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. Multiregional evolution holds that the human species first arose around two million years ago ...
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.
This hypothesis is supported by the relatively late date of the arrival of modern humans in Europe as well as by archaeological and DNA evidence. [32] Based on an analysis of 55 human mitochondrial genomes (mtDNAs) of hunter-gatherers, Posth et al. (2016) argue for a "rapid single dispersal of all non-Africans less than 55,000 years ago". By ...
Lahr's research is in human evolution, and ranges across human and hominin morphology, prehistory and genetics. Her early work provided a test of the Multiregional Hypothesis of modern humans origins, and underlined much of the argument against models of regional continuity in traits between archaic and modern humans.

Swimming off the coast of Mexico in the Gulf of California live the few remaining vaquitas on earth. This endangered cetacean is not only the smallest porpoise species, but the most rare.
On Jan. 31, the dad was sentenced to six-and-a-half years in jail, and the mom was sentenced to five years in jail, according to ABC.net.. During the sentencing hearing, Judge Linda Black had ...
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.
