The woman lived 20 thousand years earlier than other denisovans.
According to the researchers, the tooth is likely to be the second a molar of the lower jaw and belongs to a child of 10-12 years. Genetic analysis of nuclear DNA showed that it was a girl, and the analysis of mitochondrial DNA have substantially extended our knowledge on the genetic diversity of the population of denisovans. It was comparable to modern, for example, European populations of people. If we assume that the accumulation of mutations in Denisova occurred at roughly the same rate as modern humans, that the girl lived 20 thousand years before he lived the owner of the tooth of last notes (Denisova 8), which is considered the earliest known of the denisovans. That, in turn, older than the others, apparently, not less than 60 thousand years. Radiocarbon analysis of the remains of the younger tells about the age about 50 thousand years.
If we consider all uncertainties and approximations, it is still possible now to say that the denisovans have inhabited the territory of Altai for at least a hundred thousand years. Scientists note that their overall genetic diversity could therefore be more than the diversity of modern populations in real time. Perhaps they were relatively small groups that impoverishes their gene pool. In addition, scientists are yet there is evidence just about four individuals who lived in the same cave, so that new findings can increase their understanding of this subject.
