Recent African origin of modern humans

Theory of early hominid migration

The recent African origin of modern humans or the "Out of Africa" theory (OOA) holds that present-day humans outside Africa descend mainly from a single expansion of anatomically modern humans (Homo sapiens) from Africa about 70,000–50,000 years ago. It is the most widely accepted paleo-anthropological model of the geographic origin and early migration of the human species. This expansion follows the earlier expansions of hominins out of Africa, accomplished by Homo erectus and then Homo neanderthalensis.
