New in paperback. Hardcover published in 2018. Debunking long-held theories across a spectrum of disciplines, Daniel L. Everett, a "bombshell" linguist and "instant folk hero" (Tom Wolfe, Harper's), presents the stunning ideas that we are not born with an instinct for language and that the near seven thousand languages that exist today - the product of one million years of evolution - are the very basis of our own consciousness. Woven throughout with lucid anecdotes of his nearly forty years of fieldwork among Amazonian hunter-gatherers, this exploration of our humanity becomes a landmark study of what makes us human.
