Bones recently found in a Siberian cave have given researchers a new glimpse into the timeline of an extinct human species. The species – known as Denisovans – at one time lived alongside Neanderthals in the same cave, the evidence showed. The only fossil evidence of the Denisovans was uncovered in Denisova Cave in the Russian Altai Mountains back in 1980, and amount to three teeth and bone fragments. It was a popular cave with these extinct species – according to another recent study, it was also populated with Neanderthals at one point. Her father had been a Denisovan and her mother a Neanderthal, so evidence of interbreeding between the two groups exists.
