Craftspeople in the Lake Chad basin carved the Dufuna canoe from a single log approximately 8,000-8,500 years ago, creating an 8.4-meter watercraft with pointed bow and stern. Discovered in 1987 in Yobe State, Nigeria, the canoe demonstrates advanced woodworking techniques developed before metal tools were available in the region. The design suggests understanding of hydrodynamics and indicates boat-building was already an established practice. Archaeological analysis shows this vessel represents Africa's oldest known boat and the world's second-oldest, created when the Lake Chad basin was significantly larger than today.
