Europe's Late Neanderthals Descended from a Single Group that Survived the Ice Age
A study incorporating fresh DNA data and archaeological evidence has revealed that the last Neanderthals in Europe experienced a massive population turnover. The research shows that late Neanderthals shared a largely uniform gene pool before their final disappearance around 40,000 years ago, descending from a single localized group that survived harsh Ice Age conditions.
The international research team, led by Professor Cosimo Posth at the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen, traced the dramatic genetic history of European Neanderthals. The new study, published in the journal PNAS, indicates that one localized group survived the severe climate by retreating to a glacial refugium in what is now southwestern France approximately 75,000 years ago. The descendants of these resilient survivors then spread across Europe after 65,000 years ago.
Genetically speaking, almost all late Neanderthals descended from this one lineage.
“Our data enabled us to reconstruct geographically that Neanderthals retreated to what is now southwestern France,” explained Professor Posth. “There, around 65,000 years ago, a new population emerged and later spread across the whole of Europe. This explains why almost all Late Neanderthals sequenced so far – from the Iberian Peninsula to the Caucasus – belong to the same line of inherited mitochondrial DNA.”
