Although research on the nonverbal expression of emotion has played a prominent role throughout psychology during the past two decades-including an instrumental role in the development of contemporary evolutionary psychology-little research has focused on the evolutionary origins and functions of the emotional expressions themselves. However, recent findings from psychophysical, comparative, social, and cross-cultural psychology are converging to produce a compelling functionalist account, suggesting that emotional expressions serve critical adaptive purposes. Most of these studies have narrowly focused on single emotions-an approach that has been very useful for providing new insights about specific expressions but not for developing a broader understanding of why humans universally display and recognize distinct emotions. Here we unify these disparate findings in order to illuminate this fundamental form of social communication.
