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.
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 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 ...
Neanderthals and Denisovans are more closely related to each other than they are to modern humans, meaning the Neanderthal/Denisovan split occurred after their split with modern humans. [ 14 ] [ 47 ] [ 93 ] [ 113 ] Assuming a mutation rate of 1 × 10 −9 or 0.5 × 10 −9 per base pair (bp) per year, the Neanderthal/Denisovan split 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.
Previously it was found that about 20% of the Neanderthal genome was found in modern Eurasians, [20] but the figure was also estimated at a third. [21] A 2023 study found an introgression from modern humans to Neanderthals around 250,000 years ago, and estimated that roughly 6% of the Altai Neanderthal genome was inherited from modern humans. [22]
Since modern human/Neanderthal admixture is known to have occurred in the Middle East, and no modern body louse species descends from their Neanderthal counterparts (body lice only inhabit clothed individuals), it is possible Neanderthals (and/or modern humans) in hotter climates did not wear clothes, or Neanderthal lice were highly specialised.
Slimak determined that this particular Neanderthal lived 42,000 years ago, towards the end of that species’ time on this planet. As such, he named the Neanderthal Thorin after the Tolkien character.
