A horse you can't ride
HELSINKI, FINLAND- Scientists deciphered the genetic code from a horse about 700,000 years old and did it using a tiny fossil bone found in the frozen Yukon. That's nearly ten times older than any other animal that has had its genome mapped. The horse was probably the size of current Arabian horses. Scientists used new techniques and computing to map DNA from a five-inch fossil fragment. The work was published in the journal Nature and discussed at a science conference in Finland. The Danish researchers say the new techniques they used could make it possible to map the genetic blueprint of all sorts of ancient animals from early humans to mastodons and mammoths.
