This is such a cool finding--the oldest direct evidence of poisoned arrows. Poisoned hunting weapons were a game-changing innovation for our ancestors. Absolutely incredible that researchers found traces of plant toxins on these tiny arrowheads from 60,000 ago 🤯🏹 🧪
Humans Made Poisoned Arrowheads Thousands of Years Earlier Than Previously Thought
The use of poison on arrows marked a revolution in human hunting technology—new evidence suggests it happened tens of thousands of years earlier than previously known
