Adaptation & Natural Selection
Populations in a particular environment that have adapted to living conditions in that specific area are therefore better able to meet their survival needs and are more likely to survive and reproduce offspring with those key survival traits.
- An adaptation is a trait or behavior that helps an organism survive and reproduce.
- Traits are genetic differences that occur in a species. Traits are developed as a species adapts to its environment.
- Organisms of a species differ from one another in many of their traits.
- There can also be variations among species of similar populations. Variations are changes in the genes among members of the same species.
- Variations can occur both randomly and as a result of a trait being more fit for an environment.
- Natural selection is the process that explains this survival and shows how species can change over time.
- For example, certain traits or adaptations involving color, camouflage, food gathering (beaks and claws) and other physical traits, sensory abilities, or behaviors enhance the survival of a species.
