denisovans

Presumably they mean ones that ended up being Denisovans and Florensis.

The exception to this would be if you were to classify Neanderthals or Denisovans as non-human.

More accurately humans acquired the high-altitude tolerance gene variant from Denisovans and it was selected for in the ancestors of modern Tibetans.

I'd argue that the discovery of Denisovans might be bigger than Neanderthal genes, but they're in the same ballpark.

Actually the Denisovans gene transfer most likely occurred somewhere in South East Asia.

Sapiens prior to the disappearance of the Denisovans about 40,000 years ago.

There is one morphological clue from the Denisovans that could be used to match the Chinese skulls - the huge size of the tooth.

All of them, Erectus, Heidelbergensis, Neanderthals, Denisovans and Sapiens were walking around at the same time.

Yeah but chimps and denisovans lived fine without as many copies.

Heidelbergensis is the last common anscestor of Neanderthals, Denisovans and us.

The Denisovans were a different species to Homo sapiens.

Neanderthals and Denisovans are very, very close to H.

I believe "sub-species" is preferred on the level that you're indicating—think neanderthals and denisovans.

Given what we now know about backmigration and intermixing (particularly with Denisovans), it's really not coherent to say any "out of" theory is the Truth.

According to the article: "...but the evidence also suggests that Denisovans and humans interbred." can we estimate the odds of that being mutally independnt mutation Yeah, that's kind of what they are doing.

What did they measure - which part of the genome did they say is human and which Denisovans.

As if that weren't enough, the same can also be said of Denisovans.

Summary: Tibetans apparently get their high-altitude tolerance from Denisovans, through interbreeding with H.
