Ancient DNA retrieved from the wolf cub’s final meal revealed the tissue belonged to a woolly rhinoceros. Chacón-Duque and his team used the devoured morsel to reconstruct the woolly rhino’s entire genome—the first time scientists have sequenced an Ice Age animal’s complete genome from the contents of another animal’s stomach. They published their findings on Wednesday in the journal Genome Biology and Evolution.
