that I have already made two public presentations on this topic:
● Failing to learn from Australia’s most successful defence project. SIRF 2nd KM Roundtable 2015, South Melbourne, 26/5/2015 (http://www.orgs-evolution-knowledge.net/Index/Essays/Presentations/How%20not%20to%20learn%20lessons(web).pdf), and
● Socially Constructing Warships — Emergence, growth & senescence of a knowledge-intensive complex adaptive system. Melbourne Emergence Meetup, University of Melbourne, 11 June 2015 (http://www.orgs-evolution-knowledge.net/Index/Essays/Presentations/SociallyConstructingWarships(1).pdf)
I see no need to repeat that discussion here, and will devote the present Session 21 to the societal impacts of the printing and microelectronics revolutions that have had equally profound implications for the ever more rapidly changing processes of human cognition and complexity of human social systems.
Life, Knowledge and Natural Selection ― How life (scientifically) designs its...William Hall
The document discusses major revolutions in how life stores and processes knowledge over time, from the emergence of the first living systems to modern technological advances. It outlines three key revolutions:
1) The emergence of genetic memory in DNA and RNA around 4 billion years ago, allowing life to store knowledge across generations.
2) The development of multicellular memory and neural networks in brains between 2-1.5 billion years ago, greatly increasing an organism's processing power.
3) The rise of cultural memory and knowledge sharing through language, writing, and communication starting around 5,000 years ago, enabling societies to collectively store and build upon knowledge over generations.
DWS15 - Game Summit - Fabien Delpiano - PastaGamesIDATE DigiWorld
This document discusses the benefits of both original creations and work for hire for game developers. It describes how the company Pastagames started with original self-published games but struggled to gain visibility. They then found success doing work for hire projects that allowed them to fund their own creations and gain industry connections. The document argues that both original works and work for hire each have benefits, and provides historical examples of famous artists like Michelangelo and Picasso who produced renowned works through commissions or paid jobs.
DWS15 - Future Digital Economy Forum - More on Moore's Law - Giorgio Cesana ...IDATE DigiWorld
Gordon Moore observed in 1965 that the cost per component of integrated circuits decreases as more components are packed onto a single chip. He predicted that by 1975, costs would dictate fitting 65,000 components on a single chip. While technology has allowed for exponential increases in components per chip since then, Moore's Law has ended economically as the manufacturing cost per component is no longer decreasing. Further advances in geometry scaling are increasingly difficult and expensive to achieve, raising questions about how long such scaling can continue to be economically viable.

A manutenção preventiva inclui proteger o hardware contra poeira e umidade, verificar as instalações elétricas e usar software antivírus. A manutenção corretiva envolve ferramentas de diagnóstico, identificação de problemas no hardware e instalação de drivers.
Here's an overview of what we covered in the first CHASER TRAINING on June 20th, 2011 in #YYZ.
Please note not all strategies discussed in the session are included.
421 672 Management Of Technological Enterprises(2008 Tutorial 1)William Hall
The document discusses the importance of knowledge management for technological enterprises and engineering organizations. It outlines how people, processes, and technology infrastructure are all needed to effectively manage organizational knowledge. It provides examples of what can go wrong when knowledge is not properly managed, such as cost overruns, schedule delays, and safety incidents. The Challenger disaster is discussed as an example where failures in managing critical engineering knowledge led to loss of life.
The document provides tips and generalizations for various phases of engagement with diverse communities. It suggests being aware of how your process may be perceived and adjusting your practice based on accurate generalizations about cultural differences. This includes considering how messaging, outreach methods, facilitation approaches, and process design need to account for different preferences and histories among target populations to promote inclusion and obtain meaningful participation. The goal is for organizers to authentically understand community perspectives in order to effectively engage diverse groups.
Episode 5(1): Introducing Episode 5, our ancient ancestors and their relative...William Hall
This is the 16th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
This presentation begins the last, largest and most complex episode in my fugue, where I explore from a biological rather than a technological point of view the emergence and evolution of humanity from a lineage of tool-using apes.
Some 4 million years one among several species of apes began to evolve the cultural capacity to share among themselves hyper-exponentially growing volumes of complex technical knowledge about the world. This knowledge gives us and our organizations the strategic power to control the entire biosphere of Planet Earth and the mineral and atmospheric resources supporting the biosphere.
Tonight's episode presents a step-by-step evolutionary hypothesis explaining how modern humans came to be and how the development of the cultural transmission of knowledge among groups led to the emergence of modern social and economic organizations.
Topics for this session of the Meetup include:
● Basic concepts of evolutionary and comparative biology
● A review of the material evidence about our ancestry and early evolution
I'll also say a bit about Homo naledi, described as a new species of human in a paper published this week (of September 13, 2015) by Lee Berger et al. The description, based on more than 1550 parts of more than 15 individuals found in a nearly inaccessible chamber of the Rising Star cave system near Johannesburg South Africa, is of a hominid species with a chimpanzee sized brain and a mosaic of features with resemblances to Australopithecus and early Homo. There is no dating evidence, but the features suggest this species may have been very close to the stock from which all Homo (humans) evolved.
Episode 5(3): Where and how we started our path to now - Meetup session 18William Hall
1. Capuchin monkeys in the wild demonstrate sophisticated tool use, such as cracking nuts open with stone hammers and log anvils, which requires multiple step problem solving.
2. Their nut-cracking behavior shows transmission of technological knowledge across generations, as young monkeys learn the process.
3. Capuchins' tool use intelligence suggests that under the right evolutionary pressures, such as those early hominins faced as the African Eden deteriorated, it is possible for primates other than humans to develop advanced cognition and culture.

