[103] [104] Dental remains from the Italian Visogliano and Fontana Ranuccio sites indicate that Neanderthal dental features had evolved by around 450–430,000 years ago during the Middle Pleistocene. [105] There are two main hypotheses regarding the evolution of Neanderthals following the Neanderthal/human split: two-phase and accretion.
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.
The results show that haplogroup D introgressed 37,000 years ago (based on the coalescence age of derived D alleles) into modern humans from an archaic human population that separated 1.1 million years ago (based on the separation time between D and non-D alleles), consistent with the period when Neanderthals and modern humans co-existed and ...
It’s not clear how often humans and Neanderthals mated. And there’s more to be learned about the traits humans got from Neanderthal and Denisovan DNA. Plus, there’s the mysterious ...
Other lineages of ancient humans also went extinct around 40,000 years ago and disappeared just like the Neanderthals ultimately did, said Johannes Krause, director at the department of ...
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 ...

Levantine Neanderthals had phenotypes significantly more similar to modern humans than European Neanderthals (classic Neanderthals). [24] [25] This may be because of gene flow from early modern humans in the Levantine corridor or the fact that the European Neanderthal phenotype is a specialized climatic adaptation.
