The genome of a horse that lived 700,000 years ago in Canada’s Yukon Territory suggests the common ancestor for modern horses, zebras, and donkeys dates to 4 million years ago.
The DNA discovered from the ancient horse is 10 times as old as any DNA retrieved so far, suggesting it may be possible to get genetic information from animals that lived as long as 1 million years ago, according to a study released yesterday in the journal Nature.
