Catching Fire: How Cooking Made Us Human

Wrangham convincingly demonstrates how strange human biology and eating habits have become - we have extremely small mouths relative to our closest relatives, we spend a shockingly small amount of time chewing, etc. This book argues that these evolutionary changes were most likely brought about by the adoption of cooking, working through alternative hypotheses and systematically dismantling them. By combining archaeological, anthropological, chemical, and experimental evidence, by the end of this book one gets a comprehensive view of the factors that drove humans to the state we're in today. Highly recommend.
