Jared Diamond's New York Times best-selling Guns, Germs, and Steel won the Pulitzer Prize. In The World Until Yesterday, Diamond holds a mirror up to modern society by examining traditional cultures such as the New Guinea Highlanders, the Inuit, and the Amazonian Indians. In a relatively short period of time, these cultures have largely disappeared—but Diamond believes they may still offer humanity lessons on how to live and survive as societies grow and evolve.
