Expressly Human
Decoding The Language of Emotion

Why did once-stone-faced animals evolve to be so emotionally expressive—to be us? Expressly Human introduces an original theory that explains, from first principles, how the broad range of emotional expressions evolved, and provides a Rosetta Stone for human communication. It will revolutionize the way you see every social interaction, from deciding who gets the last slice of pizza to multimillion-dollar business negotiations, and change your definition of what makes us human.
