When the two species got together tens of thousands of years ago, the hookups may have often involved a male Neanderthal and a female human, according to a new study. The findings, described February ...
A 2026 study finds sex-biased interbreeding, not genetic incompatibility, likely explains why Neanderthal DNA is scarce on the human X chromosome.
If more human females mated with Neanderthal males than the other way around, over thousands of years you would expect to see ...

Perhaps human females found Neanderthal males to be high-status providers. Or perhaps Neanderthal society was “patrilocal” — meaning women moved to join the man’s family — while human society was the ...
Learn how sex-biased interbreeding between Neanderthals and modern humans explains why Neanderthal DNA is largely missing ...
