Direct evidence for poison use on microlithic arrowheads in Southern Africa at 60,000 years ago.
Poisoned weapons are a hallmark of advanced hunter-gatherer technology. Through targeted microchemical and biomolecular analyses, we identified traces of toxic plant alkaloids on backed microliths from Umhlatuzana Rock Shelter in KwaZulu-Natal, South Africa, excavated from a level dated to 60,000 years ago.
