The multiregional continuity hypothesis
Did you know?
WebThe “Multiregional Theory” is the idea that early hominids, such as H. erectus, and archaic H. sapiens had already populated the world, and independently evolved after already being established in different locations (Ember, Ember, & Peregrine, 2009, p. 163). WebThe multiregional hypothesis states that independent multiple origins (Model D) or shared multiregional evolution with continuous gene flow between continental populations (Model C) occurred...
WebIn contrast, the Multiregional Continuity hypothesis explains that evolution of modern humans occurred regionally and without replacement, meaning that each continent’s archaic H. sapiens gave rise to their own modern H. sapiens individually.

WebThe three materials which disapprove the Out of Africa theory and support the multiregional theory are tools that developed regionally, transitional fossils which indicate interbreeding between Neanderthal and Homo sapiens and DNA studies suggesting an independent emergence from Africa. The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis 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 …
