Scientists find the world's oldest ever DNA in Greenland

For more:

Scientists in Greenland announced Wednesday they had found DNA dating back two million years – the oldest ever extracted – in sediment from the Ice Age, opening a new chapter in paleogenetics. The study, led by Danish scientists at the University of Copenhagen, was published in the journal Nature on December 7. The researchers' work, which began in 2006, has made it possible to paint a new portrait of the region two million years ago – a forested environment with mastodons, reindeer and hares running around. The discovery is forcing researchers to reconsider the adaptability of species because two million years ago, Greenland experienced temperatures 11 to 17 degrees Celsius higher than those of today.

This isn't the world's oldest DNA -- it's not even the oldest DNA from that part of the world. Mummified wood from a 45-million-year-old semi-tropical forest on northern Canada's Axel Heiberg Island was sequenced by genetic researchers at the National University of Altai in Russia, and found to be almost identical to the DNA of modern woody plants.
