There’s a little bit of Neanderthal in most of us. Neanderthals and Homo sapiens had a long history of intermingling, before the former went extinct about 40,000 years ago. That mixing means most modern humans have some amount of Neanderthal DNA—and it accounts for up to 3% of the genome in some people.While these genetic remnants don’t have much impact on our day-to-day lives, they may be responsible for one surprising effect: pain tolerance. Recent research shows that people with Neanderthal variants in the gene SCN9A have a lower pain tolerance than people without the gene.This isn’t the…
