Slimak Rebuts 250,000-Year Neanderthal 'Preference' Claim as Female Mobility Better Fits DNA

Summary
Ludovic Slimak argues the genetic pattern behind headlines about Neanderthal men "preferring" Homo sapiens women does not show attraction, only an uneven inheritance signal that could reflect several mechanisms.
The key evidence is lower Neanderthal DNA on the X chromosome in modern non-Africans, but Slimak says sex-chromosome inheritance and hybrid male fragility can produce that depletion without any partner choice.
At El Sidrón in Spain, remains of 12 Neanderthals showed 3 adult males sharing one maternal lineage while 3 adult females had different ones, supporting a patrilocal system in which women moved between groups.
That social pattern, he says, better explains asymmetry in gene flow and also clashes with a romance narrative because late Neanderthal genomes show no recent Sapiens ancestry, while early Eurasian Sapiens consistently carry Neanderthal DNA.
The broader point is that genes can trace transmission, not reconstruct whether interbreeding reflected alliances, exchange, coercion or conflict, so archaeology and anthropology are needed to interpret Neanderthal-Sapiens contact.
