The findings may reveal new insights into early human mating preferences ...

Researchers found that Neanderthals carried excess modern human DNA on their X chromosomes, pointing to predominantly male ...

The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia.

New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.

A 2026 study finds sex-biased interbreeding, not genetic incompatibility, likely explains why Neanderthal DNA is scarce on the human X chromosome.

DNA evidence suggests homo sapiens women more often paired with Neanderthal men, helping explain why Neanderthal genes are rare.

Geneticists have a better understanding of how prehistoric pairings unfolded, with new research suggesting they were mostly between male Neanderthals and female humans.

Humans don’t have a defined mating season like deer or wolves. Here’s how evolution blended biology, culture and social life into year-round intimacy.

Learn more about mammal monogamy rates, which support the theory that the primary mating pattern in Homo sapiens is monogamy. Many of us think of our own species as a monogamous one. We select a mate, ...
