1. The Invention of Cooking

Humans have depended on fire for millennia, but do we fully understand the impact it has had on our diet? When our hunter-gatherer ancestors learned to harness this tool, it ignited a culinary and cerebral revolution believed to be one of the most important factors in our evolution.
