The Regional Continuity Model (RCM), its clearing suggesting that local populations in Europe, Asia and Africa continued their indigenous evolutionary development from pre modern Middle Pleistocene forms to anatomically modern humans. With regards to the multi-regional continuity model of human evolution, there is without a doubt a preponderance of fossil data that supports the diverse origins of Homo sapiens in different regions of the globe. Skulls displaying a wide variety of mixed modern and archaic features have been found in every corner of the world. The mere existence of these fossils is evidence enough to prove that human evolution was far less cut-and-dried a process than the advocates of the replacement model of human evolution would like to suggest, and, in fact, rather astonishingly complex. Through the gene flow and natural selection, according to the multiregional hypothesis, local populations would not have evolved totally independently from one another. The multiregional answers that question(1) denying that the earliest modern H. sapiens populations originated in Africa and question (2) asserting that significant levels of gene flow ( “migration” ) between various geographically disperse premodern populations were extremely likely throughout the pleistocene.

Replacement Models (RM), emphasizes that all modern humans first evolved in Africa and later dispersed to other parts of the globe, where they replaced the hominins already living in other…
