  • About 2% of our genes are shared with Neanderthals.
  • But some populations have slightly more Neanderthal in them, and it has been puzzling scientists. 
  • By looking at how human genomes' evolved, scientists hope to understand the history of Neanderthals' sexual conquests.

Most of us have a little bit of Neanderthal DNA.

Far from being the lumbering brutes that we once thought they were, a slew of recent studies suggest Neanderthals not only interacted with Homo sapiens, but also had children with them.
