All Denesovians but from different populations.
The Pacific Islanders are the oldest, East Asians next then Siberians and American Indians last at about 15,000 years.(Yup, they're saying Denesovians may have been around as recent as 15k years ago)
23andMe tells people how much Neanderthal ancestry they have. How soon will they be able to measure Denisovan ancestry? (That is assuming that “anatomically modern” Homo sapiens and Denisovans got together and made babies.)
