Archaeologists have found that early humans in what is now China were using sophisticated stone tools as far back as 160,000 years ago.
"This discovery challenges the perception that stone tool technology in Asia lagged behind Europe and Africa during this period," the research team wrote in a statement about the discovery.

"The identification of the hafted tools provides the earliest evidence for composite tools in Eastern Asia, to our knowledge," the team wrote in a study published Tuesday (Jan. 27) in the journal Nature Communications.
Researchers already knew of extremely early tool use in East Asia, with the oldest known wooden tools there dating to 300,000 years ago. However, the new findings, which were excavated between 2019 and 2021, are the earliest known tools consisting of two materials, as is evidenced by the hafted artifacts.
Hafting "is a new technological innovation whereby the stone tool is inserted or bound to a handle or a shaft," Michael Petraglia, director of the Australian Research Centre for Human Evolution at Griffith University and a co-author of the paper, told Live Science in an email. "This improved tool performance by allowing the user to increase leverage and providing more force for actions such as boring."
It appears that the tools were used to process plant materials. "Microscopic analysis on the edges of the stone tools indicate boring actions, used against plant material, likely wood or reeds," Petraglia said.

Ben Marwick, an archaeology professor at the University of Washington and a co-author of the paper, said it is not clear which early human species made the tools.
"The exact identity of the makers of these tools is not clear, because during this time there were probably multiple hominin species living in the region," Marwick told Live Science in an email. "So it could be, for example, the Denisovans, H. longi, H. juluensis or H. sapiens that made these tools. Hopefully future work will recover fossil remains or DNA that will shed more light onto this interesting question."

It is noteworthy that many of the artifacts are small — less than 2 inches (50 millimeters) — but were made with complex techniques, Marwick noted. "These come from a period when previous archaeological research has mostly found large artefacts produced using simple flaking methods," he said. "So our finds suggest that complex tool production strategies appear earlier than previously understood."
The newly discovered tools date to between 160,000 and 72,000 years ago. At this time, people in the region lived as hunter-gatherers, but the details of their lifestyles are unclear.
"While the lack of mammal bones and other evidence makes it difficult to deduce how they lived, at least, their stone tools indicate a high degree of behavioral flexibility and successful adaptation to the local climate and resources," Shi-Xia Yang, a paleoanthropologist at the Chinese Academy of Sciences who is a co-author of the paper, told Live Science in an email.
Stone tools in East Asia
The discovery of the sophisticated stone tools from this region and time period dispute a long-held assumption about early toolmaking, the study authors noted.
"The broader relevance of the finds are that they challenge the entrenched bias that East Asian hominins only produced 'conservative' tools," Marwick said. "The bias was deeply entrenched, dominating archaeology for over half a century through the concept of the Movius Line.
"Proposed in the 1940s, this 'line' suggested a geographical divide between the 'advanced' Acheulean handaxe cultures of Africa and Western Eurasia and the 'conservative' chopper-chopping tool cultures of East Asia," he continued. "This created a narrative of East Asia as a cultural backwater, where hominins were thought to be evolutionarily stagnant."
John Shea, an anthropology professor at Stony Brook University who was not involved with the research, praised the paper but noted that the idea that East Asia was a cultural backwater was never accurate. He noted that, in his own stone tool experiments, the small, complex and sharp stone tools that were being constructed more often in Europe could be dangerous to work with. "Trust me on this, for I have the scars to back it up," he said.
Any "hominins with a lick of common sense almost certainly minimized the amount of time they spent pounding out razor-sharp flakes," Shea said. "In this respect, [Southeast] Asian hominins were doing what one would expect them to do. … The "idea that 'simple tools equals simple minds' is archaeological mythology."

Anne Ford, an associate professor of archaeology at the University of Otago in New Zealand, praised the research.
"This is really an excellent discovery and highlights our need to move away from older descriptions of Asian technologies as simple core-flake industries," Ford told Live Science in an email. She noted that hafting is an "important technological step and has implications for assessing the cognitive ability of hominins in China during this time period."
