The relationship between language, thought and culture is of concern to anyone with an interest in what it means to be human. ‘The Language Puzzle’ explains how the invention of words at 1.6 million years ago began the evolution of human language from the ape-like calls of our earliest ancestors to our capabilities of today, with over 6000 languages in the world and each of us knowing over 50,000 words. Drawing on the latest discoveries in archaeology, linguistics, psychology, and genetics, Mithen reconstructs the steps by which language evolved. While this radical new work is not shy to reject outdated ideas about language, it builds bridges between disciplines to forge a new synthesis for the evolution of language that will find widespread acceptance as a new standard account for how humanity began.
