Denisovan Dentition and DNA
Mysterious Siberian human cousins were contemporary of Neanderthals
Dr. Bence Viola, from the Department of Anthropology at the University of Toronto, studied the teeth, which are larger than both human and Neanderthal teeth, and suggest the Denisovans were large and robust people. Their DNA, now identified from three individuals living 60,000 years apart, suggests long residence near the cave. It also suggests considerable genetic diversity.
Traces of Denisovan DNA are also found in modern-day Melanesian populations in Papua New Guinea and Australia, suggesting the Denisovans live on today, in the same way European and Middle Eastern derived populations carry Neanderthal DNA.
