For her birthday, the husband of one of my friends here at the library gave her a complete genetic profile from the company 23 And Me. Among the findings: she is 2.7 % Neandertal. There's nothing like being able to trace your ancestry back 70 to 80 thousand years.
She is going to check to see if there are any genes linking her to the Denisovan group. They may or may not have included that information.
