During the harsh conditions that prevailed in ice age China 146,000 years ago, a remarkable survival strategy was being developed by early humans—something that led to one of the region’s earliest technological revolutions.
In a series of recent discoveries at the Lingjing site in Northern China, archaeologists have unearthed evidence of sophisticated stone tools associated with Homo juluensis, an extinct human relative that inhabited parts of East Asia long ago, and which may even have interacted with ancestors of modern humans.
The findings, reported in the Journal of Human Evolution, have now revealed that stone crafting at the site began nearly 20,000 years earlier than previous estimates, placing these ancient toolmakers amid some of the harshest glacial period conditions, rather than the later warmer climate associated with past evaluations of the site.
The findings add to recent discoveries that have revealed surprising features about ancient archaic humans that thrived during this period, which include not only their unexpected size, but also their understanding of complex stone crafting techniques.
Creativity Driven by Cold
“People often imagine creativity as something that flourishes in good times,” said lead author Yuchao Zhao, the assistant curator of East Asian archaeology at Chicago’s Field Museum, in a statement. “Finding out that these stone tools were made during a harsh ice age tells a different story.
“Hard times can force us to adapt,” Zhao adds.
For more than a decade, archaeologists have undertaken excavations at Lingjing, where everything from animal remains to ancient tools has been uncovered.
Something else that the ancient human presence at this site has revealed is a surprisingly sophisticated ice age lithic industry, where the ancient humans who once thrived here employed a technologically complex manufacturing process for their time.
Evidence of this comes in the form of disc-shaped stone cores, which are deceptively simple in appearance. To craft them, their ancient makers had to carefully work them in ways that produced useful cutting flakes. Some of them were shaped evenly on both sides, while other examples reveal asymmetrical designs where one side served as a striking platform, and the other appears to have been prepared for controlled flake removal.
