Further research has shown that the back-migration into the region was a complex process, identifying multiple origins for the Eurasian component in Northeast African groups today. [ 20 ] [ 21 ] A report in November 2015 on a 4,500-year-old Ethiopian genome [ 22 ] [ 23 ] had originally overestimated the genetic influence of the Eurasian ...
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.
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 ...
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.

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.
