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 ...
Those first modern humans that had interbred with Neanderthals and lived alongside them died out completely in Europe 40,000 years ago - but not before their offspring had spread further out into ...
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.
Neanderthals became extinct around 40,000 years ago. Hypotheses on the causes of the extinction include violence, transmission of diseases from modern humans which Neanderthals had no immunity to, competitive replacement, extinction by interbreeding with early modern human populations, natural catastrophes, climate change and inbreeding depression.
NEW YORK (AP) — Neanderthals and humans likely mixed and mingled during a narrow time frame 45,000 years ago, scientists reported Thursday. Researchers analyzed ancient genes to pinpoint the time period, which is slightly more recent than previous estimates for the mating.
The findings suggest that very early human history was complex, and modern humans likely interacted with Neanderthals — and other types of archaic humans, including the enigmatic Denisovans ...
Compared with modern humans, Neanderthals had a more robust build and proportionally shorter limbs. Researchers often explain these features as adaptations to conserve heat in a cold climate, but they may also have been adaptations for sprinting in the warmer, forested landscape that Neanderthals often inhabited.

Homo antecessor may be a common ancestor of humans and Neanderthals. [40] [41] At present estimate, humans have approximately 20,000–25,000 genes and share 99% of their DNA with the now extinct Neanderthal [42] and 95–99% of their DNA with their closest living evolutionary relative, the chimpanzees.
