Move over Neanderthals. Humans have another long extinct ancestor to credit for our evolution. They're called Denisovans.

Scientists found a finger bone fragment of one of them in a Russian cave in 2008. New technology allowed researchers to map the DNA.

They found these extinct people lived in the Philippines, Australia and Polynesia. Natives of those countries still derive 5 percent of their DNA from Denisovans.

Scientists say Denisovans had dark skin, brown hair and brown eyes.
