In a genomic study encompassing more than 300 genomes, researchers determined the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,000 years — until Neanderthals began to disappear. That interbreeding left Eurasians with many genes inherited from our Neanderthal ancestors, which in total make up between 1% and 2% of our genomes today. Neanderthal man. Image credit: Mauro...
