Multiregional origin of modern humans
The multiregional hypothesis, multiregional evolution (MRE), or polycentric theory is a scientific model that provides an alternative explanation to the more widely accepted ""Out of Africa"" model for the pattern of human evolution.Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as H. erectus and Neanderthals as well as modern forms, and evolved worldwide to the diverse populations of modern Homo sapiens sapiens. The theory contends that the mechanism of clinal variation through a model of ""Centre and Edge"" allowed for the necessary balance between genetic drift, gene flow and selection throughout the Pleistocene, as well as overall evolution as a global species, but while retaining regional differences in certain morphological features. Proponents of multiregionalism point to fossil and genomic data and continuity of archaeological cultures as support for their hypothesis.
