Ancient Tools in East Asia Reveal Middle Paleolithic Innovation
Archaeologist Hao Li and an international team report finding the first complete Quina tool kit in East Asia, at the Longtan site in southwest China. Quina scrapers are thick, asymmetrical stone tools with durable edges that were known from Europe and the Middle East, where they were used to cut meat, hides and wood and to extract marrow from bones. Luminescence dating of sand grains placed the Longtan layers at 50,000 to 60,000 years old, roughly the same time these tools were used by Neanderthals in Europe. Pollen analysis suggested an open forest-grassland and cool, dry climate similar to European sites. The team could not identify the toolmakers, who might have been modern humans, Neanderthals or Denisovans. Earlier scholars had assumed East Asia skipped the Middle Paleolithic, but the discovery and the Levallois finds at Guanyindong cave suggest otherwise. Researchers will look at deeper layers to learn whether the technology was invented locally or introduced.
It challenges the long-held view that East Asia stayed technologically static while Europe and Africa innovated, and it raises questions about who was making these tools.
The Denisovans are named after Denisova Cave in the Altai Mountains of Siberia, where their first fossil was found.
