A study in Nature journal shows that Denisovans co-existed with Neanderthals and interbred with our 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.

and this, which wow:

The study shows that Denisovans interbred with the ancestors of the present day people of the Melanesian region north and north-east of Australia. Melanesian DNA comprises between 4% and 6% Denisovan DNA.
