The human race origins
1. Early primates evolved adaptations like opposable thumbs and binocular vision to thrive in trees. They divided into prosimians and anthropoids, with the latter including monkeys, apes and humans.
2. The hominid Australopithecus afarensis, including the famous fossil "Lucy", showed evidence of walking upright 3.5 million years ago, even though its brain was chimp-sized.
3. Several hominid species evolved after A. afarensis, with Homo habilis having larger brains and making tools, and Homo erectus spreading across Africa, Asia and Europe around 1.5 million years ago.
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

Population Distribution
Population distribution is influenced by both physical and human factors. Physical factors like climate, landforms, resources, and vegetation determine whether an area is densely or sparsely populated. Areas with extreme climates or hostile environments tend to be sparsely populated, while temperate areas and places rich in resources see higher population densities. Human factors also impact population distribution, as economic opportunities, social preferences, and political stability can encourage or discourage large populations in certain areas.
Human evolution
Dryopithecus, which lived 16-7 million years ago in Europe and Asia, was an early ape-like ancestor of humans. Ramapithecus, which became extinct 7 million years ago, displayed both ape-like and early human-like features such as smaller canines and larger molars. Australopithecus africanus, dating to 4-5 million years ago in South Africa, showed evidence of bipedal locomotion and living both in trees and on the ground. Homo habilis, from 2 million years ago in Africa, used tools and is believed to have lived in family groups and cared for young. Homo erectus, dating to 1.7 million

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
Human evolution began with early hominids like Proconsul that lived 20 million years ago. Early humans included Australopithecines like Lucy that walked upright 3.9-3 million years ago. Genus Homo emerged around 2.5 million years ago including Homo habilis and Homo erectus. Neanderthals lived in Europe 200,000-24,000 years ago before being replaced by modern humans with globular brains and flatter faces 130,000-90,000 years ago.
Human evolution notes
- The earliest known pre-humans were the Australopithecines, which lived in Africa around 3-4 million years ago. They were bipedal but had brains only slightly larger than chimpanzees.
- Later species like Homo habilis and Homo erectus had larger brains and used basic stone tools. Homo erectus was the first to leave Africa, spreading across Asia and Europe.
- Neanderthals emerged in Europe around 300,000 years ago and used advanced Mousterian tools made of flint. They buried their dead and may have used language.

Human Evolution
This document provides an overview of primate and hominid evolution from early primates to modern humans. It describes key developments such as the evolution of binocular vision and grasping limbs in early primates. Important hominid species discussed include Australopithecus, Homo habilis, Homo erectus, Neanderthals, Homo floresiensis, and Homo sapiens. Adaptations to bipedalism and expanding brain size in hominids are highlighted.
Cultural Geography
Here are some key concepts about the growth of language shown through the development of the English language:
- Languages evolve and change over time as they come into contact with other languages and cultures through things like migration, trade, conquest, etc. Old English was transformed into Middle English by Norman French influences after the Norman conquest.
- Languages diffuse from their origin as their speakers migrate and settle new lands, spreading the language with them. English diffused from Britain to its colonies around the world.
- A language may take on new prestige and importance based on political, economic or cultural factors. As the British Empire grew, so did the global influence and spread of English.
- The core vocabulary and grammar of a language remains intact
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.
Paleozoic era cenozoic-Geomorhology Chapter
The document summarizes key events and developments during the Cenozoic Era from 66 million years ago to the present. During this era, mammals evolved and diversified after the extinction of the dinosaurs. Giant mammals and oversized birds lived during the early Cenozoic before going extinct. Flowering plants spread widely. The continents continued separating and mountain building occurred due to volcanic activity associated with rifting. Periodic ice ages began in the Pleistocene, causing extinctions of many large mammals near the end of that epoch.

