This document provides an overview of human evolution. It discusses that genetic studies show primates diverged from other mammals around 85 million years ago. Around 15-20 million years ago, the family Hominidae diverged from gibbons. Evidence for human evolution comes from fossils and DNA analysis, with fossils showing early hominins like Sahelanthropus tchadensis dating back 7 million years. Tool use is a sign of intelligence and may have stimulated brain expansion in human evolution.

Human evolution by martin
Human evolution is the evolutionary process leading up to the appearance of modern humans. It is the process by which human beings developed on Earth from now-extinct primates. It involves the lengthy process of change by which people originated from apelike ancestors. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, ethology, evolutionary psychology, embryology and genetics. Scientific evidence shows that the physical and behavioural traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

It then describes several early hominin species like Australopithecus afarensis and Homo habilis. Key developments discussed include bipedalism, brain growth, and basic tool use. The document also notes the emergence and spread of Homo erectus and later species like Homo neanderthalensis and Homo sapiens.
Evolution of man(palaeontological evidence)
This document summarizes the evolution of man from early hominins to modern humans based on paleontological evidence. It outlines the key stages in human evolution including Ramapithecus, Austrolopithecus, Cro-Magnon man, and Homo sapiens. The document presents the taxonomic classification of humans and discusses anatomical changes like posture and brain evolution that occurred at different stages of human evolution over approximately 6 million years.
THE STORY OF HUMAN EVOLUTION
The document provides an overview of human evolution from early hominids to modern humans. It discusses that hominids diverged from apes around 8 million years ago. Early hominids such as Australopithecines, Homo habilis, and Homo erectus developed increasingly advanced tools and technology. Homo sapiens emerged around 200,000 years ago, with Neanderthals present until around 30,000 years ago when they were replaced by Cro-Magnon humans. It also summarizes the transition to more settled agricultural lifestyles during the Neolithic period around 10,000 BCE. Key adaptations that differentiated humans from apes included bipedalism, increased brain size, changes in
Human evolution
Human evolution began in Africa approximately 6-7 million years ago with early hominins that walked upright but had small brains, possibly resembling chimpanzees. Key developments included increased brain size, bipedalism, and tool usage. Australopiths from 2-4 million years ago exhibited the first full bipedalism. Species like Australopithecus africanus had more human-like hands and teeth but brains only a third of modern humans. The earliest evidence of the human lineage Homo dates to around 2.5 million years ago in Africa.
An article on human evolution
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.
3. Human Evolution
- The document discusses human evolution from early primates to modern humans. It describes key developments like bipedalism, increasing brain size, use of tools and fire, and cultural evolution.
- Early primates like tarsiers, lemurs, and lorises evolved around 58 million years ago. Monkeys emerged around 35 million years ago and the first hominids around 6 million years ago.
- Adaptations for tree-dwelling included grasping hands and feet, stereoscopic vision, and long limbs. Bipedalism evolved in early hominids like Australopithecus as an adaptation for life on the ground.
Human evolution
1. Human evolution began with early hominins like Australopithecus that evolved around 4 million years ago in Africa.
2. Key early humans in the genus Homo include Homo habilis, Homo erectus, and Homo neanderthalensis.
3. Homo sapiens emerged around 200,000 years ago in Africa and is the only surviving human species today.
Humans and other primates
Most scientists agree that humans, apes, and monkeys share a common ancestor based on evidence from fossils that show traits of both humans and apes. Primates first evolved from mouse-like mammals and include humans, apes, monkeys and lemurs. While chimpanzees are humans' closest living relative, the earliest hominids showed the ability to walk upright and had smaller teeth, flatter faces and larger brains than other primates. Over time, hominids such as Australopithecines, Homo habilis and Homo erectus appeared with increasingly advanced traits and tool usage, until only Homo sapiens exist today.

