Genetic analysis of the finger bone has since indicated that it was a remnant of a previously unknown hominin, distinct from both early modern humans and Neanderthals - the heavily muscled Homo species that cohabited with Homo sapiens in the region from 50,000 to 30,000 years ago. Early modern humans, the results suggested, shared parts of Eurasia not only with Neanderthals but a totally different human-like creature, and all three probably came into contact (the finger bone was found within 65 miles of known Neanderthal and modern human sites).

...genetic analysis has already shed new light on human ancestors' exodus from Africa and subsequent spread across the globe. The dominant theory holds that various hominin species left Africa in a series of distinct migrations, beginning with Homo erectus or a close relative a little under 2 million years ago, followed by the lineage that gave rise to Neanderthals, and finally the ancestors of modern humans about 50,000 years ago. The mitochondrial DNA of the Denisova hominin suggests its ancestors left Africa around 1 million years ago, at a time not previously associated with migration. (See "CSI Stone...
...colleagues are preoccupied with sequencing the Denisova hominin's nuclear genome. Using high-tech lab equipment and supercomputers, they are trying to make sense of this strange and startling discovery, in much the same way that their ancestors might have done tens of thousands of years ago, when they peered out into a windswept Siberian clearing and saw creatures at once familiar and foreign moving through the snow...
Lapp said that she and her team have been targeting organizations that will “enhance the community,” such as the Earthwatch Institute, which approached the University about a potential lease a little under a year ago...
...Students need to be integrated into the creation of the honor code in every step,” Bowman says. “[The UC] wrote a short paper advocating a number of years ago for an honor code, so it’s something that we have been behind for a while...