The Importance Of Human Evolution
This document discusses human evolution from early hominin species like Australopithecus to modern humans. It describes some of the major species in human evolution such as Homo habilis, Homo erectus, Homo neanderthalensis, and Homo sapiens. Key developments discussed include the evolution of bipedalism, increasing brain size, tool use, adaptations to climate, and genetic changes over millions of years that have resulted in modern humans.
Modern humans originated in Africa around 200,000 years ago. Genetic studies show all living humans are related through a single female ("Mitochondrial Eve") who lived around 150,000 years ago in East Africa, and a single male ("Y-chromosomal Adam") who lived between 120,000-156,000 years ago. While humans share 99% of our DNA worldwide, we diverged genetically from chimpanzees around 10 million years ago and have evolved significantly larger brains and bipedalism compared to our primate ancestors.
This document provides information on human evolution and different types of societies. It discusses four categories of hominids (Sahelanthropus, Ardipithecus, Australopithecus, Homo), with details on several types of Homo (H. habilis, H. erectus, H. sapiens, H. floresiensis, H. naledi, H. rudolfensis, H. heidelbergensis). It also outlines the differences between H. sapiens neanderthalensis and H. sapiens sapiens. The document describes six types of societies (hunting and gathering, pastoral, horticultural, agricultural, industrial, post-industrial)
1. Anthropology is defined as the comparative and holistic study of humankind.
2. It is comparative in that it compares cultures across time and space, as well as related species.
3. It is holistic in that it considers all aspects of a culture and how they integrate together.

This document provides an overview of the four main subfields of anthropology: socio-cultural anthropology, linguistic anthropology, archaeology, and physical/biological anthropology. It describes the focus and methods of each subfield. Socio-cultural anthropology studies contemporary human societies and cultures through ethnography and ethnology. Linguistic anthropology examines language and its relationship to culture and society. Archaeology studies past cultures through excavating and analyzing material remains. Physical anthropology focuses on human evolution and biological variation.
The document discusses human evolution and several early hominid species, including Homo habilis, Homo erectus, Homo neanderthalensis, and modern humans. It describes how humans first evolved in Africa and traces the evolution of traits like bipedalism. Key points made include that Homo habilis was the first tool-making hominid and Homo erectus was one of the first hominids with modern human-like body proportions. The document also discusses evidence of interbreeding between early hominids like Neanderthals and modern humans.
The document summarizes research that uses analysis of DNA polymorphisms on the non-recombining region of the Y chromosome to trace the dispersal of human populations. Key findings include:
- Analysis of Y chromosome polymorphisms in over 1,000 men from 52 populations identified 131 haplotypes and 10 haplogroups.
- Maximum parsimony analysis estimated the time to the most recent common ancestor of human Y chromosomes to be around 60,000 years ago.
- The geographic distribution of haplogroups provides insights into early human migration routes out of Africa and the colonization of the world.
This document provides a briefing on the history of long-range historical comparative linguistics, beginning with early studies in the 17th-18th centuries exploring linguistic connections between various language families. It then discusses the foundational work of Trombetti in 1902 establishing the monogenesis of language based on the comparative method. The briefing outlines major schools and scholars who have further developed long-range comparative linguistics such as the Italian, USSR, USA, and Iran schools from the 20th century onward.
This document provides an overview of the field of long-range historical comparative linguistics, beginning with Trombetti's founding of the doctrine of monogenesis of language in 1902 based on Junggrammatiker scientific linguistics. It then discusses schools of thought that further developed the field, including the USSR school founded by Illich-Svitych, the USA school including Greenberg and Ruhlen, and the Iran school of Assadian. The document also briefly discusses human migration based on genetic evidence from mitochondrial DNA and Y-chromosome studies, which corroborate the linguistic findings on the origin and migration paths of anatomically modern humans out of Africa.

The document discusses the Herto Homo sapiens fossils found in Ethiopia and their significance for understanding human origins. The fossils discovered included two adult skulls (one with intact facial bones) and a child's skull that were reconstructed over three years of cleaning. Artifacts found at the site included other Homo sapiens remains and hippopotamus bones cut with stone tools. Measurements of the skulls showed they were directly related to anatomically modern humans, providing evidence against theories of interbreeding between distinct human populations in Africa, Asia, and Europe. The well-preserved Herto fossils provide key information about early Homo sapiens in Africa.
This document provides an introduction to anthropology and the study of human societies and culture. It discusses the origins and early development of anthropology as a field. It also summarizes the key topics covered in subsequent chapters, including the origin of man based on evolutionary theory, the development of human societies and thought, what defines culture and its components, and how culture influences and shapes human behavior.
The document discusses the origin and evolution of humans from several perspectives. It first explores the uniqueness of human experience and various theories about human origins, including evolution, UFOs, and the Bible. It then examines the nature of humans, comparing our advanced reasoning and willpower to animals. The document also outlines some negative human traits like violence and connections to evil or God. Finally, it delves into the evolutionary process that led to modern humans, tracing key developments in anatomy, tool use, communication, culture, and tracing the evolution of species from australopithecines to Homo sapiens.
Welcome to the Western Original Sin & Fare Thee Well in HellEditions La Dondaine
I just published Welcome to the Western Original Sin & Fare Thee Well in Hell. James Harrod is a misguided white supremacist who thinks he is the archangel Gabriel. He uses a fiery keyboard on his computer to reject all those who do not speak Turkic languages, Indo-European languages, and Indo-Aryan languages. And he rejects the people who live in sub-Saharan Africa, you know all these black people, back to the dying hell of their jungles. He is one step away from rejecting all Asian people who speak any sort of isolating language, and he remains neutral about it, meaning he is guilty by proxy.
This document discusses memetics as a way to understand cultural evolution in humans. It proposes that memes, defined as units of cultural information or ideas that are replicated between minds, drive sociocultural evolution in a similar way that genes drive biological evolution. The document outlines Richard Dawkins' concept of memes and how they spread through imitation and communication. It suggests that analyzing the replication and selection of memes could provide insights into how complex human cultures and social systems have formed over time.
This document provides a summary of recent genetic studies that have revealed new information about interactions between Neanderthals, Denisovans, and Homo sapiens. The studies indicate there was both replacement and interbreeding between these groups. This has challenged the two main models for the origin and evolution of Homo sapiens - the Out of Africa and Multiregional hypotheses. The document reviews these models and discusses how the new genetic evidence supports elements of both and suggests a more complex history than either model alone can explain.

