From EcoNews:
Ancient DNA from Belgium and France challenges the idea that Neanderthals faded away as isolated, increasingly inbred groups. Researchers found signs of connected populations in northwestern Europe, without evidence of an increasing burden of harmful genetic variants.
Neanderthals disappeared roughly 40,000 years ago, but the findings do not explain why. Instead, they challenge a simple story of biological decline, suggesting that the final chapter of Neanderthal life differed across regions rather than following one inevitable genetic downward spiral.
The research examined ancient remains from present-day Belgium and France dating to less than about 52,500 years ago. Nature’s press summary describes 27 remains representing at least 11 distinct individuals, an important distinction because several bone fragments can belong to the same person. (Read more.)
