New Genetic Study Challenges Views of Neanderthal Decline
A new genetic study of late Neanderthals from Belgium and France is reshaping how researchers understand the final chapters of Neanderthal history in northwestern Europe.
The study analyzed genetic data from 27 Neanderthal individuals who lived less than about 52,500 years ago, including remains from several archaeological sites in the Meuse Basin of Belgium and nearby regions of France. This area contains a dense concentration of Middle Palaeolithic sites, making it an important region for studying late Neanderthal populations shortly before their disappearance.
One of the key achievements of the research was the sequencing of a high-coverage genome from a roughly 45,000-year-old Neanderthal individual from Goyet in Belgium. The results showed that many of the Neanderthals from Belgium and France were more closely related to one another than to other late Neanderthals known from other parts of Europe. This suggests that they formed part of a regional population with notable genetic connections.
The findings also challenge the idea that all late Neanderthal groups lived in very small and isolated communities. Unlike some Neanderthals from the Altai region, the northwestern European individuals did not show strong genetic signs of mating among close relatives. This points to larger or better-connected groups, at least in this part of Europe.
The study also found no evidence of recent gene flow from early modern humans into these late Neanderthal genomes, even though Neanderthals and modern humans overlapped in Europe during this period. This contrasts with early modern human genomes, which often contain Neanderthal ancestry. The result adds another layer to the complex history of contact between the two human groups.
Importantly, the researchers did not find evidence that genetic deterioration increased over time among these late Neanderthals. Measures of genetic load and diversity did not support the idea that a progressive loss of genetic health was the main driver of Neanderthal disappearance.
Overall, the study presents a more complex picture of late Neanderthal life in northwestern Europe. Rather than being uniformly isolated and genetically declining, some groups appear to have been regionally connected and genetically diverse. The results show how ancient DNA can refine our understanding of Neanderthal populations, their movements, and the circumstances surrounding their final period in Europe.