Episode 5(7): Printing: "freedom" and the emergence of knowledge based autopo...William Hall
This is the 22nd of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species.
When I started this series I had not yet finished writing the final parts of Episode 5 or fully understood the importance of mnemonic technologies in the emergence of agriculture and industry. In my original schedule, I also underestimated the extent of material to be covered to explain the evolutionary origins of today and tomorrow's post-industrial humans. Thus, to properly conclude Episode 5 I have decided to skip the Cadenza section entirely.
The Cadenza was intended to explore how I applied many of the ideas about cognitive technologies presented in this series in my professional work as an engineering knowledge management systems analyst and designer for Tenix Defence that helped to ensure the successful completion of the $7 BN ANZAC Ship Project supplying 10 frigates to the Australian and New Zealand Navies. The project was unusual in that as part of the contract, besides constructing the ships, Tenix was required to provide a complete package of engineering technical data and knowledge regarding ship maintenance, logistics, and operations. What we did at Tenix is still state-of-the-art, but I do not need to tell the story here as the material I intended to present has already been covered quite thoroughly in the presentations referenced in Session 21.
Tonight, in lieu of presenting my Cadenza, I will finish Episode 5 by considering how the printing revolution again fundamentally changed the structure of society from a largely autocratic system to freer and more egalitarian systems. Mass printing and near universal literacy removed many controls over access to technical knowledge, enabling the Reformation and the Scientific and Industrial Revolutions. It also provided the basis for the emergence of individual entrepreneurs and knowledge based corporations as autopoietic systems.
Beginning with the spread of universal literacy with the Printing Revolution that also put the exponential growth and spread of knowledge into hyper drive, I then explore ideas relating to the inseparability of living knowledge and autopoiesis as discussed in the presentations for Sessions 13 and 14. The following papers provide the basis for these sessions and the discussion here:
Vines, R., Hall, W.P. 2011. Exploring the foundations of organizational knowledge. Kororoit Institute Working Papers No. 3: 1-39.
Hall, W.P. 2011. Physical basis for the emergence of autopoiesis, cognition and knowledge. Kororoit Institute Working Papers No.2: 1-39.

1) Technological convergence is merging human biology and cognition with various sensor, effector, cognitive, and communication technologies through interfaces like smart devices, implants, and neural links.
2) Moore's law is enabling more intimate human-computer interfaces like smart contact lenses, neural implants, and brain-computer interfaces that can control prosthetics.
3) Mapping the human brain's functional organization and simulating its processing through neuromorphic architectures allows cognitive convergence where brain activity can control external devices wirelessly through increasing bandwidth.

The document discusses different levels of organization in living systems and the emergence of autopoiesis and knowledge at each level. It covers:
1) The emergence of autopoietic cognition at the molecular level through self-regulation and feedback control embodied in molecular structure.
2) The codification of self-regulatory knowledge in self-replicating macromolecules like DNA, RNA, and proteins.
3) Higher levels of autopoiesis and knowledge at the cellular level in prokaryotes and eukaryotes, and then at the multicellular level in tissues, organs and organ systems.

1) The document discusses concepts from physics such as dynamic systems, chaos theory, attractors, and thermodynamics and how they relate to the emergence of life and knowledge.
2) It defines autopoiesis as a self-regulating, self-sustaining system that is produced by its own network of productions. Autopoietic systems embody structural knowledge that allows them to survive perturbations.
3) Knowledge emerges through the iterative process of systems solving problems of survival via autopoiesis. Systems that can persist by solving new problems perpetuate successful solutions, while those that cannot disintegrate and lose their accumulated knowledge.

This is the 12th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. This presentation wraps up my discussion of the history of technologies used to enhance and extend human cognition. Because most of what I had planned for this talk has already been covered and/or discussed in the previous presentations, I thought that it would be much better to take the chance for a general review discussion of the main take-home messages to now, and to give a preview what remains to be covered in the second half of the series.
Episode 3(3): Birth & explosion of the World Wide Web - Meetup session11William Hall
This is the 11th of of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. In presentation I show how a universally accessible library for the body of human knowledge emerged from what started as defense projects to interconnect various projects so they could share computer resources and to harden digital communications against nuclear warfare. Tonight's topics cover:
● ARPANET and the invention of addressable digital communications
● Vannevar Bush, Memex, and the revolutionary invention of hypertext
● Revolutionary tools for authoring, managing, and delivering hypertext
● Exponential growth of the web and web content
● Using the Web's automated cognition for assembling and retrieving relevant knowledge

This is the 10th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. Here I show how preserving knowledge externally to the human mind extends cognitive processes beyond the single individual to social and automated systems. Information science covers the dissemination, indexing, management and retrieval of scholarly, scientific and technical knowledge. Topics include:
● Moving indexes and the whole library on-line
● Principles of indexing and semantic retrieval
● Increasing costs of publishing paper and managing physical libraries
● The research library is dead - long live the World Library of the knowledge society

