Interesting times.
The strains have not been found per se, just the one DNA sample was sequenced from the cave — but the living people carrying Denisovan DNA (including yours truly) have been discerned to be carrying additional otherwise unknown sequences which appear to be from additional, otherwise unknown, Denisovans. I feel so durn smug about this... ;^)
If I’ve not sent the link to the archaic DNA research site (they just want your raw DNA file), let me know, in case you’re interested. There are a BUNCH of archaic DNA samples from all over the place, various ages (including stuff close to the radiocarbon limit) that they test for.
