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 ...
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.

Homo sapiens emerges in Africa before about 0.3 Ma from a lineage closely related to early H. heidelbergensis. [29] The first wave of "Out of Africa II and "earliest presence of H. sapiens in West Asia, may date to between .3 and 0.2 Ma, [29] and ascertained for 0.13 Ma. [30]
Polygenism is a theory of human ... with the monogenic "Out of Africa" hypothesis and ... Colenso pointed to monuments and artifacts in Egypt to debunk monogenist ...
The published conclusion was that all current human mtDNA originated from a single population from Africa, at the time dated to between 140,000 and 200,000 years ago. [14] The dating for "Eve" was a blow to the multiregional hypothesis, which was debated at the time, and a boost to the theory of the recent origin model. [15]
The theory was proposed in 2004 by Dennis Stanford of the Smithsonian Institution and Bruce Bradley of the University of Exeter. [1] However, according to David Meltzer , "[f]ew if any archaeologists—or, for that matter, geneticists, linguists, or physical anthropologists—take seriously the idea of a Solutrean colonization of America."
How is monkeypox spread? What caused the 2022 outbreak? Here is a look at the myths versus the facts surrounding the monkeypox virus according to health officials.
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.
