Interbreeding with Archaic Humans Outside Africa

Neanderthals and Denisovans are the closest extinct ancestors of modern humans. High-quality genome sequence is now available from both and has revealed multiple instances of admixture between these archaic hominins and the ancestors of currently living humans. We are using these data to refine the demographic models describing recent human evolution and to detect selective sweeps that post-dated our split from Neanderthals and Denisovans.
