A groundbreaking archaeological discovery in southwestern China has unearthed the oldest known wooden tools from East Asia, dating back approximately 300,000 years. This find provides the first substantial evidence that early humans in the region extensively used wood for technology, potentially marking a distinct “Wood Age” in East Asian prehistory. The collection of 35 sophisticated tools, discovered among nearly 1,000 wooden artefacts at the gantangqing site in Yunnan province, challenges long-held assumptions about the technological capabilities and survival strategies of ancient human populations outside of Africa and Western Eurasia. Published in the prestigious journal Science, this research fills a critical gap in our understanding of human innovation during the Palaeolithic period.
Unearthing the Past: A Landmark Discovery in Yunnan
The remarkable artifacts were found during excavations conducted in 2015 and 2018 at the Gantangqing site. Situated near the southern edge of Fuxian Lake, Yunnan’s largest lake, this location proved vital for preservation. The site was recognized as one of China’s top 10 archaeological discoveries in 2015 after the initial findings.
Researchers uncovered a total of almost 1,000 wooden items. Among these, 35 showed clear signs of deliberate shaping and use. These represented the very first wooden tools recovered from a Palaeolithic site in East Asia. The Palaeolithic period, often referred to as the early Stone Age, spans a vast timeline from roughly 2.5 million to 10,000 years ago.
Professor Gao Xing, a corresponding author from the Chinese Academy of Sciences, hailed the discovery as “world-class.” He emphasized the significance of the wooden tools for understanding early human behavior in the region. Lead author Liu Jianhui, from the Yunnan Institute of Cultural Relics and Archaeology, had previously highlighted in 2015 that finds like Gantangqing “fill a gap” in the study of ancient Chinese wooden tools. Liu also spearheaded the second excavation phase in 2018, which yielded further insights.
Challenging the Conventional Narrative: Beyond Stone and Bronze
Our traditional understanding of human technological development often describes stages defined by materials like stone, bronze, iron, and eventually steel. However, assessing the role of wood has been difficult. Wood decomposes easily, leaving little trace in the archaeological record compared to durable stone or metal. Evidence of ancient wooden tools from the Early and Middle Pleistocene (2.58 million to 130,000 years ago) has been exceptionally scarce worldwide. Previously, notable collections were primarily found in Africa and Western Eurasia. The most extensive one came from Schöningen in Germany.
The Gantangqing discovery dramatically alters this picture. It provides compelling evidence that sophisticated wooden technology was widespread in East Asia hundreds of thousands of years ago. This suggests that alongside stone tools, wood played a crucial, perhaps even dominant, role in the daily lives and survival strategies of early East Asian populations. The term “Wood Age” is now being discussed in the context of this region, much like it has been speculated for others where organic tools were likely prevalent.
Compared to sites like Schöningen, which primarily yielded hunting implements like spears, Gantangqing presents a more diverse array of wooden tools. Crucially, its collection is heavily focused on implements designed for interacting with plants, suggesting a different subsistence strategy was at play.
Tools of Survival: Specialized Craftsmanship for Plant Foraging
The 35 identified tools from Gantangqing reveal a level of craftsmanship and specialization previously underestimated for East Asian hominins of this period. The collection includes a variety of shapes and sizes, indicating diverse functions. Most notably, the majority appear to have been used for digging.
Researchers identified large, potentially two-handed digging sticks, alongside smaller, pointed hand tools. Uniquely shaped “hook-like” tools, possibly crafted from trunk bases or roots, were also found, speculated to be used for cutting or grubbing roots. Analysis even revealed small, lozenge-shaped pieces, potentially awls or tools for separating tangled roots. Four soft hammers, made of wood or wood combined with deer antler fragments, represent the earliest known wooden hammers in East Asia.
Most of these tools were fashioned from pine wood. A smaller number utilized harder wood species. Detailed analysis revealed clear evidence of intentional shaping techniques, including whittling and carving marks. Surfaces showed smoothing where branches had been removed. Crucially, scientists found use-wear evidence, such as soil residues, tip damage, polish, and striations, consistent with repeated contact with plant materials. This analysis, including identification of starch grains from tuber plants, strongly indicates the tools were used for extracting plant resources, likely aquatic plant rhizomes, from the edges of the ancient lake.
