Now, scientists have uncovered more of the range of the Denisovans, says Diyendo Massilani of the Max Planck Institute in Germany. His team turned up evidence the ancient humans occupied a high-mountain cave on the Tibetan plateau, called Baishiya cave. In fact, a monk found a piece of jawbone there in 1980, which has been tenuously linked to the Denisovans. But Massilani and his team have now unearthed more conclusive evidence by sifting through cave sediments, and sequencing the genetic evidence the Denisovans left behind. Further genetic work like this might give scientists more clues where early Homo sapiens first met—and mixed with—the elusive Denisovans.
