Human evolution
The document summarizes key differences between pongids (non-human primates) and hominids (early humans and their ancestors). Hominids evolved to walk upright, have longer legs than arms adapted for striding, high foot arches, and reduced teeth and jaw sizes. In contrast, pongids are bent over, have arms longer than legs for swinging, low foot arches, and larger teeth. Hominids also developed larger brain sizes ranging from 400-2000cc compared to 280-705cc for pongids. The document proposes hominid evolution originated in Africa and then migrated outward.

Life sciences grade 12 human evolution
Human evolution began with early bipedal apes in Africa between 5-7 million years ago. Key early species included Australopithecus, which exhibited traits of both apes and humans. Around 2 million years ago, Homo habilis emerged with increased brain size and the ability to make basic stone tools, suggesting more advanced cognition. Bipedalism was a major development, freeing the hands for tasks while making locomotion more efficient. Overall, the document traces major trends in human evolution from early apes to Homo habilis, including the emergence of bipedalism and tool use.
Ch. 15 Hominin Evolution
This document discusses hominin evolution and classification. It begins by classifying humans as mammals within the kingdom Animalia, phylum Chordata, class Mammalia, and order Primates. 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.
Human evolution
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.
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.
Hominids & Skills
Hominids are a group that includes humans and their closest relatives. As the African tropical forest retreated due to the Ice Age, some primates adapted to walking upright on two feet (bipedalism) which allowed them to see further, travel more efficiently, and use their hands. The earliest hominids were called Australopithecines including "Lucy". Later, Homo habilis emerged around 2 million years ago and were the first to make stone tools. Homo erectus also appeared then and were the first to control fire and build more complex tools. Around 100,000 years ago Homo sapiens emerged and migrated out of Africa, developing early signs of culture.

human evolution
This document outlines the timeline of human evolution from early primate ancestors 6 million years ago to modern humans. It describes key species in our evolution like Australopithecus, Homo habilis, Homo erectus, and Homo sapiens. Australopithecus was the first hominin genus to walk upright around 4 million years ago in Africa. Homo habilis evolved around 2.5 million years ago and were the first to use stone tools. Homo erectus emerged around 1.8 million years ago in Africa and was the first hominin to migrate out of Africa. Modern humans, Homo sapiens, evolved in Africa around 200,000 years ago with larger brains and lighter
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.
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.
Anthropology (Human Evolution)
This document lists the major species in the human lineage, starting with Sahelanthropus from 7-6 million years ago and continuing through early Homo species like Homo habilis and Homo erectus to later species such as Homo sapiens and Homo neanderthalensis. It traces human evolution from our earliest ancestors to modern humans through over 20 hominin species spanning several million years.
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.
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
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.
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
The human evolution
Human evolution began with the last common ancestor of all life and covers the evolutionary history of primates and the genus Homo, leading to the emergence of modern humans. The lengthy process of human evolution saw people originate from apelike ancestors over approximately six million years through a series of natural changes including mutation and changes in gene expression that caused adaptation to the environment. Man has been a tribal animal for over four million years in order to cooperate and survive threats through his early bipedal movement.
Anthropoids
Anthropic experts summarize the document as follows:
1. Anthropoids evolved from prosimian ancestors in the Late Eocene and by the Oligocene were well established, divided into three superfamilies.
2. The oldest known hominid, Sahelanthropus tchadensis from Chad dating to 7 million years ago, shows a mosaic of primitive and advanced traits puzzling scientists about its placement in the human family tree.
3. Debate continues on the earliest hominids, with Orrorin tugenensis at 6 million years and Ardipithecus ramidus between 5.8-5.2 million years also potential direct human ancestors, though evidence is incomplete
Tracing the human evolution
The document traces human evolution from primates to modern humans based on fossil and genetic evidence. Key events include:
- Primates diverged from other mammals around 55 million years ago, with the earliest primate fossil dated to 65 million years ago.
- The earliest hominins, like Sahelanthropus tchadensis from 6-7 million years ago, displayed both ape-like and human-like traits.
- Species like Australopithecus afarensis from 3-2.9 million years ago were the first to walk fully upright.
- Homo habilis and Homo erectus, dating back to 2.3 million and 1.8 million years ago respectively
biological and cultural evolution
This document summarizes the biological and cultural evolution of early humans from Australopithecus to Homo Sapiens. It describes biological evolution as genetic changes from generation to generation that are studied through physical remains. Cultural evolution refers to developments in human culture studied through analyzing lifestyle changes. Key hominid categories discussed are Australopithecus, Homo Habilis, Homo Erectus, and Homo Sapiens. Traits like upright walking, increasing brain size, tool use, and shelter building are noted as major developments.
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
Australopithecus
Australopithecus was an early hominin genus that evolved in eastern Africa around 4 million years ago. They stood between 1.2 to 1.4 meters tall and had brains that were about 35% the size of modern humans. Australopithecus was bipedal and ate fruits, vegetables, and tubers. One species of Australopithecus is believed to have evolved into the genus Homo around 2 million years ago in Africa, playing an important role in human evolution.

