First came a flurry of reports, from a Stanford group’s paper in Science, that interbreeding by our H. sapiens ancestors with Neanderthals may have left a good many of us with stronger immune systems. That detail adds to a stream of news in the last year or two that not only Neanderthals are in the human ancestry mix, but that in Siberia a group dubbed the Denisovans, also of near-human nature, seem to have been intimate with some of the first humans to enter their territory.
