300,000-year-old wooden tools found in China

An international research team has unearthed 35 wooden tools dating back 300,000 years at an archaeological site in southwest China, offering new insights into early human technology and diet in East Asia. The discovery, published Friday in the journal Science, marks the earliest known evidence of complex wooden tool technology in the region and reveals that ancient humans relied heavily on plant-based diets rather than hunting.

The tools were found preserved in oxygen-deprived clay sediments at the Gantangqing site in Yunnan province, challenging long-held assumptions about technological development in prehistoric East Asia.

Discovery Details

The wooden artifacts, crafted primarily from pine and hardwoods, include digging sticks and unique hook-shaped implements designed for harvesting underground plants. Researchers from the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences led the excavation, which also yielded stone tools, animal fossils, and plant remains.uow+3

"This discovery is exceptional because it preserves a moment in time when early humans were using sophisticated wooden tools to harvest underground food resources," said Professor Bo Li from the University of Wollongong, a co-author of the study. The tools show evidence of deliberate craftsmanship, with cutting marks, polished surfaces, and soil residues containing plant starch grains.china+2

Using advanced dating techniques, including single-grain infrared luminescence, researchers determined human activity at the site occurred between 361,000 and 250,000 years ago.miragenews+1

Plant-Based Survival Strategy

The tools reveal that East Asian early humans developed a distinct survival strategy focused on foraging roots, tubers, and other underground plants. Evidence at the site includes remnants of pine nuts, hazelnuts, kiwi fruit, and aquatic tubers.independent+1

This contrasts sharply with contemporaneous European sites like Schöningen in Germany, where wooden tools were primarily hunting implements designed for taking large mammals. "The discovery challenges previous assumptions about early human adaptation," Li explained.miragenews+2

Historical Context

The Gantangqing discovery represents a significant breakthrough in understanding early human technology in East Asia, providing empirical support for the long-debated "bamboo and wooden tools hypothesis". This hypothesis suggests ancient East Asian populations relied heavily on implements made from perishable materials like wood and bamboo, using stone tools primarily for processing tasks. The site was first unearthed in 1984, with major excavations conducted in 1989, 2014-2015, and 2018-2019.phys

Wooden artifacts from this time period (Early Paleolithic) are extraordinarily rare worldwide, as wood typically decomposes rapidly due to microbial activity, oxidation, and weathering. Outside Africa and western Eurasia, wooden tools older than 50,000 years are virtually absent from the archaeological record. The Gantangqing tools survived due to exceptional preservation conditions in the low-oxygen, clay-heavy sediments of an ancient lakeshore, offering a unique window into prehistoric woodworking technologies that would otherwise have been lost to time.chinadaily+1
