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 ...
Early human migrations. Putative migration waves out of Africa and back migrations into the continent, as well as the locations of major ancient human remains and archeological sites (López et al., 2015). Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents.
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]
African diaspora. The global African diaspora is the worldwide collection of communities descended from people from Africa, predominantly in the Americas. [48] The African populations in the Americas are descended from haplogroup L genetic groups of native Africans. [49][50] The term most commonly refers to the descendants of the native West ...
Multiregional origin of modern humans. 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 ...
The indigenous people of Africa are groups of people native to a specific region; people who lived there before colonists or settlers arrived, defined new borders, and began to occupy the land. This definition applies to all indigenous groups, whether inside or outside of Africa. Although the vast majority of Native Africans can be considered ...
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period. It includes brief explanations of the various taxonomic ranks in ...
Alleles thought to have originated in Neanderthals and Denisovans have been identified at several genetic loci in the genomes of modern humans outside Africa. HLA haplotypes from Denisovans and Neanderthal represent more than half the HLA alleles of modern Eurasians, [ 45 ] indicating strong positive selection for these introgressed alleles.
