Pieces of bones in a cave in the Tibetan highlands have given researchers new evidence of the mysterious human ancestors known as Denisovans. International researchers examined more than 2,500 bones found inside Baishiya Karst Cave. Most of the bones were from animals hunted by the Denisovans. The scientists studied proteins found in the bones to learn more about the Denisovans and the animals they depended on for food. Baishiya Karst Cave is at a high altitude, or height above sea level, of 3,280 meters in the Tibetan Plateau. The researchers discovered that the Denisovans hunted many different kinds of animals for food including sheep and a large, hairy animal called a woolly rhinoceros. The scientists published their findings this month in Nature.
