In biology:
* Adaptation is the process by which organisms evolve over time to become better suited to their environment. This involves changes in their physical characteristics, behaviors, and/or genetic makeup.
* Adaptive trait is a feature that helps an organism survive and reproduce in its environment.
In other contexts:
* Adaptation can also refer to the act of adjusting to a new situation, such as when people adapt to a new culture or technology.
* Adaptation in literature and film refers to the process of changing a story or work of art to fit a different medium or audience. For example, a novel being adapted into a movie.
Here are some examples of adaptation:
* Biological: A polar bear's thick fur and blubber are adaptations for living in cold climates.
* Cultural: A new immigrant learning the local language and customs is an example of cultural adaptation.
* Literary: The film "The Lord of the Rings" is an adaptation of the novel by J.R.R. Tolkien.
It is important to note that adaptation can be a gradual process that happens over generations in the case of biological evolution, or it can be a rapid change that occurs within an individual's lifetime in the case of cultural or technological adaptation.
