A study published in Nature on August 22 analyzed the piece of bone and discovered that the ancient girl that the fragment belonged to was a never-before-discovered hybrid of two ancient human relatives: a Neanderthal and a Denisovan.
Neanderthals and Denisovans inhabited Eurasia for thousands of years until around 40,000 years ago when they were replaced by modern humans. The Neanderthals primarily occupied the west and the Denisovans were found in the east.
