The Summary Many people have a tiny slice of Neanderthal DNA, evidence of interbreeding between the species and ancient human ancestors. Two new studies suggest that interbreeding occurred during a limited period of time as ancient humans left Africa. How often did ancient humans and Neanderthals interbreed? Studies published in the journals Nature and Science on Thursday suggest that ancient humans and Neanderthals interbred during a limited period of time as the humans left Africa and migrated to new continents. Then the researchers analyzed changes over time in the distribution and length of Neanderthal DNA in those genomes.
