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 ...
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.
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.
Modern human DNA found in Neanderthal genomes offers clues to how our archaic ancestors disappeared, according to a new study.
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 ...
The plot shows that the Neanderthal ancestry proportion in Africans is correlated with gene flow from Eurasians. For example, knowing that today Eurasians carry ∼2% of Neanderthal ancestry, we observed that East Africans (Ethiopians) had ∼1% Neanderthal ancestry and ∼50% Eurasian ancestry.
Neanderthals lived in a high-stress environment with high trauma rates, and about 80% died before the age of 40. [25] The total population of Neanderthals remained low, and interbreeding with modern humans tended toward a loss of Neanderthal genes over time. [26] They lacked effective long-distance networks.