The Plant-Focused Strategy: Adapting to a Subtropical Environment
The evidence from Gantangqing points towards a sophisticated plant-based survival strategy among early humans there. The site’s location near ancient Lake Fuxian provided a rich environment. Environmental data suggests a diverse range of edible resources were available, including pine nuts, hazelnuts, berries, kiwi fruit, and various aquatic plants with edible stems, seeds, and underground storage organs like tubers and rhizomes.
The specialized nature of the wooden tools, particularly the digging implements, implies that these early humans made planned visits to the lakeshore. They were strategically exploiting these underground resources. This contrasts sharply with contemporary European sites like Schöningen, where the archaeological record strongly suggests a focus on hunting large game. The subtropical climate around Lake Fuxian likely offered year-round plant availability, providing a stable food source that could sustain populations without heavy reliance on hunting megafauna. This highlights the adaptability of early human populations, developing diverse, region-specific subsistence strategies.
Preservation Puzzle: How 300,000-Year-Old Wood Survived
The extraordinary preservation of organic materials like wood at Gantangqing is key to this discovery’s importance. Wooden artefacts from this deep in time are incredibly rare because wood typically decays rapidly.
The site’s location near ancient Fuxian Lake provided the unique conditions necessary for preservation. The tools and other organic remains were found embedded in lake sediment deposits. Fluctuations in the ancient lake’s water level likely caused rapid burial of artifacts dropped or left near the shore. This rapid covering by fine clay particles created an oxygen-poor environment. This lack of oxygen is crucial. It prevented oxidation and shielded the organic remains from decomposition, allowing them to survive for 300,000 years. This unique taphonomy makes Gantangqing an unparalleled window into a technological world that is usually invisible to archaeologists.
Rewriting East Asian Prehistory: The Bamboo Hypothesis and Beyond
For decades, archaeological evidence from East Asia, primarily based on stone tools, sometimes appeared simpler compared to assemblages found in Africa or Western Eurasia. This led to questions about the technological sophistication of early East Asian populations. The Gantangqing wooden tools fundamentally challenge this view.
The complex craftsmanship and specialized functions of these wooden implements demonstrate advanced planning, environmental knowledge, and considerable technological skill. The apparent simplicity in stone tools at sites like Gantangqing might reflect functional choices based on locally abundant organic materials, not a lack of capability. The presence of diverse organic resources, including potentially bamboo, in East Asia has long led to the “Bamboo Hypothesis,” suggesting early humans here relied heavily on perishable materials that don’t survive well. The Gantangqing wooden tools provide the first direct, robust evidence supporting this hypothesis. They prove sophisticated organic tool technology existed.
Furthermore, the site also yielded stone tools (though described as relatively simple) and the early antler soft hammers. This suggests the Gantangqing inhabitants possessed a complete, multi-material toolkit. This toolkit was adapted to their local environment and available resources, utilizing stone, wood, and bone/antler effectively. The discovery underscores that relying solely on surviving stone tools can provide an incomplete or even misleading picture of early human technological prowess.
Advanced Dating Methods Confirm Ancient Origins
Pinpointing the precise age of such ancient artifacts requires advanced scientific techniques. Researchers employed sophisticated dating methods to establish the timeline for the Gantangqing tools. These included infrared luminescence dating on potassium feldspar grains and electron spin resonance dating on a mammal tooth found within the same archaeological layers.
These analyses confirmed the ancient origins of the wooden tools. The dating established their age to fall within a range of approximately 361,000 to 250,000 years ago. This firmly places them within the Middle Pleistocene period, specifically dating layers from around 300,000 years ago within the broader Gantangqing site chronology. This rigorous dating provides solid chronological context for the unprecedented findings.
Collaborative Research Drives Landmark Findings
The landmark study published in Science was the result of extensive collaboration. Researchers from the Yunnan Institute of Cultural Relics and Archaeology and the Institute of Vertebrate Palaeontology and Palaeoanthropology under the Chinese Academy of Sciences led the project. They partnered with international institutions, including the University of Wollongong in Australia, the University of Exeter, and the University of Hong Kong, among others. This interdisciplinary and international effort was crucial in bringing together the expertise needed for excavation, artifact analysis, dating, and environmental reconstruction.