Episode 3(1): Cognitive tools for the individual - Meetup session 9William Hall
This is the 9th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. Here I discuss how ersonal computers give individuals cognitive tools to convert thoughts into explicit electronically realized objects that can be independently stored, copied, communicated, retrieved, shared and even processed semantically:
● Word processors replace the paradigm of structured pigment on inert andponderous paper into durable but infinitely malleable electronic documents.
● Calculators and spreadsheets automate and give life to the structured patterns of numbers and symbols on paper.
● Databases extend and automate two dimensional tabular formats on paper into multiple dimensions
● The revolutionary differences between electronic documents and symbols and words on paper are still not fully understood by those who use them
● The paradigm of a structured document is even more revolutionary in that it enables external automation to understand syntax and semantics to cognitively process document content
Episode 2(2): Electronic automation and computation - Meetup session 8William Hall
This is the 8th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. This this session explores the consequences of adding electrons to the automation equation in the 1940's, which fueled the hyperexponential evolution of technology that during my lifetime has radically changed and today and tomorrow continues to change the nature of humans and humanity. Topics include:
● The revolutionary generations of electronic computer technology
● Introducing Moore's Law - a theme that will be returned to several times in the remainder of the book
● Revolutions in the application of control (i.e., strategic power): from manipulating switches to casting spells.
Episode 2(1): Mechanical automation and calculating - Meetup session 7William Hall
This is the first of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. This 7th session explores how mechanical computation and automation in the ancient Greek world contributed to the rise of mechanical computation in the first half of the 20th Century. Topics include:
● Extending human capabilities with automation and automated replication
● Showing that the ancient Greeks were a lot smarter than many people know -
○ the 2100 year old Antikythera Mechanism was used to compute astronomical events
○ the use of automation added magic to temple spectacles
● Greek automation seems to have contributed to 18th Century androids and automatons
● The contribution to escapements, clocks, and mechanical digital computation through the mid 20th Century

Episode 1: Early technologies for making living memory explicit - Meetup sess...William Hall
This document provides a summary of early technologies for recording and sharing knowledge, including:
1) Counting and basic forms of writing developed as ways to keep records of economic transactions. Printing later allowed mass replication of written knowledge for wider dissemination.
2) Libraries and catalogs helped organize growing bodies of written knowledge, but most transmission was by hand copying, limiting access. Printing made knowledge more accessible by enabling standardized mass production of texts.
3) Emerging technologies like moveable type, paper production, and the printing press enabled new economic models for knowledge by allowing hundreds or thousands of copies instead of just one. This fueled advances like the Renaissance, Reformation, and scientific revolution by more widely sharing information.
Understanding the adaptive value of knowledge - Meetup session 5William Hall
This is the 5th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. Issues raised in the book's Counter Subject are explored:
(1) Relating data, information, knowledge, wisdom.
(2) Understanding the transformation of data, information and knowledge into strategic power over external circumstances.
(3) Understanding evolutionary and revolutionary adaptations to life's problems.
Epistemology, technology and knowledge growth - Meetup session 4William Hall
This is the 4th of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. Here I get into the Subject or meat of the book, building on Karl Popper's evolutionary epistemology and Thomas Kuhn's scientific revolutions.
Reading and writing a massive online hypertext - Meetup session 3William Hall
This is the third of 23 presentations in a series introducing and outlining my hypertext book project, "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge. The project explores the interactions of technology and cognition in the extraordinary evolutionary history of the human species. This 3rd session covers three things about the hypertext: (1) how it reflects scholarly/scientific understanding, (2) how this is implemented and may be published, and (3) my apps toolkit.
Application Holy Wars theme and why the book was writtenWilliam Hall
William Hall provides an overview of his career and experiences that led him to write a book about "application holy wars" and the roles of computers and documentation in corporate success. He discusses growing up with interests in science and engineering. His education included studies in physics, zoology, evolutionary biology, and the history of science. Professionally, he worked as a university lecturer and researcher before moving to roles managing technical documentation at a bank and defense company. Hall witnessed failures to understand the strategic importance of new technologies within organizations. The document outlines questions about paradigms, knowledge, and life that motivated Hall to write the book.
Introducing a new way to explore evolution of human knowledge & technologyWilliam Hall
This document introduces a new hypertext book project called "Application Holy Wars or a New Reformation - A Fugue on the Theory of Knowledge". The book explores the co-evolution of human technology, cognition, and organizations through history in a non-linear hypertext format. It is organized as a fugue with different themes that are woven together. The author provides an outline of the key themes and episodes to be covered in the book and describes plans to road test the content through a series of Meetup discussions.

Topic 1 ― Sustainability and the “tragedy of the commons”
Infrastructure includes those components of the complex system of systems comprised of the environment and people responsible for mediating the material and energetic interactions of people, systems and their environment.
To successfully engineer infrastructure for sustainability you must understand the human components as well as the environmental components.
Topic 2 ― Theories of organization and knowledge
Physical theories are the basis for structural engineering.Theories of knowledge and organization are the basis for enterprise engineering. Knowledge has a physical basis.
The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
Discovery of An Apparent Red, High-Velocity Type Ia Supernova at 𝐳 = 2.9 wi...Sérgio Sacani

Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (

Ca-rich population. Although such an object is too red for any low-

cosmological sample, we apply a fiducial standardization approach to SN 2023adsy and find that the SN 2023adsy luminosity distance measurement is in excellent agreement (

Λ
CDM. Therefore unlike low-

Ca-rich SNe Ia, SN 2023adsy is standardizable and gives no indication that SN Ia standardized luminosities change significantly with redshift. A larger sample of distant SNe Ia is required to determine if SN Ia population characteristics at high-

