Catching Fire: How Cooking Made Us Human

Catching Fire: How Cooking Made Us Human by Richard Wrangham

Humans adopted cooking. Then evolution move to favor those that cooked food. Cooking food allowed humans to devote fewer resources to the digestive system and more to other areas. This helped humans to later dominate. Today there are some people that advocate "raw" diets. However, these diets are rare and often result in caloric deficiencies. They also often require use of food that has been processed in some ways. Humanity's ancestors were likely able to live on this raw food, but today, people are quick to move towards cooking.
