(Molecular Biology and Evolution (Oxford University Press)) A new study demonstrates strong genetic evidence that, when man first settled into the Tibetan plateau, the recently domesticated Tibetan Mastiff interbred with the Tibet grey wolf, and a DNA swap being introduced at two genomic hotspots is the key to acquiring their special high altitude powers. And in a spectacular coincidence, it turns out to be the same location, same gene, same mechanism -- interbreeding -- as in humans with an ancient hominid known as the Denisovans.