Biogeography
This document provides an overview of biogeography, which is the study of the distribution of species across different regions. It discusses the history of biogeography, with Alfred Russel Wallace seen as the "Father of Biogeography" for his early research. There are three main types of biogeography: historical biogeography focuses on origins and extinctions of taxa; ecological biogeography examines current distributions based on environmental interactions; and conservation biogeography works to protect environments. The document also describes different terrestrial and aquatic biomes across the world, highlighting their defining characteristics, climates, plants, and animals.
The Paradigms of Geography
The document discusses the concept of paradigms in geography. It defines a paradigm as a set of beliefs and assumptions that shape how one views reality in a particular field. It notes that major paradigm shifts have occurred in geography, such as Ptolemy's geocentric model being replaced by Copernicus' heliocentric model. The document outlines several paradigms that have influenced geography, such as the romantic analytical paradigm of early geographers like Ritter and Humboldt, and the political geography paradigm associated with the rise of nation states. It also mentions that geography currently lacks complete revolutions and paradigms shifts, but different schools of thought are seeking new paradigms to better understand geographical regions.
Evolution of Human
The document summarizes human evolution from early primates to modern humans. It describes how primates evolved from tree-dwelling mammals around 65 million years ago. Early hominids like Australopithecus began walking upright around 3-5 million years ago. Several early Homo species evolved, including H. habilis, H. erectus, and H. heidelbergensis. Homo sapiens evolved in Africa around 200,000 years ago before migrating to other parts of the world. Neanderthals were a closely related species that lived in Europe and Asia.
Anthropology
Human evolution is a gradual process that has occurred over a long period of time. Key stages included Dryopithecus, which is considered the common ancestor of apes and humans around 25 million years ago. Ramapithecus and Kenyapithecus, dated to between 12-5 million years ago, displayed traits that were ancestral to humans. Australopithecus, the first upright walking species around 4 million years ago, had a brain capacity of around 500cc. Homo habilis began making tools around 2.4 million years ago. Later species such as Homo erectus had larger brains and used fire. Homo sapiens emerged around 200,000 years ago, with modern humans
Definition, Evolution and approaches of cultural geography.
Cultural geography is the study of culture and its relationship to place. It examines how cultures are distributed across space and how places and identities are produced. Cultural geography analyzes cultural values, practices, expressions, and artifacts, as well as cultural diversity and plurality. It considers how people make sense of places and develop a sense of place. Cultural geography focuses on cultural components like religion, language, architecture, and more, and how they differ around the world. It aims to understand the relationship between humans and their environments. Cultural geography developed from the work of Carl Sauer at UC Berkeley and emphasizes qualitative analysis over quantitative methods. Today, it includes specialized fields like feminist geography and urban geography.
Geological time scale
The document summarizes the geological time scale which divides Earth's history into different eras, periods, and epochs based on fossil and stratigraphic evidence. It describes the four eons of Earth's history starting with the Hadean and Archean eons of the earliest lifeforms like bacteria. It then outlines the major eras - Paleozoic, Mesozoic, and Cenozoic - describing some of the significant lifeforms, events, and environmental changes that occurred during each period within these eras. The largest unit of the geological time scale is the eon, while the smallest is the epoch.
Earth crust
The document describes the four main layers of Earth: crust, mantle, outer core, and inner core. The crust is the thinnest layer and is divided into continental and oceanic crust. Below the crust is the mantle, which makes up over 80% of Earth's volume and is composed of iron-rich rock. Within the mantle are the lithosphere and asthenosphere layers. The outer core is liquid, while the inner core is solid due to extreme pressure. Seismic waves have helped scientists determine the composition of Earth's layers.
Major extinction events
- An extinction event is a widespread decrease in biodiversity where the rate of extinction increases compared to the rate of evolution of new species. The "Big Five" mass extinction events are the five largest extinction events in Earth's history.
- The document then describes each of the "Big Five" extinction events by time period, percentage of families/genera/species that went extinct, and possible causes. The largest was the Permian-Triassic extinction about 252 million years ago where up to 96% of marine species went extinct.
- Possible causes of mass extinction events discussed are large igneous provinces (flood basalts), sea level falls, asteroid/comet impacts, and global cooling, with flood basalts
Chapter 6 Cultural Geography
The document discusses various topics related to cultural geography including what culture is, how cultures change and diffuse, and theories about cultural evolution and diffusion. It also discusses global diffusion of Western culture and current perceptions of American culture. Cultures are learned and shared systems of symbols, behaviors and meanings that are passed down within societies. Cultures can change internally through technological developments or externally through processes of cultural diffusion and acculturation between societies.
Milestone of human evolution
Charles Darwin was an English naturalist whose theory of evolution by natural selection became the foundation of modern evolutionary studies. He formulated his theory privately in 1837-1839 after returning from a voyage aboard the HMS Beagle, and published On the Origin of Species in 1859, which has deeply influenced Western society and thought. Primates including humans evolved from earlier species like Australopithecus afarensis, which lived 3.85-2.95 million years ago in Eastern Africa and had characteristics of both apes and humans. Later species such as Homo habilis, Homo erectus, Homo neanderthals, and Homo sapiens exhibited increasingly human-like traits and behaviors as they adapted to
Biology
There is no consensus on the evolutionary history of hominids due to an incomplete fossil record. This presentation will provide a brief overview of hominid evolution from the beginning of life in the Tertiary period to modern Homo sapiens. While the exact timeline is uncertain, evidence suggests early hominids like Australopithecus emerged around 4-5 million years ago in Africa. Traits like reduced canine teeth and bipedalism developed over time. Later species such as Homo habilis and Homo erectus had larger brains and more human-like features. Anatomically modern humans are believed to have evolved around 200,000 years ago in Africa.

