As shown in an interbreeding model produced by Neves and Serva (2012), the Neanderthal admixture in modern humans may have been caused by a very low rate of interbreeding between modern humans and Neanderthals, with the exchange of one pair of individuals between the two populations in about every 77 generations.

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.
Two new studies have helped narrow down the time during which Neanderthals interbred with modern humans to a period starting about 50,500 years ago and lasting over seven millennia.. One of the ...
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 ...
Research since 2010 refined the picture of interbreeding between Neanderthals, Denisovans, and anatomically modern humans. Interbreeding appears asymmetrically among the ancestors of modern-day humans, and this may explain differing frequencies of Neanderthal-specific DNA in the genomes of modern humans.
[24] [25] Neanderthals were present both in the Middle East and in Europe, and the arriving populations of anatomically modern humans (also known as "Cro-Magnon" or European early modern humans) have interbred with Neanderthal populations to a limited degree.
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 ...
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.
