Berkeley scientists just generated a pristine genome sequence of Neanderthal DNA—the most complete ever created—and what they found might gross you out. It might also blow your mind.
The DNA sequence came from a 50,000 year old Neanderthal bone, a woman's toe to be exact. The scientists compared it with DNA from modern humans as well as Denisovans, the Neanderthals' contemporaries and often their lovers too. The analysis revealed a new level of complexity in the family tree that connects Neanderthals, Denisovans and a recently discovered mystery human species with modern man.
