An archaeological discovery in Zambia is significantly altering the understanding of human evolution. Researchers from the universities of Liverpool and Aberystwyth uncovered a wooden structure estimated to have been built nearly half a million years ago, 300,000 years prior to the appearance of Homo sapiens. This finding indicates that early human ancestors may have possessed cognitive capabilities far more advanced than previously believed.

The structure, found along the Kalambo River near a waterfall on the border between Zambia and Tanzania, consists of two large, deliberately interlocked wooden trunks, forming a stable configuration. This level of complexity in wooden construction had not been seen in earlier records of human activity, which predominantly included stone tools, skeletal remains, or evidence of fire.

The implications of this discovery are profound, as it challenges the existing timeline of human development and suggests that the cognitive abilities of early human ancestors were more sophisticated than previously understood. It opens up new avenues for research into the social structures and environmental adaptations of these ancient beings, potentially reshaping our narrative of human history.
