Perhaps not entirely surprising, when you consider how much better Tibetan high-altitude adapations are when compared to Andean people's. So the idea that they evolved in the span of 3,000 years seems suspect. Very interesting that they seem to have picked them up from a relict population - perhaps this is related to the Yeti stories?
