According to the authors Green et al. (2010), the observed excess of genetic similarity is best explained by recent gene flow from Neanderthals to modern humans after the migration out of Africa. [11] They estimated the proportion of Neanderthal-derived ancestry to be 1–4% of the Eurasian genome. [11]
Other research supports a migration out of Africa between about 65,000 and 50,000 years ago. [60] [66] [62] The coastal migration between roughly 70,000 and 50,000 years ago is associated with mitochondrial haplogroups M and N, both derivative of L3.
Studies show that the pre-modern migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appeared to have occupied all of Africa about 150,000 years ago; some members of this species moved out of Africa 70,000 years ago (or, according to more recent studies, as early as 125,000 years ago into Asia, [1] [2 ...
Southern Dispersal migration out of Africa, Proto-Australoid peopling of Oceania. [62] Archaic admixture from Neanderthals in Eurasia, [ 63 ] [ 64 ] from Denisovans in Oceania with trace amounts in Eastern Eurasia, [ 65 ] and from an unspecified African lineage of archaic humans in Sub-Saharan Africa as well as an interbred species of ...
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago.
Major East Eurasian ancestry lineages which contributed to modern human populations include the following: [8] Australasian lineage — refers to an ancestral population that primarily contributed to human populations in a region consisting of Australia, Papua, New Zealand, neighboring islands in the South Pacific Ocean and parts of the Philippines.
In addition to being found to have 8% Asian (as a proxy for Native American ancestry) and 19.6% European ancestry, African-Americans, who were sampled in 2010, were found to be 72.5% African. [40] African Americans were found to be more closely genetically related to Yoruba people than East Africans (e.g., Luhya , Maasai ). [ 40 ]
WSH ancestry from this period is often referred to as Steppe Early and Middle Bronze Age (Steppe EMBA) ancestry. [c] This migration is linked to the origin of both the Corded Ware culture, whose members were of about 75% WSH ancestry, and the Bell Beaker ("Eastern group"), who were around 50% WSH ancestry, though the exact relationships between ...
