Plant-poisoned arrowheads show early hunting innovation 60,000 years ago
Research in Science Advances shows South African hunter-gatherers used plant-based poisons on stone arrowheads about 60,000 years ago, pushing back poisoned-weapon timelines significantly and globally.

Overview
Who: South African hunter-gatherers applied plant-derived toxins to stone arrowheads, according to new chemical analyses reported in the Science Advances study.
What: Evidence indicates the use of plant poisons on hunting weapons around 60,000 years ago, predating previously known poisoned weapons by tens of thousands of years.
Where and when: Finds from South Africa are contrasted with later evidence, such as 6,700-year-old poisoned weapons at Kruger Cave and bone arrowheads in an Egyptian tomb.
How: Researchers used residue and chemical analyses to identify plant-derived compounds on stone tools, demonstrating deliberate application of poisons rather than incidental contamination.
Why it matters: The discovery revises timelines for complex hunting technology and cognitive behavior, implying early hunter-gatherers developed advanced weapon enhancements far earlier than assumed.