Humanorigins 140309074812-phpapp01.ppt
This document summarizes key aspects of human origins, including the evolution of hominids from primates in Africa over 7 million years ago. It describes characteristics of early hominid species like Ardipithecus ramidus and Australopithecus afarensis that began bipedal walking. The first humans of the genus Homo appeared with Homo habilis and had larger brains and tool use. Later Homo species like Homo erectus and Homo heidelbergensis dispersed from Africa and Neanderthals evolved in Europe before modern humans arose in Africa around 200,000 years ago.
Human Evolution
This document discusses human evolution and the timeline of early hominids. It begins by exploring basic questions about human origins and ancestry. It then examines the earliest hominid fossil sites in Africa dating back 6-7 million years, including Sahelanthropus tchadensis from Chad dated to nearly 7 million years old. While the evolutionary relationships between early hominids is still debated, most evidence suggests humans diverged from chimpanzees around 5-7 million years ago. Upright posture evolved in hominids before large brain size. Later sections explore the classification of primates and traits that distinguish hominids from other groups.
Evolution of man
The document summarizes human evolution from early hominids to modern humans based on paleontological evidence. It describes how humans originated from ape-like ancestors in Africa between 4-5 million years ago. Fossils of early hominids like Australopithecus, Homo habilis, Homo erectus provided evidence that humans evolved to walk upright and have larger brains and tools. Later hominids such as Neanderthals and Homo sapiens exhibited fully modern human traits and behaviors like use of fire and complex tools. The document traces the taxonomic classification of humans and provides an overview of the major stages in human evolution.
Human Evolution
1) Lucy, discovered in 1974 in Ethiopia, was an early human species known as Australopithecus afarensis that lived 3.2 million years ago.
2) Though Lucy had characteristics similar to chimpanzees like a small brain and long arms, analysis of her knee and pelvis showed she routinely walked upright, placing her firmly in the human family.
3) Darwin's theory of evolution proposed that humans evolved from earlier species and are simply another form of animal, descended possibly from apes. The development of bipedalism in early humans allowed the hands to be used for other activities like using tools.
Climate (presentation #3 biology l2 project)
Climate is defined as the average weather conditions in a particular region over a long period of time. A region's climate is generated by interactions between the atmosphere, hydrosphere, cryosphere, land surface, and biosphere. Climate classification methods can focus on the causes of climate or the effects. Climate change refers to variations in climate over time, from decades to millions of years, while global warming is the current rise in average global temperatures, primarily due to human-caused greenhouse gas emissions.
Earth´s inner and outer core (Presentation #1 Biology L2 project)
The document discusses Earth's inner and outer core. The inner core is a solid ball of iron, nickel, and other elements with a radius of 1,220 km located at the center of Earth. It was discovered in 1936 by Inge Lehmann using seismic waves. The temperature of the inner core is around 5,700 K and pressure is between 330 to 360 gigapascals. The outer core is a liquid layer of iron and nickel around 2,266 km thick located above the inner core and below the mantle. Convection in the outer core generates Earth's magnetic field, which protects the planet from solar winds.

The evolution of living things
The document discusses evolution and natural selection. It defines key terms like adaptation, species, population and describes how fossils and comparing anatomy provide evidence of evolution. Charles Darwin developed the theory of natural selection to explain how evolution occurs through inherited traits that aid survival being preserved and passed on, with beneficial mutations accumulating over generations to form new species. The process of speciation and examples like finches on the Galapagos Islands illustrate how natural selection can lead to the formation of new species over time.
History and formation of the Earth (Presentation #2 Bilogy L2 project)
The Earth formed 4.54 billion years ago from a solar nebula. Its early atmosphere was toxic and volcanic activity and asteroid impacts were common. One large impact is believed to have formed the Moon. Over billions of years the planet cooled and developed tectonic plates and a stable crust allowing liquid water and the first life. The atmosphere gradually gained oxygen as photosynthetic life evolved. Multicellular life diversified in the Phanerozoic Eon starting over 500 million years ago, though many species died out in extinction events like the one that ended the Cretaceous Period.
DNA for Grade 12
DNA is made of three molecules: sugars, phosphates, and nitrogenous bases. These molecules bond together to form nucleotides, which link up in two chains that spiral into the iconic DNA double helix structure. DNA contains the genetic code and is found coiled tightly in chromosomes in the nucleus of cells. It can make copies of itself through a process called DNA replication that uses the base-pairing rules to produce two identical DNA molecules from one original.
The layers of the earth
The Earth is composed of several layers including the crust, mantle, outer core, and inner core. The crust is made up of various rocks and underlies the mantle, which is a dense, highly viscous layer between the crust and outer core. The outer core extends to around 3000 miles beneath the surface and consists of super-heated liquid molten lava, mostly iron and nickel. Below the outer core is the solid inner core extending another 900 miles inward made up of mostly solid iron and nickel.
Human evaluation
This document describes the key characteristics of several early human ancestors from Ardipithecus ramidus 4.4 million years ago to Homo sapiens (modern humans) from 120,000 years ago, noting their distinguishing physical traits such as brain size and locomotion as well as the time periods and locations where the first fossils were discovered for each species. Overall it traces the evolution of early humans from more chimpanzee-like features to the development of upright walking and increasingly larger brains and sophisticated tool usage.
Evolution of man
Neanderthals were the first human species identified by scientists in 1856. They evolved to be adapted to cold environments with short, stocky bodies. Neanderthals cared for sick and injured members of their group, and evidence suggests they had basic medical knowledge and engaged in cultural practices like painting. Cro-Magnons, found in France in 1868, were early modern humans who made burial art, fire-based hunting techniques, and ceremonial practices. Homo sapiens, emerging around 300,000 years ago, had larger brains and more sophisticated culture and technology, including advanced stone tools, musical instruments, shelters, and burial rituals, representing more complex cognition and symbolism.
Human Evolution Interactive Powerpoint Presentation
The document provides an overview of human evolution and the major species in our family tree, including Homo, Australopithecus, and Paranthropus genera. It describes five Homo species, four Australopithecus species, and three Paranthropus species. Each species entry includes its scientific name, date range, and key distinguishing characteristics. The document is an interactive learning resource for students to learn about early human ancestors and how they fit within our evolutionary tree.
Lesson 1 - 'Layers of the Earth' PowerPoint
The document describes the four main layers that make up the interior of the Earth: the crust, mantle, outer core, and inner core. It provides details on the composition and characteristics of each layer, including their varying temperatures and materials. Specifically, it notes that the crust is the outermost solid layer, the mantle makes up 84% of the Earth's volume and flows slowly, the outer core is a liquid layer of molten iron, and the inner core is a solid ball of iron alloy.

