Evolutionary Theories

Definition

Evolutionary theories are explanations or frameworks that use principles of natural selection and adaptation to understand how certain traits, behaviors, or characteristics have developed and persisted over time within a species.

Analogy

Think of evolutionary theories as road maps that help us navigate the complex journey of understanding why certain traits or behaviors exist in different species. Just like a road map helps us find our way from point A to point B, evolutionary theories guide scientists in uncovering the reasons behind the existence and persistence of specific traits.
