Dr. Willerslev's team found DNA in the Kolyma skull as well. A small fraction of that individual's ancestry came from Ancient North Siberians. But most of it came from a new population. Dr. Willerslev and his colleagues call them the Ancient Paleo-Siberians.
The DNA of the Ancient Paleo-Siberians is remarkably similar to that of Native Americans. Dr. Willerslev estimates that Native Americans can trace about two-thirds of their ancestry to these previously unknown people.
One reason that the Ancient Paleo-Siberians were unknown until now is that they were mostly replaced by a third population of people with a different East Asian ancestry. This group moved into Siberia only in the past 10,000 years — and they are the progenitors of most living Siberians.
