A PERSPECTIVE FROM EVOLUTIONARY PSYCHOLOGY
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.

which genes are propagated into future
generations, sexual selection plays a large role in
the direction of human evolution.
