Denisova's first hominids occupied a Siberian cave 200,000 years ago
Excavations in Denisova Cave, in the Altai Massif, began 40 years ago. In the layers of material from the Middle Paleolithic (around 340,000 to 45,000 years ago) and the Early Upper Paleolithic, many of the keys to the life of some of the hominids that are in the branch of the evolutionary tree of our species have been found, Homo sapiens.
