Researchers have made a new discovery about the European Neanderthals. A study published in Nature reveals that Neanderthals in northwest Europe had more genetic variability than previously thought. This finding has led the authors to question whether a lack of genetic diversity was a cause of their extinction.

The study's results complicate the existing understanding of the Neanderthals' demise. For more information on this research and its implications, readers can refer to the original publication in Nature, as reported by El Mundo.
