In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) is the most widely accepted model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).
The first is the Out-of-Africa or Recent African Origins hypothesis (Fig. 1). This hypothesis states that modern humans and modern human behavior evolved in Africa and then spread from Africa around 60,000 years ago, replacing archaic hominins with restricted amounts of inbreeding (Fig. 1).
