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

Thin stretches of the human X chromosome look oddly empty when you scan for Neanderthal DNA. Geneticists even have a name for the gaps: “Neanderthal deserts.

For years, geneticists have wrestled with a curious absence: many modern people carry Neanderthal DNA, yet large stretches of the human X chromosome are almost empty of it. A new study argues that ...

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

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.

A new study in the journal Science reveals that interbreeding between Neanderthals and humans was strongly sex-biased. This social dynamic explains why Neanderthal DNA is missing from our X chromosome ...

A condition known as Robertsonian translocation occurs when the long arms of two chromosomes join together. The characterization of the fully sequenced and assembled fused chromosomes reveals a common ...

Ancient linkups may have happened more frequently between female humans and male Neanderthals, according to an new genetic analysis.

When a woman becomes pregnant, the outcome of that pregnancy depends on many things - including a crucial event that happened while she was still growing inside her own mother's womb. It depends on ...

Kansas City, MO—September 24, 2025—Open a high school biology textbook, and you’ll see human chromosomes lined up two by two, like socks in a drawer. But in about one out of every 800 people, two ...

It’s a common mistake to think we came directly from the monkeys or chimps you see at the zoo today, […] ...
