Why did Eurasians conquer, displace, or decimate Native Americans, Australians, and Africans, instead of the reverse? In this groundbreaking book, evolutionary biologist Jared Diamond stunningly dismantles racially based theories of human history by revealing the environmental factors actually responsible for history's broadest patterns. Here, at last, is a world history that really is a history of all the world's peoples, a unified narrative of human life even more intriguing and important than accounts of dinosaurs and glaciers. A major advance in our understanding of human societies, Guns, Germs, and Steel chronicles the way that the modern world, and its inequalities, came to be. It is a work rich in dramatic revelations that will fascinate readers even as it challenges conventional wisdom.
