Evolutionary psychology offers an important perspective to scientific psychology. Evolutionary psychology, in its short existence, has added an abundance of knowledge to the social sciences, let alone psychology. The study of human cognition and behavior remains incomplete without an evolutionary perspective. Here, we argue that evolutionary psychology uniquely provides a complete understanding of scientific psychology because it explains the functions of our psychological traits, provides us with the most parsimonious explanation of many psychological phenomena, predicts undocumented phenomena, and possibly allows us to avoid the downfalls of some of our contemptible evolved psychological mechanisms.
