adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection ’s acting upon heritable variation over several generations.

Review your understanding of adaptation and environmental change in this free article aligned to NGSS standards.
•Populations are often affected by changes in their environment. For example, changes in climate can affect how easy it is for organisms to find food or water.
•After an environmental change, traits that help organisms survive and reproduce in the new environment become more common. Similarly, traits that make organisms less likely to survive and reproduce become less common. This process occurs over multiple generations.
•As helpful traits become more common, the population adapts, or becomes better suited, to the new environment. The increase in helpful traits in a population over generations describes adaptation by natural selection.
•If environmental changes are too extreme, populations do not have time to adapt. As a result, the populations may go extinct.
An adaptation is a feature that arose and was favored by natural selection for its current function. Adaptations help an organism survive and/or reproduce in its current environment.
Definition: Reciprocal transplant experiment.
v. t. e. In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
