How Did Ancient Humans Know What to Eat — Without Dying First?

There were no labels. No guides. No one to ask. Just thousands of plants on the ground, and one question your ancestor had to answer with his own body: is this going to feed me, or end me? How did early humans tell food from poison when every berry looked the same? Why does bitterness still make you flinch — even when you know the coffee is safe? And what did it cost, in real lives, to build the knowledge you now take for granted every time you open your mouth? We look at the methods your ancestors used to sort the edible from the lethal — watching animals, tasting in micro-doses, reading their own pain — and how every flavor you experience today is a survival report written in someone else's suffering. On Old Bones we explore the ancient decisions that made us who we are — the hunts, the tools, the ideas that your body still carries today. SOURCES: TASTE & CHEMICAL ECOLOGY ▸ Johns, T. (1990).
