A finger bone fragment of a juvenile female was discovered. She lived about 41,000 years ago, with about 3% to 5% of the DNA of Melanesians and Aboriginal Australians and around 6% in Papuans deriving from Denisovans.
The mitochondrial DNA (mtDNA) of the finger bone showed it was genetically distinct from Neanderthals and modern humans. The nuclear genome from this specimen suggested that Denisovans shared a common origin with Neanderthals.
The mtDNA analysis also suggested that this species was the result of a migration out of Africa that came between a migration by Homo erectus individuals and later ones by some ancestors of most modern humans.
So far, the fossils of four distinct Denisovans from Denisova Cave have been identified through their DNA: Denisova 2, Denisova 3, Denisova 4, and Denisova 8. Denisova 2 and Denisova 3 are young females,and Denisova 4 and Denisova 8 are adult males. 
So far, only a finger bone, a toe bone and two teeth are the only body parts that have been found. The finger bone is from a woman. It is broader than a human finger. This fact suggests that Denisovans were more robust than any modern humans.
Mitochondrial DNA analysisEdit
The mtDNA from the finger bone differs from that of modern humans by 385 nucleotides in the mtDNA strand out of approximately 16,500. This is more than the difference between modern humans and Neanderthals, which is around 202 bases.
