The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

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 ...
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.
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.
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.
Although it took many years, polygenism, which required species to be created in specific geographic locations and to remain immutable, has been almost entirely replaced among scientists by Darwin's theory of evolution from a common ancestor. Persistent antagonism to Darwinian theory is today primarily a matter of religious or political viewpoint.
Thorne's discovery and reconstruction of "Mungo Lady" led him to question the validity of the "Out of Africa" theory commonly held by many anthropologists. His specimen contained an advanced skull and overall anatomy that resembled modern day humans, but originated during an era and in a location where such hominids were believed not to exist.
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 ...
