Her genome answered, definitively, the question of whether Neanderthals and Denisovans could interbreed and produce viable offspring.

Yes.

They could.

Here is the proof.

But in answering that question, her genome opened others: How often did such interbreeding happen?

In how many geographic locations did the ranges of Neanderthals and Denisovans overlap sufficiently for such encounters?

Were there other populations — regional variants, intermediate groups, populations that did not fit cleanly into either the “Neanderthal” or “Denisovan” category — whose existence we have not yet detected?

What happened to the descendants of such encounters?
