BEIJING, March 27-- Scientists used a DNA-decoded method to investigate an ancient human who has been discovered in a cave in southern Siberia, according to British newspaper Daily Mail.

The mysterious human, who lived alongside our ancestors tens of thousands of years ago, earned a nickname “X-Woman”.
Through analysing DNA from a fossilized finger bone, researchers found it doesn't match modern humans or Neanderthals, two species that lived in that area around the same time - 30,000 to 50,000 years ago.
The Siberian species lineage may split off from the branch leading to moderns and Neanderthals a million years ago, the researchers calculated.
And they also said that it doesn't seem to match the history of human ancestors previously known from fossils.
Researchers presumed that the Siberian species may be brand new, although they cautioned that they're not ready to make that claim yet.
This paleoanthropological breakthrough may rewrite mankind's family tree.