counterparts, and to confirm that standardized luminosities nevertheless remain constant with redshift.
Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Hominin evolution and
environmental
variability over the
past 7 million years.
Alternative responses
to variability
– Genetic adaptation
(change)
– Cultural change
– Cultural accumulation
13. Genes & memes – genetic vs cultural adaptation
Genes
– Determine individual anatomical, physiological and neurological
capacities
– Mutation: physical change to one or more DNA nucleotides on a
chromosome
Change is slow multi-generational process depending on natural selection
Movement rather than increased versatility
Meme = unit of culture (an idea or value or pattern of behavior or
knowledge) that may be passed between individuals or from one
generation to another by non-genetic means
– Change often intra-generational depending on innovation, social
relationships and processes
– Transmission limited by genetic capacity to communicate detailed
information
– Essential information easily lost or corrupted over generations.
– Rate and extent of cultural accumulation depend on genetic capacity,
group size, (culturally transmitted) cultural practices13
14. Adaptation = application of genetic or cultural
knowledge to solve problems of life
Natural selection on genes works at the level of
individual genetic variation depending on successes of
carriers of particular genes in the population
Selection on cultural knowledge works at the level of
culturally variant groups, depending on successes of
the different groups.
– A group whose shared cultural knowledge allows it to solve
problems other groups can’t solve grows at the expense of those
other groups
– Successful items of cultural knowledge may be carried by
individuals between groups to speed the evolutionary arms race
Rate of cultural evolution depends on individuals’
genetically determined capacities to understand,
remember, and transmit cultural knowledge14
15. Niche shifts (left) vs niche expansions (right). Vertical axis
represents survival probability of particular phenotypes.
Niche shift
– Mutation is blind
– Natural selection tracks current requirements, generally with continuing
specialization
Niche expansion
– Retain original adaptation together with adding new capabilities, i.e.,
accumulation or (very rare) cases of gene duplication and functional divergence
– New mutation crosses adaptive threshold opening new adaptive landscape (i.e.,
grade shift)15

Brain capacities correlate with cognitive capacities (many works over many years).
Major climatic pulse (expansion/contraction E African Rift lakes) causes rapid
ecological variation ~1.8 mya
– Proliferation hominin species
– Initial colonization of Eurasia (Dmanisi)
– Rapid increase in brain capacity in H. erectus (broadly defined)
– Acheulean hand axes begin to appear around 1.7 mya.

Rift (Olduvai, etc.) between 3.0 and 1.5 mya

each) of magnified moist-arid
variability occurred between
3.0 and 1.5 mya.
Possible modes of adaptation
– Fail to track (= extinction)
– Track with adaptive change (shift niche)
– Become more versatile (expand niche)
Limits to genetic adaptation
– Slow & ponderous (intergenerational)
– Do one thing or the other not both
Cultural adaptation
– Fast (intragenerational)
– Group-based phenomenon – cultural
knowledge pertains to group not particular individuals
– Group knowledge easily lost (dependent on intergenerational knowledge transfer, in turn
dependent on genetically determined capacities, group size, structure, and dynamics)
– Culturally transmitted knowledge relating to tool-making and use was grade-shifting
Savanna ape inherited limited capacity to transmit cultural knowledge and existing
culture of simple tool-making and use from CLCA

21. Hominins using haak en steek branches as tools (Guthrie 2007): a. for driving big cats away from
their prey. b. for hunting - given the simple conversion of a thorn branch into a "megathorn" lance.
Cooperative defense and scavenging of carnivore kills cached in trees
gave early hominins increased access to meat on the savanna
Simple requisites for grade shift to aggressive scavenging on the ground
– Coordinated & cooperative defense and offense using effective deterrence
– Oldowan butchering tools for cutting skin & ligaments
21
Savanna offers limited resource of edible plant foods but
a rich supply of grass-eating herbivore meat
Chimpanzee social defence against leopards is uncoordi-
nated mobbing with clubs as per video (click to view)
- Might deter leopard from returning to tree cache
- Not a pride of lions or mob of hyenas on ground
22. 22
With thorn branches, spears and stone butchering tools,
hominins became top carnivores on the savanna
Oldowan tools made & used
from 2.6 to 1.7 mya
– Hominin teeth can’t tear skin
and flesh of large prey
– Anvils & hammer stones used to
access marrow from scavenged
carcasses
– Kanzi the bonobo learned to
break stones & use flakes as cutting tools
– Early hominin culture assimilates knowledge that broken hammer stones
can be used to cut skin & ligaments for butchering large prey before
lost to competing carnivores and scavengers
More sophisticated Acheulean hand choppers & other tools made
& used from 1.7 mya to 0.1 mya facilitated butchering but
required greater knowledge & dexterity to make
Note exceedingly slow rate of technological change
– Suggests neural/social/linguistic capacity to accumulate knowledge
of complex technologies was stringently limited for most of hominin
history
23. 3 mya cooperative and
aggressive scavenging of
kills reduced food supply
for some species of
carnivores causing local
extinctions.
1.8 mya tool-using hominins
in Olduvai Gorge were top
carnivores selectively
hunting prime quality bovid
prey.
By 1.77 mya carnivorous
hominins extended to Dmanisi,
Georgia, and soon spread across Asia and into Europe (as H.
erectus)
By 3 to 2 mya hominin competition and dominance of other carnivores
begins to reduce overall carnivore diversity in E. Africa
23
Werdelin & Lewis 2013.
24. Genetic enhancements to meet increasing cognitive needs
– Capacity for geographical (mental map) and natural history knowledge
– Understand time & process to plan & coordinate hunting
– Better neuromuscular control and knowledge of resources & planning
for tool making & use
– Increased capacity for teaching & learning
Facilitate master-apprentice and other social relationships
Share and direct attention to critical aspects of process & technique
Use gesture, mime and acting-out (dance)
Cultural accumulation of knowledge begins to replace genetic
change as most important adaptive mechanism
– Knowledge accumulation still limited
Capacity to remember
Slow genetic evolution of more memory capacity
– Technological innovations may be lost & reinvented several times & may
take hundreds of thousands of years to be consolidated

26. Popper’s evolutionary theory of knowledge
Natural selection builds knowledge (= solutions to problems)
26
Pn a real-world problem faced by a
living entity
TS a tentative solution/theory.
Tentative solutions are varied
through serial/parallel iteration
EE a test or process of error
elimination
Pn+1 changed problem as faced by an
entity incorporating a surviving
solution
The whole process is iterated
All knowledge claims are constructed, cannot be proven to be true
TSs may be embodied as “structure” in the “knowing” entity, or
TSs may be expressed in words as hypotheses, subject to objective criticism; or as
genetic codes in DNA, subject to natural selection
Objective expression and criticism lets our theories die in our stead
Through cyclic iteration, sources of errors are found and eliminated
Solutions/theories become more reliable as they survive repetitive testing
Surviving TSs are the source of all knowledge!