Early humans evolved in Africa over 5 million years ago from forest-dwelling primates. The earliest known hominid is Ardipithecus, which lived 4-5 million years ago. Later hominids included Australopithecus, Homo habilis, Homo erectus, and Homo sapiens. Homo erectus was the first to leave Africa, migrating to Europe and Asia around 1.8 million years ago. Modern humans, Homo sapiens sapiens, evolved in Africa around 200,000 years ago and migrated worldwide by 10,000 BCE, replacing Neanderthals.GROUP-3-UCSP.pptx
Evolution is a process that results in changes that are passed on or inherited from generation, which help organisms survive, reproduce, and raise offspring. These changes become common throughout a population, leading to new species.
Biological evolution explains how all living things evolved from a single common ancestor, but any two species may be separated by millions or billions of years.
This species was bipedal, fully erect, and capable of grasping tools and weapons with its forearms. These fossil specimens have a larger brain size of 600 cubic centimeters (37 cubic inches), as well as a jaw and tooth size more akin to modern humans.
-Fossil skulls contain tangible evidence of unequal brain development, which is mirrored in the way stone tools were formed.
-The earliest of our ancestors to show a significant increase in brain size and also the first to be found associated with stone tools
Unit 6_Human Evolution_Complete.pptx
1. Several hominin species evolved in Africa over millions of years, including Australopithecus afarensis, Homo habilis, and Homo erectus.
2. Homo erectus was the first hominin to migrate out of Africa, spreading across Asia and Europe between 1.8 million to 100,000 years ago.
3. Neanderthals evolved in Europe and western Asia between 250,000-30,000 years ago before going extinct, while modern humans emerged in Africa around 200,000 years ago.
Human Evolution
1. Several hominin species evolved in Africa over millions of years, including Australopithecus afarensis, Homo habilis, Homo erectus, and Homo heidelbergensis.
2. Homo sapiens emerged around 200,000 years ago in Africa before migrating to Asia and Europe, where they encountered species like Homo floresiensis and Homo neanderthalensis.
3. Key adaptations that emerged over time included bipedalism, increased brain size, tool use, and modern human behaviors and capabilities.
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

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.
Unit 5 prehistory theory
Prehistory is divided into three main periods - the Palaeolithic, Neolithic, and Metal Ages. The Palaeolithic, which began over 2 million years ago, saw the emergence and evolution of early humans from primate ancestors in Africa. Key hominid species that developed over this time include Homo habilis, Homo erectus, Homo antecessor, Neanderthals, and Homo sapiens. Neanderthals and Homo sapiens existed side by side in Europe for thousands of years before Neanderthals went extinct. The Neolithic began around 9000 BC when early humans adopted agriculture and settled in villages. During the Metal Ages beginning around 5000 BC, humans began using
Life And Discoveries Of Louis Leakey
Louis Leakey was a pioneering British archaeologist and anthropologist who, along with his wife Mary, made several important discoveries regarding human evolution in East Africa. Some of their key findings included discovering fossils of early hominids like Zinjanthropus boisei and Homo habilis that supported the "Out of Africa" theory of human evolution. Leakey also established research sites at Olduvai Gorge in Tanzania that yielded many significant fossil finds. Despite facing setbacks, Leakey's work in East Africa in the mid-20th century helped prove the "Out of Africa" model of human origins.
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.
Study of Human evolution
This document discusses human evolution and key species in the human lineage. It begins by defining evolution and describing how characteristics are passed down and vary within populations. It then summarizes the emergence of key hominin species like Australopithecus, Homo erectus, Neanderthals, and Homo sapiens. For each species, it highlights traits like brain size, locomotion, and anatomical features of the skull, jaws and teeth. It also provides context on the geographic distribution and time period for each species.
Evolution and charles darwin
The document provides information about human evolution and the theory of evolution. It discusses key topics like the two main theories of evolution proposed by Darwin and Lamarck. It also summarizes the major human ancestors throughout different eras like Australopithecus, Homo habilis, Homo erectus, and Homo sapiens. Physical evidence and discoveries that have helped support the theory of evolution are also briefly outlined.
