Scientists have discovered that stone tools found in central China are about 20,000 years older than previously thought. The tools, discovered at a site called Lingjing in Henan province, are roughly 146,000 years old. Researchers dated them by measuring tiny crystals inside a fossilised deer bone that was buried with the tools.
What makes this discovery important is not just the age, but what the tools reveal about the toolmakers. These were not simple rocks, but carefully crafted stone cores shaped using a sophisticated technique called centripetal flaking. This method required planning, precision, and deep knowledge of how stone breaks. For many years, scientists believed that early humans in East Asia were less advanced than those in Africa and Europe. However, the Lingjing tools suggest otherwise.
The tools were made by Homo juluensis, an extinct human species with a large brain and a unique combination of features. The site itself appears to have been a butchery location where ancient hunters processed animals like deer. The discovery suggests that people can develop creative solutions and advanced skills even in harsh, cold conditions. Lead researcher Yuchao Zhao from the Field Museum in Chicago explained that hard times can push people to adapt and innovate. The Lingjing site shows that prehistoric people in East Asia were doing sophisticated work that scientists previously associated only with Neanderthals and African cultures.