27. Knowledge-based autopoietic groups as higher-order
evolutionary entities
Accumulated knowledge determines system’s structural adaptations to
ensure survival and (re)production
An entity is defined to be autopoietic if it exhibits all the criteria
– Bounded (groups geographically and socially separated with culturally regulated
and limited mixing)
– Complex (groups formed of several to many individuals playing various different
roles in group)
– Mechanistic (energetically/economically driven interactions of group individuals
determine group functions)
– Self-referential (group identity and boundaries determined by culturally
transmitted knowledge)
– Self-producing (group retains its continuity beyond the lifetimes of single
individuals through individual reproduction and recruitment combined with
indoctrination in and transmission of accumulated cultural knowledge from one
generation to the next)
– Autonomous (the group manages its own survival and continuity through
knowledge-based interactions of its individual members)
Hierarchically nested systems possible
– Cells Organisms Social organizations Communities

higher order autopoietic systems
Drivers for the evolution of a faculty of language
– Coordination of individuals’ involvement in group activities and
society
– Facilitates transfer of the body of essential cultural (i.e.
survival) knowledge/heritage
Survival knowledge shared and propagated via language
among the group and across generations determines
success on the adaptive landscape – group selection
Language - Phenomenon of groups not individuals
Probably evolved > 500kya in common ancestor to Homo
sapiens, Neanderthals and Denisovans
Common language, cultural norms & xenophobia
determine and help to maintain boundaries of
knowledge-based groups
32
33. 33
Cognitive skills needed to accumulate knowledge for niche expansion
(Vaesen 2012; Sterelny 2011, 2012a, b)
Hand-eye coordination - fine motor control needs more neurons
Causal reasoning - time-binding; understand goals, actions, and
consequences
Function representation - associate particular tools with
particular jobs
Natural history intelligence - conscious attention to
understanding the behaviors of predators, prey, fire, other
changing aspects of environment
Executive control – anticipating, deciding & planning; not just
reacting
Social intelligence - extended childhood, social learning (imitation
not emulation), understanding of intentions of others (mirror
neurons?), focused teaching & learning, apprenticeship
Intragroup coordination
Intergroup collaboration
Language

35. Language and the emergence of hominin groups as
higher order autopoietic systems
Language - phenomenon of groups not individuals (one hand clapping = nonsense)
Drivers for the evolution of a faculty of language
– Coordinates individuals’ involvement in group activities and society
– Transmits essential cultural knowledge (heritage)
Common language, cultural norms & xenophobia determine group boundaries
Cultural knowledge propagated among individuals between generations by language
determines group success on the adaptive landscape
An entity is autopoietic if it exhibits all the criteria (Varela et al. 1974)
– Bounded (groups separated socially by cultural differences and breeding systems)
– Complex (groups formed by multiple individuals playing different roles in group)
– Mechanistic (interactions of group individuals determine group functions & activities)
– Self-referential (group identity determined by culturally transmitted knowledge)
– Self-producing (group retains its continuity beyond the lifetimes of single individuals
through individual reproduction and recruitment combined with indoctrination in and
transmission of accumulated cultural knowledge from one generation to the next)
– Autonomous (group manages its own survival and continuity through knowledge-based
interactions of its individual members)
Autopoietic entities represent units of selection
Pre-linguistic groups probably qualified as autopoietic – but group identity and
adaptive variation greatly strengthened by language-assisted cultural accumulation

Routledge, Oxford, pp. 115-132
• Pre Neanderthal
• Seasonal hunting camp
• Level I (the older)
– flint artifacts,
– more than a thousand bones of ten mammalian taxa,
– 4 worked silver fir branches with diagonal grooves cut
into one end – probably for holding sharp flakes
(oldest known compound tools)
• Level II single season’s hunting camp containing
more than 25,000 well preserved bones, (>90%
horses showing signs of butchery. Four separate
hearths were also identified. All stone artifacts
were flint brought the site ready made. The only
flint debris is from retouching, and bone
retouching tools were also found. Wooden tools
included a double pointed throwing stick and nine
wooden spears or throwing javelins with flame
hardened tips ranging in length between 1.8 and
2.5 m left (ritually?) with prey remains
• Organization & capacity suggests language
39. 39
How much knowledge does it take to make & use tools?
Killing prey with stone-tipped spears
Understanding cognitive demands of technologies
Thinking a stone-tipped spear
– sequence of steps to make a spear used to bring down prey (chains
of operation/cognigram)
– making a bow and arrow set is at least 3x more difficult
– each arrow indicates ordered application of specific knowledge
(Lombard 2012; Lombard & Haidle 2012)
40. Development of increasingly complex
stone tools (Stout 2011) correlates
with larger brain capacity and
language development.
Even with language, knowledge is
limited by what can be learned,
remembered, and passed on by
single individuals.
By < 500 kya, pace of change in the
capacity to deal with multiple
complexities is too fast for genetic
adaptation
< 50 kya increasing rate of change
suggests major innovation to support
accumulation of much larger volumes
of knowledge.
What enabled increasing tool complexity?

