How Did Ancient Humans Know What Was Safe to Eat?

The famous survival rule that claims to keep you safe from deadly wild plants might actually get you killed. We are told that testing unknown berries against our skin, lips, and tongue is how our ancestors survived in the wild. But the Universal Edibility Test is a modern invention—and for some of the deadliest toxins on Earth, it fails catastrophically.
