The ancient humans have been dubbed “Denisovans” after the caves in Siberia where their remains were found. There is also evidence that this population was widespread in Eurasia. A study in Nature journal shows that Denisovans co-existed with Neanderthals and interbred with other ancestors of the human species – perhaps around 50,000 years ago. An international group of researchers sequenced a complete genome from one of the ancient hominins (human-like creatures), based on nuclear DNA extracted from a finger bone. Professor Chris Stringer: “It’s nothing short of sensational – we didn’t know know how ancient people in China related to these other humans”. Scientists say an entirely separate type of human identified from bones in Siberia co-existed and interbred with Neanderthal, Cro Magnon, and others.
Scientists were able to analyse DNA from a tooth and from a finger bone excavated in the Denisova cave in southern Siberia. The individuals belong to a genetically distinct group of humans that were distantly related to Neanderthals but even more distantly related to the ancestors of Cro Magnon, universally considered the first fully "modern" human.
