🔄FROM THE ARCHIVE Our ancestors interbred with Neanderthals, and evidence of these ancient liaisons can still be found in the DNA of people living today.
We all have a little Neanderthal in us. The amount varies a bit, from less than a percent to likely over 2 percent, depending on our heritage. East Asians seem to have the most Neanderthal DNA in their genomes, followed by those of European ancestry. Africans, long thought to have no Neanderthal DNA, wereThat genetic material is the result ofat some point in the past.
Neanderthal genes are thought to be linked to a number of different traits in humans. They might help protect us from some pathogens, for example, but also make us more susceptible to heart disease. Neanderthal DNA probably also plays a role in hair color, our sense of smell and even our sleeping habits, to some extent.
