Half-million-year-old wooden structure found in Zambia pushes back timeline of human woodworking

Wooden artifacts discovered near Kalambo Falls in Zambia date back 476,000 years.
The interlocking wooden logs represent the oldest evidence of humans building structural wood constructions.
The finding challenges beliefs that early humans were solely nomadic hunter-gatherers.
The discovery suggests early humans had more advanced woodworking skills and ingenuity much earlier than previously thought.
While the exact hominin species is unclear, Homo heidelbergensis is a likely candidate for constructing the wooden site.
