At least now we know why the Neanderthals “died out” — they were “integrated!”
I’ll make a wild guess that, besides the Denisovans (they showed up in my DNA as well, I was surprised to say the least) and the “Hobbits”, there will probably be further discoveries, that’s just a consequence of going out and looking for them. It’ll be great when, in what will probably be a very few years, the Erectus genomes start to emerge from their remains. Human variety emerged from isolation, which concentrated randomly inherited chromosomes, and give or take mutaions.
