Discovered Tools in China Reveal Enigmatic Neanderthal-like Artifacts
Uncovering Neandertal-Linked Artifacts in China's Hinterland:
Mysterious stone tools, reminiscent of those traditionally linked to Neandertals, have popped up in a remote corner thousands of miles away from their known territory in southern China. The river valley site of Longtan has revealed distinctive stone cutting and scraping implements, along with the rocks from which these tools were crafted, according to a team led by archaeologists Qi-Jun Ruan and Hao Li of the Institute of Tibetan Plateau Research in Beijing.
These finds, dating back approximately 50-60,000 years, challenge a widely-held notion that ancient toolmaking in East Asia was limited to basic, rudimentary tools. This groundbreaking discovery represents the first definitive examples of Quina scrapers and cores east of their initial discovery in France, as reported in the Proceedings of the National Academy of Sciences on March 31.
A remarkable find in the 2019 and 2020 excavations at Longtan yielded a total of 3,487 artifacts. From this collection, the researchers identified 53 Quina scrapers, characterized by their elongated, robust design, and the numerous times they had been resharpened. Another 14 artifacts were classified as cores, having been meticulously chiseled to form the base for Quina scraper production.
Whether these tool-making techniques were introduced by Neandertals or indigenous populations remains a puzzle. The possibility exists that Denisovans, who inhabited southern Siberia more than 200,000 years ago, could have independently developed the Quina tools within East Asia. However, there's no concrete evidence to support the idea of Denisovan migration outside of East Asia, leaving the potential for European Neandertals to have shared their knowledge of Quina toolmaking with the Longtan region's inhabitants.
Mobile groups such as those at Longtan likely benefited from the versatility and reusability of the Quina tools, according to archaeologist Davide Delpiano of the University of Ferrara. As the region faced increasingly challenging climatic conditions, it is plausible that Denisovans or other Asian hominid populations may have innovated Quina tools independently.
Intriguing developments may follow as the team uncovers more than 30 sites surrounding Longtan, containing Quina artifacts in the same river valley. This exciting discovery sets the stage for future research into the complex cultural exchanges and technological advancements among ancient human populations.
- This discovery in the Longtan river valley challenges a widely-held policy that ancient toolmaking in East Asia was restricted to basic, rudimentary tools.
- These finds, dating back about 50-60,000 years, come from a region thousands of miles away from the known Neandertal territory in southern China.
