Recent research suggests that the interbreeding between Neanderthals and anatomically modern humans at the end of the Ice Age was predominantly characterized by unions between Neanderthal men and Homo sapiens women. This conclusion is surprising, given that modern humans eventually came to dominate and lead to the extinction of Neanderthals over time. Typically, one would expect that the 'winning' population would have more offspring with individuals from the other group, especially in cases of different human ethnicities.

The study's lead author mentioned that this pattern raises intriguing questions regarding the social structures and gender roles of Neanderthals, indicating that there is still much to explore in understanding human evolution. The presence of Neanderthal DNA in modern human genomes points to the significance of these interspecies unions, offering clues into the complexities of human ancestry and the interactions between ancient populations.

Further research is planned to analyze the social dynamics of Neanderthal communities and their relationships with Homo sapiens. Such studies could shed light on the nature of these interactions and their implications for both species, as well as the evolutionary narrative of modern humans and their Neanderthal relatives.
