World’s oldest wooden structure discovered in Zambia

Published on 27 Sep 2023

Archaeologists have discovered what is thought to be the world’s oldest known wooden structure near the border of Zambia and Tanzania.
Found along a riverbank in Zambia, the simple structure consists of two interlocking logs of a large-fruited willow tree. One log lies on top of the other and is held in place by a notch in its underside.
Marks on the wooden structure show that the logs were carved, chopped, and shaped with sharp stone tools. The structure predates modern humans and probably served as a walkway for human ancestors who lived along the Kalambo River nearly half a million years ago.
