At a dusty archaeological site in Greece's Peloponnese, researchers have just rewritten the story of human ingenuity—by uncovering two wooden tools so ancient that they predate all other known wooden implements by at least 40,000 years. Discovered at Marathousa 1, these artifacts date back 430,000 years and reveal that our ancestors were shaping wood with surprising sophistication during the Middle Pleistocene, a transformative period in human evolution when more complex behaviors were first emerging.
The discovery matters because wood, unlike stone, rarely survives the millennia. For wooden artifacts to endure half a million years requires extraordinary conditions—and Marathousa 1 has provided exactly that. An international team led by scientists from the University of Reading, the University of Tübingen, and the Senckenberg Nature Research Society examined every wooden fragment recovered from the site, searching for telltale marks under microscopes. What they found was unmistakable: two carefully worked objects that bore the unmistakable signs of human hands.
The first was a section of alder wood displaying clear shaping marks and wear patterns consistent with use. Researchers believe it may have served as a digging tool in soft ground near the lakeshore or perhaps as an implement for stripping bark from trees. The second object, fashioned from willow or poplar, was much smaller but equally deliberate in its carving. These weren't accidental creations or rough approximations—they were tools made with intention and skill. The study, published in the journal PNAS, documents the precise microscopic evidence of this work.
The archaeological context deepens the story. The site also yielded stone tools and butchered animal remains, including elephant bones, suggesting that early humans used this location as a hunting and processing ground near an ancient lakeshore. Yet they were not alone in this dangerous landscape. Among the artifacts, researchers discovered a large alder fragment bearing deep grooves—but these marks came not from human hands but from the claws of a large carnivore, possibly a bear. This single piece of wood captures the fierce competition for resources that defined the Pleistocene: two apex species, both at Marathousa 1, fighting for survival and dominance.
"The Middle Pleistocene was a critical phase in human evolution, during which more complex behaviors developed," explains Professor Katerina Harvati, a paleoanthropologist who leads the long-term research program at the site. The discovery pushes back the earliest reliable evidence of humans deliberately working with wood, expanding our understanding of what our ancestors were capable of nearly half a million years ago. Previous finds from sites in the United Kingdom, Zambia, Germany, and China showed wooden tools or handles, but all are significantly more recent. The only older piece of wood associated with humans comes from Kalambo Falls in Zambia, dating to around 476,000 years ago—but it was used as structural material, not as a tool.
What makes Marathousa 1 exceptional is not just the age of these artifacts but their context. Paired with stone implements, animal remains, and evidence of human behavior, they tell a fuller story of how our ancestors lived, hunted, and adapted to their world. The research was supported by the European Research Council and the German Science Foundation, drawing contributions from institutions across Europe and the United States. As excavations continue at this preservationally rich site, more secrets from the deep past may yet emerge.
