Adaptations are inheritable characteristics that increase an organism's ability to survive and reproduce in an environment. Adaptations can help an organism find food and water, protect itself, or manage in extreme environments. Adaptations develop gradually over long periods of time and through many generations of the species. Individuals with characteristics that are advantageous are usually the survivors who live on to reproduce and contribute offspring to future generations.
