20 Things You Didn't Know About... Neanderthals

The Natural History Museum, London
The hominids are depicted as degenerate and slouching because the first Neanderthal skeleton found happened to be arthritic. 

1. You’re pretty much a Neanderthal. While it’s been more than 5 million years since we parted ways with chimps, it has been only 400,000 since human and Neanderthal lineages split. 

2. If you’re Asian or Caucasian, your ancestors interbred with Neanderthals as recently as 37,000 years ago, when they crossed paths in Europe. 

3. And that sex had benefits. Inherited Neanderthal genes come in alleles that help fight off nasty viruses such as Epstein-Barr — associated with several kinds of cancer, says Stanford University immunologist Laurent Abi-Rached.
