  • A new genetic analysis suggests that interbreeding between humans and Neanderthals predominantly occurred between female humans and male Neanderthals.
  • The study, published in the journal Science, found a notable lack of Neanderthal DNA in the human X chromosome, contrasting with more human DNA present in the Neanderthal X chromosome.
  • Researchers propose that this asymmetrical distribution of DNA is best explained by specific mating behaviours, rather than the survival rates of offspring.
  • The findings indicate that whenever Neanderthals and modern humans mated, there was a preference for male Neanderthals and female modern humans.
  • While the precise nature of these ancient interactions remains a mystery, the research underscores the role of behaviour and societal patterns in shaping human evolution.
