Bipedal Hominins Evolution

Humans became a species when the hominins biologically separated from the ancestors of modern chimpanzees. This separation occurred about seven million years ago. Evidence found in Chad shows that hominins were bipedal, walking upright on two legs. Hominins were able to compete with other primates by taking advantages of the perks of being bipedal. The origin of bipedalism is still a highly debated topic. Remains of australopithecines, earliest bipedal hominins, were found in Ethiopia. These findings gave scientists enough evidence to state that australopithecines lived at least 4.4 million years ago. Hominins that were able to make tools were discovered in 1960. These type of hominins lived near a lake. The scientist who discovered these hominins…show more content…
Everyone in today’s society has at least one ancestor who lived in Africa 150,000 to 200,000 years ago. Once Homo sapiens developed their own language, they were able to work more efficiently, create their own culture, and form social communities. They also had an instrument that would make sounds and each sound had its own meaning. Home sapiens were able to be innovative as a species because of language. Homo sapiens made objects that had symbolic meaning. Our ancestors were able to expand their territorial range over thousand of miles in every type of ecological zone because of their brainpower to adapt to each zone. A small number of humans inhabited an area that is today in Israel. They were also able to cross the Red Sea and settle the Arabian Peninsula. Humans that lived in Southeast Asia were able to make it to Australia. Humans colonized Europe after Australia because of the uninviting cold climate. Homo sapiens migrated to the Americas from northeastern Asia by crossing the Bering Strait and making it to Alaska. Once they made it to Alaska, humans migrated south and then eventually to the eastern side of North America. The human population increased from around 10,000 to 300,000 and this increase led to migration. Homo sapiens, Neanderthals, and the Denisovans lived together but Homo sapiens outlived Neanderthals and the Denisovans because Homo sapiens were more advanced. Even though the genes of all humans are 99.9 percent identical, the 0.1 percent is what accounts for the variation in