Introduction & exponential
growth of new technologies
41. Modified from Krubitzer & Stolzenberg (2014)
“All modern human populations have
language, and there is no difference in
language capacity between living human
populations. Parsimony implies that the
most recent common ancestor of all
modern humans had language, and had
all the biological prerequisites for
language” (Johansson 2013).
The common distribution of language
proxies across human and neanderthals
in genomic, paleoanthropological, and
paleoarcheological contexts show that
human, Denisovan and Neanderthal
common ancestor had a capacity for
modern language, speech and culture

Schöningen
&
Bilzingsleben
Indicators for the emergence of modern
cognition in Neanderthals & H. sapiens
42. Two extraordinary snapshots imply that linguistic capabilities
already existed 400 kya in LCA Neanderthal / H. sapiens
Schöningen II (single-use hunting camp 380 kya – Thieme 2005)
– Captured, butchered and processed at least 20 horses
– Tools made elsewhere include 9 wood lances left (ritually?) with herd remains
– 4 hearths, associated tools & evidence for spit-roasting, smoking and drying
– Earliest evidence for compound tools
Bilzingsleben (base camp 370 kya - Mania & Mainia 2005)
– 3 x 3-4 m dia. huts with hearths all oriented against wind
– Prey included fish, amphibians, reptiles, birds, elephants, rhinoceros, horses,
bison, deer, pigs, lions, bears, wolves, hyenas, foxes, badgers, and martens
– Spit roasting & smoking for preservation
– Evidence for making & use of wide variety of stone and bone tools
– Paved area with artifacts suggestive of ritual activities.
Implications
– Long-range planning (harvesting and preserving; anticipating the need)
– Planning and coordinating cooperative hunting of large, dangerous animals
– Wide range of natural history, tool-making and food-processing knowledge
– Ritual activities/thinking
Diversity and complexity of cultural knowledge for inferred activities
beyond the capacity to communicate without language.

43. The Middle Stone Age (Africa) / Middle Paleolithic (Europe) was
a post Acheulian technological plateau (~ 300 → ~ 50 kya)
Primary references: Current Anthropology, Vol. 54, No. S8, Wenner-Gren
Symposium: Alternative Pathways to Complexity: Evolutionary
Trajectories in the Middle Paleolithic and Middle Stone Age (December
2013 – free to the Web)
Acheulian tools continued to be used by other hominins (e.g., H. erectus)
Technology variable through MSA / MP but no clear temporal trends
– Sporadic development and loss of complex technologies
– Operational chains of limited length
Despite major ecological shifts between glacial and inter-glacial there is
no evidence for permanent settlements or cultural shifts from nomadic
hunting and gathering.
– Little technological difference between Neanderthal/Denisovan/archaic H.
sapiens in Europe, anatomically modern sapiens in South Africa, and AM sapiens
in the Levant (eastern Med.) early colonization ~ 100 kya, and permanent
colonization and spread to Eurasia ~ 70 kya
– Populations limited in size to small bands, with evidence that Neanderthals &
Denisovans passed through more severe genetic bottlenecks than sapiens
Even with language, the capacity for cultural memory was limited43
44. Slowly increasing pace of hominin technological innovation in the
East African homeland
Even given the existence of a faculty of language, the pace of
technological innovation was very slow before 100 kya.
Use of fire in making fine
blades and points, or use of
ochre and beads may have
been developed & lost
several times before being
fixed in culture
Even where ideas can be
expressed in words, an
individual’s ability to
remember detail is limited.
Where population is divided
into small groups any
knowledge not securely
acquired by the next
generation is lost
44 McBrearty & Brooks 2000
45. Something changed ~ 70-50 kya that enabled H. sapiens to
increase its cultural capacity to store & transmit knowledge
Mnemonics – increasing capacity for accumulating knowledge in
primary oral culture differs from typographically based culture
– Primary sources for understanding mental techniques used in primary
oral cultures to accurately memorize and recall large and complex
bodies of information:

