Abstract
In the very heart of Central Asia and far from any African influence, the Denisova cave has played the role of either a sediment gap or for numerous human successive occupations, from 280 to 20 thousands years. We can follow an autonomous regional evolution that takes part in continental cultural systems. At the lower levels, thick and short flakes are dated between 280 and 250 thousands years. A long historical follows from 180 to 40 thousands years with high quality blade Levallois technology. These assemblages belong to regional technical exchanges networks, and to exportations of cultural traits, linked to intense activities on the spot. At the end, between 40 and 20 thousands years, we found innovations both in technologies and in symbols (bone tools and pendants), apparently without external influences. We have not observed any relation between technological styles and the human biological variations (“modern”, Neanderthal or Denisoviens).
