Re: Different type of human species found in Serbia
Very interesting, Ruts!
Here's a bit more to add:
A 30,000-year-old finger bone found in a cave in southern Siberia came from a young girl that was neither an early modern human nor Neanderthal, but instead belonged to a previously unknown group of human relatives who may have lived throughout much of Asia during the late Pleistocene epoch, according to new research (Reich, D. et al. Nature 468, 1053-1060 2010.

"It was fortuitous that this discovery came quickly on the heels of the Neanderthal genome, because we already had the team assembled and ready to do another similar analysis," Green said. "This is an incredibly well-preserved sample, so it was a joy to work with data this nice. We don't know all the reasons why, but it is almost miraculous how well-preserved the DNA is."

The comparative analysis, which included genome sequences of individuals from New Guinea and Bougainville Island, indicates that genetic material derived from Denisovans makes up about 4 to 6 percent of the genomes of at least some Melanesian populations. The fact that Denisovans were discovered in southern Siberia but contributed genetic material to modern human populations in Southeast Asia suggests that their population may have been widespread in Asia during the late Pleistocene, said David Reich of Harvard Medical School, who led the population genetic analysis.

"This study fills in some of the details, but we would like to know much more about the Denisovans and their interactions with human populations," Green said. "And
you have to wonder if there were other populations that remain to be discovered. Is there a fourth player in this story?"Read more here:
