Origins of Language: A Slim Guide offers a concise and accessible overview of what is known about the evolution of the human capacity for language. Non-human animals communicate in simple ways: they may be able to form simple concepts, to feel some limited empathy for others, to cooperate to some extent, and to engage in mind-reading.

After the first simple beginnings, human language underwent an explosion of complexity, leading to the very complicated systems of grammar and pronunciation found in modern languages.
