Recent research has uncovered significant insights into the mating habits between Neanderthals and modern humans, revealing that Neanderthal males predominantly mated with Homo sapiens females. DNA analysis suggests that this interbreeding created a clear pattern, contributing to the genetic makeup of contemporary humans. The study indicates that the majority of human DNA inherited from Neanderthals traces back through maternal lineage, correlating with the finding that Neanderthal men often partnered with human women. This unexpected bias in prehistoric relationships sheds light on the ancient dynamics of human evolution and the integration of Neanderthal genes into the human genome.