It then discusses the evolution of great apes including humans' closest relatives chimpanzees. Key human ancestors like Australopithecus, Homo habilis, and Homo erectus are summarized along with debates around early human migration out of Africa. The document concludes with discussions of Neanderthals and anatomically modern humans.
Biocultural Evolution
The document discusses biocultural evolution and early hominids. It describes Darwin's theory of natural selection and how early hominid species like Australopithecus were capable of bipedalism. It then outlines some of the main hominid species, including Homo habilis which used tools for scavenging, Homo erectus which existed around 1.8 million years ago and moved from Africa to Asia, and Homo sapiens which evolved from Homo erectus around 500,000-200,000 years ago.
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.
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
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.
Understanding Culture, Society and Politics - Biological Evolution
This is a powerpoint presentation of one of the Senior High School Core Subject: Understanding Culture, Society and Politics. For this powerpoint, this serves as a presentation about the topic of the definition and timeline of human biological evolution.
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
9 Early Hominins
Early hominins are believed to have diverged from a common ancestor with African apes around 6-7 million years ago. The key difference between early hominins and early apes was that hominins were habitually bipedal while apes were quadrupedal. Bipedalism provided advantages like increased efficiency and the ability to use tools. Traits like the pelvis, femur, spine and foot provide evidence of bipedalism in hominin fossils. While the fossil record is incomplete, discoveries like Australopithecus afarensis help illustrate the evolution of bipedalism before increases in brain size.
The human evolution
This document summarizes the evolution of early human ancestors from 7 million years ago to present day Homo sapiens. It describes several key species including Ardipithecus ramidus, Australopithecus afarensis, Paranthropus boisei, Homo habilis, Homo neanderthalensis, and Homo sapiens. Each species is briefly discussed with details about when and where they lived as well as important traits that linked them to later human ancestors or differentiated them from other species.
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.
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.
Human origins natalia rosalía
Hominids originated in Africa at least 7 million years ago. Early hominid species like Ardipithecus ramidus, Australopithecus anamensis and Australopithecus afarensis displayed characteristics like bipedalism and thicker tooth enamel. Climatic changes forced early hominids to occupy more open savannah areas. Later species like Homo habilis, Homo ergaster and Homo erectus had larger brains and used tools and fire. Homo sapiens originated in Africa around 200,000-160,000 years ago. Neanderthals originated in Europe and disappeared around 28,000 years ago, while Homo sapiens emerged in Europe

1. The document discusses the history and theories of human evolution from early hominids to modern humans. It traces the major species in our lineage and their defining characteristics.
2. Early hominid species like Australopithecus afarensis and Homo habilis exhibited traits like bipedalism and increased brain size compared to apes. Later species such as Homo erectus and Homo heidelbergensis used more advanced tools and mastered fire.
3. Neanderthals and early Homo sapiens inhabited Europe and Asia around 200,000 years ago before modern humans emerged in Africa around 50,000 years ago. Theories of human evolution are constantly reevaluated
Human evolution javier caro
Human evolution began with early hominins like Ardipithecus and Australopithecus around 4-5 million years ago in Africa. Key early species included Australopithecus afarensis like "Lucy" dated to 3.2 million years ago. Later hominins included Homo habilis around 2.4-1.4 million years ago, known for early stone tool use, and Homo ergaster around 1.7-2.5 million years ago in Africa, likely ancestor of later humans. Homo erectus emerged around 1.8-1.3 million years ago in Africa and spread throughout the Old World.
Evolution and charles darwin

During a time of dramatic climate change 200,000 years ago, Homo sapiens evolved in Africa. Like other early humans, they gathered and hunted food, and evolved behaviors that helped them respond to the challenges of survival. “
- 21. “Evolution isn't just a story about where we came from. It's an epic at the center of life itself. Far from robbing our lives of meaning, it instills an appreciation for the beautiful, enduring, and ultimately triumphant fabric of life that covers our planet. Understanding that doesn't demean human life - it enhances it. “ -Kenneth R. Miller
