Food. It's driven nearly everything we've ever done as a species, and yet it's one of the most overlooked aspects of human history. First, our hunger drove us to hunt, then to plant and settle, resulting in civilization. As humans became more sophisticated, so did our needs, and we searched for flavor and convenience. Whether for meat or sugar, junk food or beer, humanity's appetite has appetite has altered the planet, shaped our history and even changed our future. National Geographic explores the epic story behind food and how it made us who we are today.
