Danish geneticists have mapped the DNA of a 700,000-year-old horse bone, yielding the world's oldest full genome. National Geographic reports that Ludovic Orlando, an evolutionary geneticist with the Natural History Museum of Denmark, and his team identified key patterns in Equus evolution — the group of animals that include horses, donkeys, and zebras — tracing the genus' ancestry back two million years earlier than it was originally believed to have emerged.
