The document discusses evolutionary psychology and emotions. It argues that the brain evolved specialized programs to solve adaptive problems, and that emotions evolved as superordinate programs to manage these other programs in recurrent ancestral situations. Emotions help coordinate physiology, feelings, and behavior. Facial expressions of emotions also evolved to communicate mental states to others in ways that were reliably informative over human evolution. Some emotions are more readily expressed than others depending on the selection pressures of different ancestral situations.
