Explanation: 

Detailed explanation-1: -The remains of a little finger discovered in a cave in the mountains of southern Siberia belong to a previously unknown human ancestor, scientists said today. The finding suggests an undocumented human species lived alongside Neanderthals and early modern humans in parts of Asia as recently as 30, 000 years ago.

Detailed explanation-2: -Among the eight human fossils unearthed there are the pinkie, three bones from Neanderthals, and even one from a child with one Neanderthal and one Denisovan parent. The cave also contains sophisticated stone tools and jewelry at higher, later levels. But no modern human fossils have been found there.

Detailed explanation-3: -Bone fragments of the Denisova hominin originate from the cave, including artifacts dated to around 40, 000 BP. A 32, 000-year-old prehistoric species of horse has also been found in the cave. The cave is located in a region thought to have been inhabited concurrently in the past by Neanderthals and by modern humans.
