The Unknown Third Species

👧 In 2008, the finger bone of a little girl who lived around 40,000 years ago was found in a cave in the Altai Mountains.

🦴 Palaeogeneticists were able to extract and sequence DNA from the knuckle.

👆 The girl belonged to a previously unknown species of humans.

🗺️ These people were baptised Denisova people after the place where they were found.
