Paleoanthropology is the scientific study of human evolution. A subfield of antropology, paleoanthropology is the study of the evolution of human biology, culture, and society .

* Denisovans began as Homo erectus that migrated out of Africa to the Altai Mountains in the Denisova Cave of Siberia. Occupation in this Russian cave, based on artifacts found, began during the Middle Pleistocene. It is assumed that Denisovans lived concurrently with Neanderthals at some point in time since there is DNA evidence of a young girl “Denny” who had a Denisovan father and Neanderthal mother. Possible names given to the Denisovan fossils are still being debated:
Homo denisova, Homo altaiensis, and Homo sapiens denisova.
