The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis, is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution.
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.
Weidenreich pioneered the Polycentric (multiregional) hypothesis, which proposed that human populations have evolved independently in the Old World from Homo erectus to Homo sapiens sapiens, while at the same time there was gene flow between the various populations.
The hypothesis necessarily rejects the assumption of an infertility barrier between ancient Eurasian and African populations of Homo. The hypothesis was controversially debated during the late 1980s and the 1990s. [119] The now-current terminology of "recent-origin" and "Out of Africa" became current in the context of this debate in the 1990s ...
The hypothesis that there has been archaic line in the ancestry of present-day Africans that originated before the San, Pygmies and East African hunter gatherers (and the Eurasians) is supported by a line of evidence independent from the Skoglund findings based on long haplotypes with deep divergences from other human haplotypes including ...

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.
