A 30,000-year-old fossil finger bone found in a Siberian cave belonged to a previously unknown strain of human, scientists said yesterday.
The surprise discovery came after researchers analysed the unusually well-preserved bone’s DNA. It came from a young girl who was neither “modern human” nor Neanderthal.
The findings, reported in the journal Nature, said she belonged to a separate, now extinct, branch of the human family tree
A molar tooth from the cave is also believed to be from a Denisovan.
The finds alter the story of evolution. They suggest Neanderthals had an Asian sister group that broke away on their own evolutionary path before dying out.
It is thought ancestors of the Neanderthals left Africa 350,000 years ago to settle in Europe and Eurasia.
