Himalayan Marmots are Revealing How Animals Adapt to Living at Extreme Elevations

How do animals live in the cold, oxygen-starved environments of the high mountains? Himalayan marmots — beaver-ish rodents of unusual size — may have an answer, find scientists who have assembled a complete draft genome of the animal.
