World's oldest poisoned arrowheads reveal ancient human ingenuity

Archaeologists have identified 60,000-year-old poisoned arrowheads at South Africa’s Umhlatuzana Rock Shelter. Traces of toxic "gifbol" plant residue on quartz points suggest Middle Stone Age hunters used advanced chemistry to fell large prey. This discovery pushes back the timeline of complex human hunting, proving our ancestors mastered lethal engineering far earlier than previously thought.
