Keep in mind that the point at which the line of Homo sapiens separated from the Denisovans was about 700,000 years ago, and the Neanderthals 600,000 years ago. This means that modern blacks having from 2% to 19% of the genes of this hominid in 1/5 are hominids. At the same time, Europeans have virtually no hominid genes - theoretically they have a slight taint of Neanderthals, but it is extremely low. Cro-magnon, genetically modern Europeans, whose oldest skeletons are dated at 40,000 years BOTH had no admixture of other hominids.
