The world’s oldest bed — and five other firsts

The most-cited discovery from Sibudu is the oldest known bedding: thin but consistent layers of compacted leaves from Cryptocarya woodii (an aromatic tree with documented insect-repellent properties), underlaid by Celtis africana (laurel) leaves forming a raised border, dated to approximately 77,000 years ago. The Sibudu people periodically burned these mattresses — ash layers at approximately 77,000–73,000 BP alternate with fresh plant layers — in what Lyn Wadley and colleagues interpret as deliberate sanitation against ticks, mites, and mosquitoes, since burned ash is alkaline and hostile to arthropod pests. This represents a form of public health awareness predating any other evidence of insect-avoidance behaviour by approximately 70,000 years. The second major discovery is compound adhesives: multi-component glues combining ochre, plant gum, and a fat or wax binder, applied to fix stone flakes to wooden handles (hafting), dated to approximately 70,000–75,000 years ago. Making these adhesives required sequential processing steps, knowledge of material chemistry, and deliberate planning. A third discovery is evidence for snares or traps: bones of blue duiker found with injury patterns consistent with snare capture rather than direct hunting, dated to approximately 70,000 years ago — the oldest known evidence of trapping technology. Fourth, heat-treated silcrete stone tools appear at approximately 72,000 years ago, predating the Pinnacle Point evidence and suggesting this technological innovation spread independently or was invented multiple times across the southern Cape. Fifth, the deposit contains evidence of a distinctive backed tool technology (Howiesons Poort industry) with geometric blade forms that appear and then disappear from the sequence, suggesting cognitive flexibility in technological tradition.
