The Botai and the WSHG can be modeled as deriving ancestry primarily from an EHG-like and ANE-like source, with some gene flow from an AEA-like population. This model can be simplified into modeling the Botai and the WSHG to derive their ancestry from the combination of an EHG-like population and a population similar to the early Tarim mummies ...
Conversely, significant rates of modern human gene flow into Neanderthals occurred—of the three examined lineages—for only the Altai Neanderthal (0.1–2.1%), suggesting that modern human gene flow into Neanderthals mainly took place after the separation of the Altai Neanderthals from the El Sidrón and Vindija Neanderthals that occurred ...
Central Asian autosomal DNA geneflow was estimated as around 10%. [27] Using haplogroups that are only found in Central Asia, the study estimated Central Asian paternal and maternal contributions. Paternal contribution was estimated as between 8.5% to 15.6% based on C-RPS4Y and O3-M122 Y-chromosome haplogroups.
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.

Human-mediated gene flow: The captive genetic management of threatened species is the only way in which humans attempt to induce gene flow in ex situ situation. One example is the giant panda which is part of an international breeding program in which genetic materials are shared between zoological organizations in order to increase genetic ...
It is further argued that haplogroup E is of Asian origin and that the haploid diversity of haplogroup E supports a strong Eurasian male gene flow. The authors conclude that this supports an Asian origin and may also explain signals of small percentages of Neanderthal DNA found in northern and some western Africans. [24]
Virtually all modern Central Asian MtDNA M lineages seem to belong to the Eastern Eurasian rather than the South Asian subtypes of haplogroup M, which indicates that no large-scale migration from the present Turkic-speaking populations of Central Asia occurred to India. The absence of haplogroup M in Europeans, compared to its equally high ...
They further propose that "the high incidence of R1* and R1a throughout Central Asian and East European populations (without R2 and R* in most cases) is more parsimoniously explained by gene flow in the opposite direction", [250] which according to Sahoo et al. (2006) explains the "sharing of some Y-chromosomal haplogroups between Indian and ...
