 Evolution of African Multiregionalism JENA, GERMANY – According to a report published in The Atlantic an international team of scientists led by archaeologist Eleanor Scerri of the University of New York. Oxford argues that modern humans have emerged at different places in Africa at different times, in a process called "African multiregionalism". These groups of human ancestors developed independently of one another, separated by geographical barriers, until climate change restructured the landscape and brought them closer together. separated them again. This model looks like a river braided together by many water courses sneaking into each other, rather than an evergreen tree with a trunk and several branches. For example, the fossils of 300,000-year-old South Africa and Ethiopia present a complex mix of archaic and modern features. "People at the time seemed more different from each other than people today," says Scerri, "and it's very difficult to answer the question of what a Homo sapiens . But then there was a continental tendency to the modern human form. "Stone tools and other artifacts support this interpretation of the fossil record," she adds.The trend towards more sophisticated tools and other elements is found in Africa, there are about 300,000 years, and has not been traced in a particular area or period.To learn more about our human ancestors, see "Decoding Human Genetics."
