How Did Ancient Humans Know What Was Safe to Eat?

You ate something this morning without a second thought. But somewhere in your ancestry, a person with no labels, no guidance, and no second chances had to figure out if that food would kill them. How did they get it right? The obvious answer — trial, error, and observation — doesn't hold up. The real story involves a biological learning system more sophisticated than anything we've built, a behavioral ecologist who discovered it by studying sheep, and a mechanism running in your body right now that your conscious mind knows nothing about. Nudge makes videos about the hidden mechanics of the world — the counterintuitive, the overlooked, the genuinely strange.
