In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) is the most widely accepted model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).
The Out of Africa theory is the most widely accepted explanation for the origins of modern humans. The theory states that all humans originated in Africa and that we subsequently migrated out of the continent over time. This theory is supported by a variety of evidence, including genetic studies, fossil records, and archaeological finds.
The “Out of Africa” hypothesis is an evolutionary theory of modern human origin that posits that modern humans arose in the late Pleistocene, about 100,000–200,000 years ago, in Africa.
Apr 21, 2016 · The replacement, or out of Africa (OoA), model proposes a single and relatively recent transition from archaic hominins to AMH in Africa, followed by a later migration to the rest of the world, replacing other extant hominin populations. 7, 11 – 15 Under this model, these hominins were driven to extinction, so that most of the ...
The multiregional hypothesis states that independent multiple origins (Model D) or shared multiregional evolution with continuous gene flow between continental populations (Model C) occurred in the...
It advances and empirically establishes the hypothesis that, in the course of the exodus of Homo sapiens out of Africa, variation in migratory distance from the cradle of humankind in East Africa to various settlements across the globe affected genetic diversity and has had a long-lasting hump-shaped effect on the pattern of comparative ...
Aug 8, 2007 · All the ancestors of contemporary Europeans apparently did not migrate out of Africa as previously believed. According to a new analysis of more than 5,000 teeth from long-perished members of...
Jul 18, 2007 · The new data support the single origin, or "out of Africa" theory for anatomically modern humans, which says that these early humans colonized the planet after spreading out of the continent...
Out of Africa 1 contends that earlier Homo species did in fact migrate from Africa before the evolution of H. sapiens. Out of Africa 2 (also called the population replacement hypothesis) picks up where Out of Africa 1 leaves off. It posits that H. sapiens… Read More
Sep 22, 2009 · The “Out of Africa” hypothesis of modern human origins emerged in the mid-1980s, when paleoanthropologists such as Günter Bräuer in Germany (e.g., ref. 25) and Chris Stringer in the U.K. (e.g., ref. 26) began to point out that, sparse as they were, the earliest fossils that resembled members of our species came from southern ...
