Denisovans are a mysterious group of our ancient relatives, unknown until a decade ago, who lived alongside Neanderthals and Homo sapiens. The hominin species is thought to have ranged from Siberia to Indonesia, and many places in between (although some researchers believe the Denisovans could actually be multiple species or groups). When these curious human cousins vanished, they left behind surviving bits of their DNA in living Melanesian and East Asian people, but not much else. So far, the only known Denisovan fossils include just a few teeth, a finger bone and a small fragment from a Russian cave, and a partial jaw found on the Tibetan Plateau.
