Proponents of the multiregional hypothesis believe the combination of regional continuity inside and outside of Africa and lateral gene transfer between various regions around the world supports the multiregional hypothesis. However, "Out of Africa" Theory proponents also explain this with the fact that genetic changes occur on a regional basis ...
In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the most widely accepted [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens). It follows the early expansions of hominins out of Africa, accomplished by Homo erectus and then Homo ...
Roberts then explores an alternative to the Out of Africa theory, the multiregional hypothesis that has gained support in some scientific communities in China. According to this theory, the Chinese are descended from a human species called Homo erectus rather than from the Homo sapiens from which the rest of humanity evolved.
By the early 2000s, the majority of scholars supported the Out of Africa hypothesis, [66] [67] according to which anatomically modern humans left Africa about 50,000 years ago and replaced Neanderthals with little or no interbreeding. Yet some scholars still argued for hybridisation with Neanderthals.
Milford Howell Wolpoff is a paleoanthropologist and professor of anthropology at the University of Michigan and its museum of Anthropology. He is the leading proponent of the multiregional evolution hypothesis that explains the evolution of Homo sapiens as a consequence of evolutionary processes and gene flow across continents within a single species.
Monogenism or sometimes monogenesis is the theory of human origins which posits a common descent for all humans. The negation of monogenism is polygenism.This issue was hotly debated in the Western world in the nineteenth century, as the assumptions of scientific racism came under scrutiny both from religious groups and in the light of developments in the life sciences and human science.
The tests of the Out of Africa hypothesis conducted by Hawks et al. (2000) and Wolpoff et al. (2001) focused on what these authors evidently considered to be the main prediction of the hypothesis, namely, that there should be no genetic ontinuity or interbreeding between early modern humans and archaic hominids in Europe, East Asia, and ...
Relethford's research focuses on human population genetics and the evolutionary origin of modern humans. [1] For example, he has proposed his own version of the "Out of Africa" model, the standard theory for the evolution of modern humans; he has described his model as placing human origins "mostly out of Africa".