Human Evolution.pptx
This document provides an overview of human evolution. It discusses how humans are classified within the animal kingdom and fall under the Hominidae family along with apes. The document outlines some of the key events in human evolution, such as humans descending from primitive ape ancestors between 200,000-300,000 years ago and acquiring the ability to speak around 50,000 years ago. It also discusses paleontological evidence that is used to investigate the biological and cultural aspects of early humans, including artifacts, fossilized bones, and the environments in which specimens are found.
Evolution from apes to humans, s. mubasher
The document discusses human evolution from a common ancestor with apes. It provides details on:
1) Humans and apes evolved from a common ancestor millions of years ago, though this ancestor was not identical to modern chimpanzees or apes.
2) Early humans like Australopithecines evolved traits like bipedalism, while Homo habilis began using simple tools, and Homo erectus was migratory.
3) The closest living relatives to humans are chimpanzees and bonobos, with human DNA being 98.4% identical to chimpanzees. Molecular evidence suggests gorillas and chimpanzees split from the human line between 8
Anthropology and oral health
https://userupload.net/69zxggv1yww1
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.
Human evolution
Human evolution began with the last common ancestor of all life and tracks the evolutionary history of primates and the genus Homo. Key developments included primates diverging from other mammals 85 million years ago, the publication of Darwin's On the Origin of Species in 1859 which argued for evolution by natural selection, and the discovery of many fossil intermediates in East Africa in the 1960s and 1970s by paleoanthropologists like Louis and Mary Leakey. Bipedalism is considered a major anatomical adaptation in human evolution and the evidence comes from fields like fossils, genetics, and DNA analysis.
Hominid 2
Human evolution occurred over millions of years through a series of gradual changes from early hominid species like Sahelanthropus tchadensis around 7 million years ago to modern Homo sapiens. Key stages included Australopithecus afarensis that lived 2.9-3.9 million years ago, Homo erectus that used tools around 1.8 million years ago, and Homo sapiens neanderthalensis that lived 400,000 to 40,000 years ago. Traits like bipedalism, increased brain size, tool use, and reduced jaws differentiated human species from early primate ancestors over this long period of evolutionary change.
human evolution.pptx
Human evolution did not occur directly from apes but rather from a common ancestor we shared approximately 6 million years ago. While we share over 90% of our DNA with chimpanzees and gorillas, they are actually distant cousins rather than direct ancestors. Additionally, less than half of the human body, about 43%, is made up of human cells - the rest consists of bacteria, viruses and fungi that make up the microbiome. Finally, while Darwin popularized the theory of evolution, some of his other ideas about differences between racial groups and intelligence have been disproven.

Evolution of Homo sepiens
Human evolution began about 6 million years ago in Africa and involves changes that occurred over many generations in early human populations. Key developments included bipedalism, increasing brain size, use of tools, and the emergence of Homo sapiens around 300,000 years ago in Africa. The study of human evolution uses evidence from fossils, genetics, and other scientific disciplines to understand these anatomical and physiological changes.
Neanderthal Vs Homo Sapien Theory
This document discusses theories about human evolution, including the evolution of Homo sapiens from earlier species like Homo habilis and Homo erectus. It describes some of the key anatomical changes that distinguish Homo sapiens, such as bipedalism, larger brain size, and differences in dental structure. The document also references debates about whether Homo sapiens evolved recently in Africa or evolved simultaneously in different parts of the world from Homo erectus populations that migrated out of Africa.
Understanding Our Past
1) Anthropologists study prehistory by examining physical remains and artifacts from early humans and their ancestors. They investigate periods before written records to understand how people lived.
2) Early human ancestors like Ardipithecus ramidus lived 4-5 million years ago in Africa. Australopithecines like Lucy lived 3 million years ago. Homo habilis 2.6 million years ago was the first to make tools.
3) Homo erectus emerged around 2 million years ago, were the first upright walkers, and migrated from Africa to Asia and Europe. Modern humans, Homo sapiens, emerged around 250,000 years ago in Africa and eventually replaced Neanderthals

