Replacement model



A theory proposed by Christopher Stringer and Peter Andrews suggesting that the place of origin of modern human beings is in Africa. Early human predecessors then spread to the various parts of the world, replacing the Neanderthals and other hominids that eventually became extinct.


This theory surmises that the regional anatomical differences of today's modern humans are of recent developments.
