The Neanderthal DNA found in modern human genomes has long raised questions about ancient interbreeding. ... They determined that the flow of Neanderthal genes into humans occurred roughly 47,000 ...
Further analyses have found that Neanderthal gene flow is even detectable in African populations, suggesting that some variants obtained from Neanderthals posed a survival advantage. [ 25 ] Approximately 20 percent of Neanderthal DNA survives in modern humans; however, a single human has an average of around 2% Neanderthal DNA overall with some ...
The new research estimates an average date for Neanderthal-Homo sapiens interbreeding of about 47,000 years ago, compared to previous estimates that ranged from 54,000 to 41,000 years ago.
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 ...
Scientists, however, have found it surprisingly hard to piece together gene flow in the opposite direction: how intermingling between the two groups may have shaped Neanderthals, who went extinct ...
From the extent of linkage disequilibrium, it was estimated that the last Neanderthal gene flow into early ancestors of Europeans occurred 47,000–65,000 years BP. In conjunction with archaeological and fossil evidence, interbreeding is thought to have occurred somewhere in Western Eurasia, possibly the Middle East. [ 87 ]
Scientists have known since the first Neanderthal genome was sequenced in 2010 that early humans interbred with Neanderthals, a bombshell revelation that bequeathed a genetic legacy still ...
In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.
