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. The analysis may provide insight to how we adapt to the cold.

“As one of the highest-altitude-dwelling mammals, the Himalayan marmot is chronically exposed to cold temperature, hypoxia [lack of oxygen], and intense UV radiation,” Enqi Liu of Xi’an Jiaotong U
