A 2026 study finds sex-biased interbreeding, not genetic incompatibility, likely explains why Neanderthal DNA is scarce on the human X chromosome.
The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia.
Genetic research indicates that Neanderthal and Homor Sapiens interbreeding was socially driven to an unexpected degree.
New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.
Learn how sex-biased interbreeding between Neanderthals and modern humans explains why Neanderthal DNA is largely missing ...
A new study in Science suggests Neanderthal men and modern human women interbred more often than assumed, reshaping theories about our DNA. But what drove those ancient pairings remains uncertain.
Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...
