By piecing together the genetic information locked inside a frozen, fossilized bone, scientists have deciphered the complete genome of an extinct prehistoric horse that roamed the Yukon more than 700,000 years ago. The work rewrites the evolutionary history of the horse and smashes the previous record for the oldest complete genome ever sequenced. In doing so, it redefines how far back in time scientists can travel using DNA sequences as their guide....
