  • Modern humans and Neanderthals interbred, leaving Neanderthal DNA in modern human genomes and vice versa.
  • Different people inherit different fragments of Neanderthal DNA, with some regions, like the X chromosome, showing no Neanderthal DNA ('Neanderthal deserts').
  • Research indicates a bias in Neanderthal X chromosomes toward modern human sequences, suggesting selective mating preferences, particularly Neanderthal males favoring modern human females.
  • Genetic incompatibility between modern humans and Neanderthals could arise from separate evolutionary paths, leading to disruptive gene interactions when mixed.
  • Some Neanderthal genes introduced into modern humans may have been selected against due to negative impacts on fitness, while others were lost randomly.
