Denisovan facts for kids
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.
DNA analysis has indicated that modern humans, Neanderthals, and the Denisova hominin last shared a common ancestor around 1 million years ago.
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.

Denisovans appear to have crossed the Wallace Line.
