Why did Neanderthals likely go extinct?
One model postulates that habitat degradation and fragmentation occurred in the Neanderthal territory long before the arrival of modern humans, and that it led to the decimation and eventual disappearance of Neanderthal populations.
When did Neanderthals go extinct?
40,000 years ago
The spread of modern humans across Europe is associated with the demise and ultimate extinction of Neanderthal populations 40,000 years ago, likely due to competition for resources.
When & How did Neanderthals become extinct?
Scientists broadly agree that the Neanderthals died out about 40,000 years ago, after a wave of modern humans migrated out of Africa about 20,000 years earlier. What remains unclear is why the Neanderthals died out and what role, if any, our ancestors had in the act.
Why did the Neanderthals and Denisovans go extinct?
By 10,000 years ago, they were all gone. The disappearance of these species resembles a mass extinction. But there’s no obvious environmental catastrophe — volcanic eruptions, climate change, asteroid impact — driving it.
Why did other humans go extinct?
Climate Change May Have Been a Major Driver of Ancient Hominin Extinctions. A new study suggests at least two close relatives of Homo sapiens may have died out as their environments changed. Others have suggested we may have eaten a more varied diet or were more efficient runners than other hominins.
What does Denisovans look like?
Denisovans resembled Neanderthals in many key traits, such as robust jaws, low craniums, low foreheads, wide pelvises, wide fingertips, and large rib cages. But Denisovans were different than both Neanderthals and modern humans in some important areas.
Did Denisovans and Neanderthals mate?
In Eurasia, interbreeding between Neanderthals and Denisovans with modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans.
When did Neanderthals become extinct?
Replacement of Neanderthals by early modern humans. Neanderthals became extinct around 40,000 years ago. This timing, based on research published in Nature in 2014, is much earlier than previous estimates, and derives from improved radiocarbon-dating methods analyzing 40 sites from Spain to Russia.
What happened to the Neanderthals in the Iberian Peninsula?
Evidence for continued Neanderthal presence in the Iberian Peninsula 37,000 years ago was published in 2017. Various hypotheses on the causes of Neanderthal extinction implicate: failure or inability to adapt to climate change
Can we explain the long-lasting contact zone between modern humans and Neanderthals?

Did Neanderthals contribute to the human genome?
The Neanderthal genome project published papers in 2010 and 2014 stating that Neanderthals contributed to the DNA of modern humans, including most humans outside sub-Saharan Africa, as well as a few populations in sub-Saharan Africa, through interbreeding, likely between 50,000 and 60,000 years ago.
