multiregional evolution
|
The multiregional hypothesis holds that the evolution of humanity throughout the Pleistocene (the Historical Epoch from 1.8 million to 10,000 years ybp) has been within a single widespread human species, Homo sapiens, in response to the normal forces of evolution: selection, mutation, genetic drift, and gene flow.

Replacement evolution
|
According to both genetic and fossil evidence, anatomically modern humans evolved solely in Africa, between 200,000 and 100,000 years ago, with members of one branch leaving Africa by 60,000 years ago and replacing all earlier human populations such as Neanderthals, Homo floresiensis and Homo erectus.
