“We think based on the DNA sequences that ‘Denisova 2’ is at least 100,000 years, possibly 150,000 years old. Using a different drill bit, she drilled into its root and collected about 10 milligrams of material, which contained DNA. PhotoAfter sequencing the DNA she compared genetic information from the sample with genetic data already collected from Denisovans, Neanderthals and modern humans. He said the genetic study was something the team most likely could not have done five years ago without destroying the tooth. The study also suggests that the species had less genetic variability than modern humans, but more genetic diversity than seen in Neanderthal nuclear DNA.
