A comparison of the genomes of a Neanderthal who lived 120,000 years ago in Siberia with those from modern humans in sub-Saharan Africa has revealed insight into the migratory and interbreeding history of both species.
According to 23&me, I have 4% of the Neanderthal gene. Sometimes I feel like I've met those who wiped us out long ago. It's just a feeling of caution, like an instinct or something.
