Were they in contact?

Did they interbreed?

When did they diverge?

For Denny herself, the remaining questions are more personal — or as personal as questions about a 90,000-year-old individual can be.

What was the context of her parents’ meeting?

Did her Neanderthal mother and Denisovan father form a lasting bond, or was their encounter brief?

Did Denny grow up in one community or the other — in a Neanderthal group, in a Denisovan group, or in some mixed community?

Were there other hybrid individuals in the population she was part of?
