Evolutionary psychology is a theoretical approach within the field of psychology that seeks to understand how evolutionary principles, such as natural selection, shape human behavior and mental processes. It posits that many psychological traits and behaviors have evolved to solve recurring problems faced by our ancestors, influencing aspects of cognition, emotion, and social interactions. This perspective emphasizes the role of inherited traits in understanding human nature and examines how evolutionary factors can help explain modern behaviors, including mate selection, parenting, aggression, and cooperation.
