A recent DNA study was made to a 40,000 year old-finger bone of a young girl which was found in Siberia in 2008 seems to reveal a new type of ancient type of human, according to National Geographic on Wednesday.

Apparently, the DNA study showed that the finger bone was to be neither from the early humans nor from the previously discovered Neanderthal, but rather suggest to be belonging to the previously unknown species, which is now called Denisovan.

The finger bone including a tooth fragment, as shown in the photo, was believed to be from a 5 to 7 year old girl were found inside the Denisova cave in southern Siberia, and experts believed that Denisovan may be related to the Neanderthal.

Bence Viola, one of the co-authors of the DNA study said that the Denisovans may have not been to Papua New Guinea, which is located at the northwestern edge of the Pacific region called Melanesia.

“We think the Denisovan population inhabited most of eastern Eurasia in the same way that Neanderthals inhabited most of western Eurasia,” Mr. Viola said, who is also an anthropologist from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

“Our idea is that the ancestors of Melanesians met the Denisovans in Southeast Asia and interbred, and the ancestors of Melanesians then moved on to Papua New Guinea.” The anthropologist added.
