Compared with other world groups, the DNA of Melanesian populations carries some of the largest percentage of ancestry from now-extinct Neanderthals and Denisovans. A genomic study of Melanesians suggests that certain genetic variants inherited from archaic human-like species may have helped these modern people adapt to their tropical island environment.
