What I found interesting is that, while any given modern human has no more than about 4% Neanderthal DNA, it isn't the same 4% in everyone. About 20% of the Neanderthal genome is found in humans. I'm not sure what this says about interbreeding.
And then there's the Denisovans... I gotta get my DNA done...