Latrobe University, Bundoora, Vic., Australia [embargoed until Cambridge University Press book is
published – see http://blog.lynnekelly.com.au/memory-and-archaeology/]
– Techniques - think memorably: express knowledge in rhythm and rhyme
with common formulas and phrases, link breathing and gesture, act out,
associate with song and dance, organize by intrinsic logic, etc.
Master technique: the method of loci (see next slide)
– May increase individual memory capacity by 10 to 100-fold or more
– Use at group level to preserve and transmit cultural knowledge
– Cultural capacity depends on group size – larger groups allow formation
of subgroups (i.e., “guilds”) to manage specialized bodies of knowledge
45
46. Method of Loci builds on the natural rhythms and progression of
life
Memorable events happen in time and space (specific locus in 3D space)
– Innate way to organize memory probably common to all “intelligent” animals
– Focus on the space-time locus to retrieve memories of circumstances and events
that happened at that locus
Songlines:
– hunter gatherers learned to consciously index geographic, resource & natural
history knowledge against tracks in the existing landscape where it is relevant.
– Other knowledge may be indexed against loci on other shared lines (e.g., stars in
the night sky) or with stories associated with landscape features, etc
Method of loci uses an ordered sequence of memorable loci as indexing
points along existing or imagined space-time lines
– Associates memorably expressed snippets of knowledge with particular loci in
the line
– Other mnemonic techniques make snippets memorable (e.g., imagery, rhythm,
rhyme, oration, song, dance)
– Group rehearsal and repetition strengthens memory traces
– Group sharing adds redundancy and corrects errors in individual memory
– In larger populations subgroups can maintain specialized knowledge
46
47. Becoming settled – surmounting the knowledge
capacity of nomadic life in the post-glacial era
Nomads limited to technology they can carry or fabricate on demand
Accumulating technological knowledge enables more effective use of
smaller geographic areas – growing populations manage more knowledge
Can establish core living areas with permanent goods & structures
Reduced contact with tracks in the broad landscape combined with need
to manage more and more specialized knowledge of technology drives
development of new mnemonic systems
Solution: When songlines no longer suffice, build compact monumental
landscapes that can be traversed sequentially (Kelly 2012 - e.g.,
Stonehenge, Poverty Point, Chaco Canyon Kivas, etc.)
– Early site: Göbekli Tepe ~ 11 kya
southern Turkey 3 ky before the
agricultural revolution
– Many other sites from primary oral
cultures moving from nomadic hunting
and gathering to settled life have
similar monumental structures
47
48. Mnemonics, settlement, the agricultural revolution and increasing
cultural complexity
Current Anthropology 52(S4), Wenner-Gren Symposium: “The Origins of
Agriculture: New Data, New Ideas” (October 2011) reviews in detail the
archeological record of cultural & demographic transitions from nomadic
hunting & gathering to formation of agricultural towns
With settlement, nomadic groups become territorial villages
– The autopoietic entity becomes a socio-technical construct comprised of
people, their linguistically mediated communication networks, their knowledge,
their technologies and their built environment
Positive feedback drives ever-increasing growth rate of cultural
knowledge accumulation for ever-increasing ecological hegemony over
environmental resources
– Accumulating cultural knowledge enables more efficient/effective control of
local resources
– Surplus resources enables population growth in turn providing more capacity
for cultural memory
– Development of ever more sophisticated mnemonic devices
– Population growth enables more specialization of crafts, trades and guilds able
to accumulate still more varied and detailed knowledge of the world
48
49. Ecological grade shifts result in demographic transitions &
increasing socio-cultural/economic complexity
Mobile hunter-gatherers (~15 – 20 adults in group – say 2-4 families)
– Part-time tool-makers & apprentices (realm of specific tool-making resources and processes
knowledge)
– Organized hunting parties
– Gatherers (also need specialized geographic & natural history knowledge)
– Temporary shelter construction, child-minding, fire tending, food processing & preparation
– Extended social and knowledge networks around annual/seasonal meeting places to access
additional mating opportunities, exchange of knowledge & barter limited trade goods
Settled foragers (~ 40 adults in community – say 8 families) require more knowledge
– Knowledge & skill to make specialized tools kept for occasional use full-time tool-making
– Widely ranging hunting parties still need to transport butchered products back to home-base
– Gathering and harvesting known seasonal resources becomes locally more intensive
– Building permanent shelters (i.e., houses) & other more specialized structures
– Need to guard and protect increasingly valuable “capital” (community / personal ”property”)
– Establishment of formal trading networks & mnemonic systems for formally preserving, sharing
and exchanging knowledge at a “tribal” level
Production of specialized goods and surplus resources development of formal barter economy
Social norms and knowledge specialties common to the “tribe” of interrelated communities
Sspecialized “cultic” sites on neutral territory away from existing community settlements enabling the
controlled rehearsal, standardization, and sharing of various bodies of knowledge
49
50. Agricultural Revolution extends human control over
animal and plant metabolism
Major techno-ecological transitions
– Hunting herding & corralling husbandry, dairying, cheese-making, tanning,
animal power & transport
– Harvesting, storage, milling, baking & brewing planting tilling & irrigating
– Stone & mud construction brick making & firing pottery & metallurgy
Demographic revolution – egalitarian communities become hierarchically
organized towns (dozens to hundreds of families), tribal regions, & guilds
Revolutionary emergence of new mnemonic and knowledge management
technologies replace demands for memorization for thinking and doing
– Indexing living memory vs representing knowledge with objective symbols
– Reducing the monumental landscape onto tracks fabricated into hand-held objects
– Representing reality with symbolic tokens:
Increasing socio-economic complexity, economic speciation, and
emergence of knowledge-based autopoietic entities at intermediate levels
– Religious orders, trades, guilds, factories, chartered companies, societies
50
51. Printing and the Industrial Revolution, replacing human/animal
motive power, and externalizing storage of knowledge
(560 ya) Rise of printing for recording, replicating and
transmitting knowledge
– Technologies: papermaking, type founding & setting, printing, post-
press, distributing, indexing, book making, curating, etc.
– Scholarly access to large volumes of recorded, knowledge encouraging
testing, accumulating & disseminating more knowledge
Increased literacy and access to tech knowledge fuels innovation
(~ 300 ya) technology replaces animal and human motive power
with inorganic sources
– Mass production of many things, including books
– General literacy, social upheaval, dislocation and rising affluence
– Ecological hegemony over land and sea
– Exponential knowledge growth
Emergence of knowledge-based economic
organizations as autopoietic entities
– personal knowledge vs organizational knowledge51
52. The Microelectronics Revolution and the increasing
externalization and convergence of individual and social cognition
~ 150 ya mechanical and electro/mechanical technologies for corporate/scientific
number crunching & data processing

– invention of transistorized logic circuits
– ~ 43 ya invention of integrated circuit microprocessors and automatic fabrication (Intel
4004 1971)
Moore’s Law & the still continuing hyperexponential growth of processing power
Extending and replacing more and more human cognition
~ 35 ya automated processing, storage, distribution and retrieval of personal and
corporate knowledge. (Wordstar 1979)
~ 22 ya networking knowledge with the World Wide Web (Tim Berners-Lee 1992)
Universal access to the world knowledge base
– ~ 20 ya Mosaic Netscape Navigator 1994
– ~ 16 ya free open-source browsers Mozilla Firefox 1998
– Indexing knowledge for retrieval
~ 14 ya one billion web pages indexed, more than two billion by end of 2000
Last decade provides instant web search, access & retrieval of virtually the entire scientific & technical literature via
Google Scholar/research library subscriptions
Majority of all English language book titles scanned, indexed, and available (if out of copyright), with smaller fractions

organizational knowledge
59. A reminder
Socio-technical
organizational system =

technology +
organizational knowledge
– Organizational knowledge
What individual members
know about the org.
Explicit knowledge held,
managed in and accessed via
technology owned by the
organization
Knowledge embodied in
organizational structure and
operating routines
Individuals may belong to more than one organization at a time
More knowledge supports more complexity and adaptive capacity
Selective processes also work at organizational level
– Competition and survival
– Lateral and temporal transfer of cultural knowledge59
