Web30 dec. 1999 · According to the multiregional model of human evolution, archaic humans originated in Africa, migrated throughout the Old World over a million years ago, and then evolved into modern form multiple times in different areas of the Old World, with enough gene flow between these regions to prevent speciation [ [1] ]. WebThe extent of archaic assimilation in living humans remains modest, and fossil evidence outside of Africa shows little sign of the long-term morphological continuity through to recent humans expected from the multiregional model. Thus, rather than multiregionalism, a recent African origin (RAO) model for modern humans is still supported by the ...
