Humans (Homo sapiens[3][4][5]), the only living members of the genus Homo, are mammals of the primate order originally from Africa, where they reached anatomical modernity about 200,000 years ago and began to exhibit full behavioral modernity around 50,000 years ago.[6] The human lineage diverged from its last common ancestor with the chimpanzee some 5 million years ago in Africa, evolving into the Australopithecines and eventually the genus Homo.[7] The first human species to move out of Africa was Homo erectus, the African variety of which, together with Homo heidelbergensis, is considered to be the immediate ancestor of modern humans.[8][9] Homo sapiens.
