700,000 Year Old Horse Becomes Oldest Animal To Have its Genome Sequenced
A genome sequence derived from a 700,000-year-old horse fossil (inset) sheds new light on equine evolution and confirms that Przewalski’s horse (pictured) is indeed genetically distinct from domesticated breeds.

Scientists have sequenced the oldest genome to date—and shaken up the horse family tree in the process. Ancient DNA derived from a horse fossil that’s between 560,000 and 780,000 years old suggests that all living equids—members of the family that includes horses, donkeys, and zebras—shared a common ancestor that lived at least 4 million years ago, approximately 2 million years earlier than most previous estimates. The discovery offers new insights into equine evolution and raises the prospect of recovering and exploring older DNA than previously thought possible…
