Humans interbred with Neanderthals despite being classified as distinct species
Extensive paleogenomic research confirms that anatomically modern humans interbred with Neanderthals during their migrations, leaving measurable amounts of Neanderthal ancestry in the genomes of non-African populations today.
The claim is specific and empirical, dealing with paleogenomics and human evolution. The retrieved papers consistently provide strong genetic evidence demonstrating that modern humans and Neanderthals interbred, despite their traditional classification as distinct species. Therefore, the balance verdict is SUPPORTED.
