Archaeologists working in Zambia have uncovered the world’s oldest wooden structure dating back to 476,000 years ago.
The discovery, according to the leader of the team, Larry Barham, an archaeologist at the University of Liverpool, suggests that “human ancestors had built structures made of wood and may have been more complex than previously thought.”
The wooden structure, a pair of interlocking logs connected by a notch, was discovered along the Kalambo River in Zambia, with the details published in the journal, Nature, last week.
“The exceptionally well-preserved wooden structure was found at Kalambo Falls in the north of Zambia near the border with Tanzania. It dates back at least 476,000 years, well before the evolution of Homo sapiens,” the publication reads.
“The wood bears cut-marks showing that stone tools were used to join two large logs to make the structure, which is believed to be a platform, walkway or raised dwelling to keep our relatives above the water.
“A collection of wooden tools, including a wedge and a digging stick, were also discovered at the site. It dates back at least 476,000 years before the evolution of Homo Sapiens.
“The ancestors of humans were already known to use wood at this time, but for limited purposes such as starting a fire or hunting”, it adds.
Barham said that to his knowledge, the previous record-holder for oldest wooden structure dated back around 9,000 years.
He added that the structure was a “chance discovery” made in 2019 while excavating at the site located on the banks of the Kalambo River, above 770-foot waterfall.
“Discoveries involving such ancient wood are rare, because it tends to rot leaving behind little trace for the historical record. But the high level of water at Kalambo Falls is believed to have preserved the structure over the centuries,” he said.
