Harvard biological anthropologist Richard Wrangham argues that fire and cooking is what made humans human. His "cooking hypothesis" says Homo erectus evolved bigger brains 1.8 million years ago because cooked food required less energy to digest, freeing calories…
🔥 Richard Wrangham's new book, "Catching Fire: How Cooking Made Us Human," argues that cooking, not agriculture or meat-eating, is the primary driver of human evolution.
🧠 The ability to cook food, harnessing fire, allowed human brains to grow and digestive tracts to shrink, leading to the emergence of Homo erectus around 1.8 million years ago by providing more calories and less energy spent on digestion.
👨👩👧👦 Cooking also profoundly impacted social structures, fostering paired mating, domestic roles, and food distribution within families, with humans being biologically adapted to cooked food today.
