From MSNBC.com: Science:
The oldest ever recovered DNA samples have been collected from under more than a mile of Greenland ice, and their analysis suggests the island was much warmer during the last Ice Age than previously thought.
The DNA is proof that sometime between 450,000 and 800,000 years ago, much of Greenland was especially green and covered in a boreal forest that was home to alder, spruce and pine trees, as well as insects such as butterflies and beetles.
From the genetic material of these organisms, the researchers infer that Greenland's temperature once varied from 50 degrees Fahrenheit in summer to 1.4 degrees Fahrenheit in winter — the temperature range that the tree species prefer.
