The early northern Africa dispersal took place between 130,000–115,000 years ago.
The first wave took place between 130,000 and 115,000 years ago via northern Africa, An archaic view of hominid evolution, Polygenism, holds that different human peoples had differing origins. From 1984 to 2003, an alternate scientific hypothesis was the multiregional origin of modern humans, which envisioned a wave of Homo sapiens migrating earlier from Africa and interbreeding with local Homo erectus populations in varied regions of the globe.According to Kuhlwilm and his co-authors, Neanderthals contributed to modern humans genetically around 100,000 years ago, from humans which split off from other modern humans around 200,000 years ago.According to co-author Ilan Gronau, "This actually complements archaeological evidence of the presence of early modern humans out of Africa around and before 100 ka by providing the first genetic evidence of such populations." The date most commonly attributed to the remains is 67,000 BP.The recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is, in paleoanthropology, the dominant model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).The model proposes a single area of origin for modern humans.
These humans seem to have either become extinct or retreated back to Africa 70,000 to 80,000 years ago, possibly replaced by southbound Neanderthals escaping the colder regions of ice-age Europe.
