Why Humans Can Eat Anything (But Animals Can’t)

Why can humans eat almost anything while most animals can't? A koala can starve in a forest full of leaves. One headache pill can kill a cat. Yet you eat bread, cheese, chili and fermented food every day. The real reason isn't a stronger stomach. It's fire, stone tools, gut bacteria, milk and starch genes, and food knowledge passed down for a million years. In this video: - Why koalas, pandas and cats are trapped by their diets - How cooking became our "outside stomach" - Why your stomach acid is closer to a vulture's - How famine spread the milk gene - Why a cracker turns sweet in your mouth - Why picky toddlers run ancient survival software - How Burke and Wills starved on full stomachs Key researchers: Paul Rozin (omnivore's dilemma), Richard Wrangham (cooking hypothesis), Daniel Lieberman & Katherine Zink, Leslie Aiello & Peter Wheeler, Richard Evershed & Mark Thomas, Joseph Henrich, Hans Rosling, John Garcia.
