«Right now, the research group is analyzing the nuclear genome the results of which could provide us with information about its relationship with the Neanderthals and about the existence of genomic variations associated with the immune system that accounts for the evolutionary success of Homo sapiens over other human species with whom it co-existed.

Older Homo sapiens made it out of Africa, but these populations must have mostly died out.