Homo Sapien Human Evolution
- Charles Darwin proposed that human evolution took millions of years rather than thousands. Evolutionary theory suggests humans evolved from primates like monkeys and apes.
- Researchers have determined chimpanzees are humans' closest living relative, though humans evolved to walk upright on two legs, developed larger brains and became larger in size.
- Fossils like "Lucy" provide insight into early hominids like Australopithecus that showed traits of both apes and humans and used basic stone tools. Later species like Homo habilis and Homo erectus evolved even larger brains and more advanced tool usage.
Human evolution
Human evolution began approximately 7 million years ago and progressed through four main stages. The first modern humans appeared around 200,000 years ago in Africa. Several theories examine the relationship between environmental conditions and human evolution. Key human adaptations include bipedalism, larger brain size, and reduced sexual dimorphism between males and females. Neanderthals were a separate but related species that engaged in interbreeding with modern humans before going extinct.
Researchproject humanevolutioniii-110722152715-phpapp01
The document summarizes key aspects of human evolution from early hominids to modern Homo sapiens. It discusses that the evolutionary history of hominids is not clear due to incomplete fossil records. Early hominid species included Australopithecus afarensis and Homo habilis. Later species such as Homo erectus showed adaptations for walking and larger brain size. The document compares physical traits between hominid species and modern humans. It also addresses debates around the emergence of modern humans and their relationship to Neanderthals.
Human Evolution Essay
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.
Hominid Evolution
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
Essay On Human Evolution
This document provides an overview of human evolution from early hominids to modern humans. It discusses key species in human evolution such as Australopithecus, Homo habilis, Homo erectus, and Homo sapiens. The document also addresses how environmental changes influenced diet and the development of traits like bipedalism and larger brain size over millions of years. Finally, it notes the importance of understanding human evolution and history for modern psychologists in contextualizing human behavior and cognition.
Similarities Between Chimpanzees And Chimpanzees
The document discusses theories of human evolution and the fossil Australopithecus afarensis, nicknamed "Lucy". It provides context on the debate between creationism and evolution, and examines evidence from Lucy's fossil remains, which are considered one of the most complete fossils of an early hominin. However, some dispute the classification of Lucy as a "missing link" in human evolution. The document explores both sides of the debate over Lucy's role as evidence for evolution from apes to humans.
Man Origin.pptx
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.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Human evolution (presentation #4 biology l2 project)
- 1. Human evolution Presentation #4 Juan Sebastian Rodríguez Cubillos Biology L2 Project 9-A
- 2. Introduction: • Is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life, the topic usually covers only the evolutionary history of primates, in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of hominids (or "great apes").
- 3. Genetic studies: • Genetic studies show that primates diverged from other mammals about 85 million years ago in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. The family Hominidae diverged from the Hylobatidae (Gibbon) family 15-20 million years ago, and around 14 million years ago, the Ponginae (orangutans), diverged from the Hominidae family.
- 4. Charles Darwin: • The possibility of linking humans with earlier apes by descent became clear only after 1859 with the publication of Charles Darwin's On the Origin of Species, in which he argued for the idea of the evolution of new species from earlier ones. Darwin's book did not address the question of human evolution, saying only that "Light will be thrown on the origin of man and his history".
- 6. Evidence: • The evidence on which scientific accounts of human evolution is based comes from many fields of natural science. The main sources of knowledge about the evolutionary process has traditionally been the fossil record, but since the development of genetics beginning in the 1970s, DNA analysis has come to occupy a place of comparable importance.
- 7. Evidence from molecular biology: • The closest living relatives of humans are bonobos and chimpanzees (both genus Pan) and gorillas (genus Gorilla).With the sequencing of both the human and chimpanzee genome, current estimates of the similarity between their DNA sequences range between 95% and 99%
- 9. Evidence from fossils • There is little fossil evidence for the divergence of the gorilla, chimpanzee and hominin lineages. The earliest fossils that have been proposed as members of the hominin lineage are Sahelanthropus tchadensis dating from 7 million years ago, Orrorin tugenensis dating from 5.7 million years ago and Ardipithecus kadabba dating to 5.6 million years ago.
- 11. Use of tools: • The use of tools has been interpreted as a sign of intelligence, and it has been theorized that tool use may have stimulated certain aspects of human evolution, especially the continued expansion of the human brain. Paleontology has yet to explain the expansion of this organ over millions of years despite being extremely demanding in terms of energy consumption.
- 12. A sharp rock, an Oldowan pebble tool, the most basic of human stone tools:
