Krause and Pääbo's analysis, published online on Wednesday by the journal Nature, is the first to identify a novel hominin based on genetic analysis alone - without fossilized remains to offer anatomical reference. But the researchers stop short of declaring the human-like creature a brand-new...
Wednesday's results come from an analysis of the creature's so-called mitochondrial DNA, which is inherited only from the mother, and therefore does not give as complete a picture as nuclear genome sequencing. "In terms of mitochondrial DNA alone, this hominin was twice as distant from us as...
Scientists have no idea what the Denisova hominin looked like or how it behaved and interacted with early modern humans, and perhaps never will without a more complete fossil record. But even the preliminary genetic analysis has already shed new light on human ancestors' exodus from Africa and subsequent spread...
Pääbo says that because the Denisova hominin is assumed to be human, it's possible that there are many other unknown hominin fossils waiting to be discovered. He says paleontologists will continue to scour for remnants in Siberia and other northern regions, where cold weather helps preserve...
Ian Tattersall of the Department of Physical Anthropology at the American Museum of Natural History, who was not involved in the research, calls the Denisova hominin a "significant addition" to the emerging picture of our past - one we now know we shared with a number of other hominin species. "We...
