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 (red, Out of Africa II), with the numbers of years since they appeared before present. Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus.
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]
It explains the evidence for the theory of early human migrations out of Africa and subsequently around the world, supporting the Out of Africa Theory. This theory claims that all modern humans are descended from anatomically modern African Homo sapiens rather than from the more archaic European and Middle Eastern Homo neanderthalensis or the ...
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".
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.
The Real Eve: Modern Man's Journey Out of Africa is a popular science book about the evolution of modern humans written by British geneticist Stephen Oppenheimer. The book is largely based on the "out of Africa" theory of human origins. Oppenheimer uses information from various disciplines including genetics, archaeology, anthropology and ...
