Genetic studies and fossil evidence show that archaic "Homo sapiens" evolved to anatomically modern humans solely in Africa between 200,000 and 60,000 years ago. Members of one branch of "Homo sapiens" left Africa at some point between 125,000 and 60,000 years ago, and that over time these humans replaced earlier populations of the genus "Homo" such as Neanderthals and "Homo erectus".
