How the discovery of an ancient stone tool could rewrite human history

• Neanderthal-like stone tools, made using the Quina method, have been discovered in China, challenging the conventional understanding of human evolution in East Asia.
• This discovery disputes the idea that the Middle Stone Age (between 300,000-30,000 years ago) was a period of stagnation in East Asia, while Europe and Africa saw significant advancements.
• A Quina stone scraper, thick and asymmetrical with a broad and sharp working edge, was found with clear signs of use and resharpening.
• Researchers are uncertain whether this technology was introduced to East Asia by westward migration or developed independently.
• Further investigation, including the search for ancient human remains, may reveal whether this technology is linked to Neanderthals, Denisovans, or even an unknown human ancestor.
