From the Ted Talk by Svante Pääbo: DNA clues to our inner neanderthal

Unscramble the Blue Letters

So this individual comes from a population that shares an origin with Neanderthals, but far back and then have a long innedpnedet history. We call this group of huanms, that we then described for the first time from this tiny, tiny little pciee of bone, the Denisovans, after this place where they were first described. So we can then ask for desinnavos the same things as for the Neanderthals: Did they mix with ancestors of present day people? If we ask that question, and compare the Denisovan genome to people around the world, we surprisingly find no evidence of Denisovan DNA in any people lviing even close to Siberia today. But we do find it in pupaa New geniua and in other islands in Melanesia and the Pacific. So this presumably means that these Denisovans had been more wespidread in the past, since we don't think that the ancestors of Melanesians were ever in Siberia.

Original Text

So this individual comes from a population that shares an origin with Neanderthals, but far back and then have a long independent history. We call this group of humans, that we then described for the first time from this tiny, tiny little piece of bone, the Denisovans, after this place where they were first described. So we can then ask for Denisovans the same things as for the Neanderthals: Did they mix with ancestors of present day people? If we ask that question, and compare the Denisovan genome to people around the world, we surprisingly find no evidence of Denisovan DNA in any people living even close to Siberia today. But we do find it in Papua New Guinea and in other islands in Melanesia and the Pacific. So this presumably means that these Denisovans had been more widespread in the past, since we don't think that the ancestors of Melanesians were ever in Siberia.
