Immune system with genes of the Neanderthals
By studying the genes of DNA that make the immune system researchers have identified the traits that would result from hybridization with Neanderthals and Denisovans enough to allow the body to be able to better resist the virus and external aggressors that may be a potential threat to the health of "sapiens" human, especially that coming as evolutionary history from West Asia. The hybridization would occur in men who left Africa about sixty five thousand years ago since those who not migrated they had do not even a chance to mix their genes. These studies are made complex for the difficulty of aligning the genome of the vary fragments for the paucity of archaeological finds, especially in the case of Denisovans man of which seem to be available only few fragments (a finger and a tooth) unlike for example of the Neanderthal.
