Why We Are The Only Species That Cooks

You stare at your microwave, annoyed that it takes two full minutes to heat up your dinner. But did you know that hot meal is the exact reason you have the brain capacity to complain in the first place? In this episode of Primal Canvas, we explore Richard Wrangham's "Cooking Hypothesis" and how taming fire didn't just change our diet—it completely rewired our biology. We shrunk our guts, expanded our brains, and built the world's first social network around a campfire.
