At an altitude of nearly 3 miles, the Tibetan plateau is an extreme place to live. It's cold, it's hard to grow food, and there's about 40 percent less oxygen in the air than there is at sea level.

Somehow, though, native Tibetans are adapted to it. Their bodies — and their blood in particular — work differently than those of people used to lower altitudes. The Tibetans' advantage might be thanks to an ancient inheritance.
