Figure 2. Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia (long chronology, single source model). The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. [1]
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]
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 ...
The Neanderthal DNA found in modern human genomes has long raised questions about ancient interbreeding. New studies offer a timeline of when that occurred and when ancient humans left Africa.
The numerous hominin sites in the Levant, such as Ubeidiya and Misliya cave, are used as indicators of this migration route. [ citation needed ] As of 2012, the genetic analysis of human populations in Africa and Eurasia supports the concept that during the Paleolithic and Mesolithic periods, this route was more important for bi-directional ...
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.
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.

Its ancestry is thought to be species related to Aegyptopithecus, Propliopithecus, and Parapithecus from the Faiyum, at around 35 mya. [26] In 2010, Saadanius was described as a close relative of the last common ancestor of the crown catarrhines, and tentatively dated to 29–28 mya, helping to fill an 11-million-year gap in the fossil record.
