Straight from the horse's toe: The world's oldest genome (via The Christian Science Monitor)

Researchers have sequenced the genome of a horse that lived some 700,000 years ago – the oldest genome ever sequenced – making it possible to reconstruct an evolutionary narrative of the modern horse, whose journey through history has been intimately…

From a tiny fossil bone found in the Yukon, scientists have deciphered the genetic code of an ancient horse about 700,000 years old. The researchers also found new evidence that the endangered Przewalski's horse, found in Mongolia and China, is the last surviving wild horse. Claudia Feh/Przewalski's Horse Association via Nature/AP]
