A PERSPECTIVE FROM EVOLUTIONARY PSYCHOLOGY

• Evolutionary psychology is an approach that
examines psychological traits from a modern
evolutionary perspective. It seeks to identify which
human psychological traits are
evolved adaptations – that is, the functional
products of natural selection or sexual selection.
