50,000-Year-Old Tools Found in China Could Point to Unknown Human Ancestor

Researchers found European-style Quina
tools in China, dating back 55,000 years,
challenging the view that East Asia’s Middle
Paleolithic era was stagnant and opening new
questions about early human innovation and
migration.
Archaeologists have identified a complete
Quina technological system, a distinctive
method of tool production, at the Longtan
site in southwest China. This site has been
dated to approximately 50,000 to 60,000
years ago. While Quina technology has been
well-documented in Europe for decades, this
is the first time it has been found in
East Asia.

The Quina system identified in China has
been dated to 55,000 years ago, which is in
the same period as European finds. This
disputes the idea that the Middle Paleolithic
was stagnant in the region and deepens the
understanding of Homo sapiens, Denisovans,
and possibly other hominins.

“That could answer the question of whether
these tools are the product of a modern human
like you and me,” Marwick said. “There have
never been any Neanderthals found in East
Asia, but could we find a Neanderthal? Or, more
likely, could we find a Denisovan, which is
another kind of human ancestor? If we can find
the human remains associated with this period,
we might find something surprising — maybe even
a new human ancestor that we don’t know about
yet.”
