items typically food over large distances. Humans evolved from the groups of “homo” meaning the same. About 2-3 million years ago Homo Habilis adapted from the original Australopithecines with a 50% larger brain. The Homo Habilis chipped flakes off the ends of volcanic rock to be used as tools. Thus‚ they were able to eat a greater variety of nutritious food increasing their mental capacity. About a million years ago the Homo Erectus adapted with a 1/3 larger brain than the Habilis. They were scavengers

Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation‚ including species‚ individual organisms and molecules such as DNAand proteins.[1]All life on earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological

“Decoding Neanderthals” Neanderthals are an extinct species shown as our ancestors.They began to disappear 40‚000 years ago as Homo sapiens came on the scene. They are a branch of the human family tree and are considered to have been primitive with no verbal language. Many believe them to have a lack of intelligence but science is proving the theory wrong. History shows Neanderthals as undeveloped humans‚ but the possibilities of their lifestyle being more advance than the lifestyle of modern

The article "Finding Lucy: The Leakeys and the Search for Human Origins" dated June 13‚2016 written by Cynthia Stokes Brown discusses the Leakeys and their finding‚ but also Donald Johanson finding Lucy. Now‚ most scienctists agree that the human (Homo sapien) chain started out in Africa. They thought that because when they tested the ashes of the fossils that were buried by ashes near volcanoes‚ they could see how old the fossils were. The fossils that the scientists found were up to 4.4 million

phases of the evolution to modern humans—Homo habilus and Homo erectus‚ for example‚ are two stages of the transformation to Homo sapiens‚ the species that all modern humans belong to. According to the Hardy-Weinberg theorem‚ evolution will only not occur under very rigid circumstances‚ and since those circumstances do not apply to humans‚ the species is continuing to evolve‚ and is very likely to develop into an entirely new species eventually—perhaps Homo aquaticus‚ humans that will live underwater

first theory might be more credible‚ both theories to this day are still being debated over the study of human origins due to new research being found over the years. To begin‚ the Multi-regional theory is how Homo erectus left Africa (the Old World) about 2 million years ago to become Homo sapiens in all different parts of the world. In the reading‚ “The Multiregional Evolution of Humans”‚ authors Thorne and Wolpoff analyze how this representative would ever come to reason with some solutions to

Introduction to Hominid Evolution Hominid evolution is the theory of the origins of the human species (Homo sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)

find out how modern humans evovled (Marks‚ 2012). There are many models of how Homo saipan evolved. The Multiregional Continuity Model suggests that Homo erectus left Africa and moved into the Middle East‚ Europe‚ and Asia. Then these different groups evolved simultaneously into Homo saipan without direct connection to each other. The other main theory is the Out of Africa Model. This model suggests that Homo saipan evolved in Africa and then migrated into the Middle East‚ Europe and Asia.
