Modern Humans: Origin and Evolution

Abstract

Modern humans originated recently in geological time from a diverse African gene pool. Very little if any interbreeding probably occurred with existing archaic human populations outside of Africa such as the Neanderthals of Europe.

Keywords: multiregional model; single recent replacement model; coalescence; Neanderthal; mitochondrial DNA
