Greenland Polar Bear

Caption

This image shows a polar bear in March 2011 on Kap Tobin, Scoresby Sound, Central East Greenland. Polar bears diverged from brown bears less than 500,000 years ago, rapidly evolving a metabolism that allows them to subsist on a high-fat diet and obtain water by burning fat.
