Re: Extinct Humans Passed High-Altitude Gene to Tibetans
#2Readers who are interested in this kind of thing may be interested in the new book by Svante Pääbo, Neanderthal Man: In Search of Lost Genomes.[1] Pääbo was the first researcher to figure out how to sequence DNA from ancient human beings, starting with Egyptian mummies and eventually leading to the complete sequencing of Neanderthal nuclear genomes.

#3I wondered this about Neanderthals, now Denisovans: in what sense are they extinct if their progeny still walk the Earth?

The same sense dinosaurs are extinct while their progeny still walk/fly on earth.

#5Perhaps 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?

That is a different sense. Totally different timescales, and dinosaurs were many species.

Easy. Tibetans are humans, with a small contribution of special adaptations from another species.
A human that has one Neanderthal gene is not a Neanderthal. Therefore, Neanderthals are still extinct.

How many Neanderthal genes make a Neanderthal?

More than half at least, as a mule is neither donkey nor horse

That's also a good book on the politics of such research.
"The Neanderthals Rediscovered", by Papagianni and Morse, has a good chronology of the species based on what is known to date.
