Inventing Fire: the First Spark of Humanity
Summary
Host Dallas Campbell interviews anthropologist Richard Wrangham about his theory that cooking with fire drove human evolution. Wrangham explains how digesting cooked food allowed for smaller guts and larger brains, fundamentally changing our anatomy two million years ago. The discussion also covers why other animals haven’t mastered fire and touches on Wrangham’s newer research into human cooperation and aggression.
