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 ...
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.
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 ...
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 ...
They found snippets of Neanderthal DNA that placed the mating at around 45,000 years ago. In a separate study, researchers tracked signs of Neanderthal in our genetic code over 50,000 years. They found Neanderthal genes related to immunity and metabolism that may have helped early humans survive and thrive outside of Africa.
This could explain the reason why no modern man has a Neanderthal Y chromosome. [40] In October 2023, scientists reported that an anatomically-modern-human-to-Neanderthal admixture event occurred roughly 250,000 years ago, and also noted that roughly 6% of the Altai Neanderthal genome was inherited from anatomically modern humans.

Over this 7,000-year time frame, early humans encountered Neanderthals, had sex and gave birth to children on a fairly regular basis. The height of the activity was 47,000 years ago, the study ...
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.
