How Ancient Humans Knew What Was Safe to Eat

There's a list inside your head right now of foods that are safe and foods that aren't — and you never built it. Somebody else did, a very long time ago, and most of them didn't survive making it. In this video, we explore how early humans figured out what was safe to eat with no labels, no science, and no internet to check — using a method called the "sampling strategy," learning from animal behavior, and eventually building cultural food rules that still shape what you eat today. We also dig into one of history's strangest and most overlooked food disasters: ergotism, a fungal contamination of medieval rye that caused widespread convulsions and hallucinations across entire villages.
