adaptation. 1. the adjustment of an organism to its environment, or the process by which it enhances such fitness. 2. the normal adjustment of the eye to variations in intensity of light. 3. the decline in the frequency of firing of a neuron, particularly of a receptor, under conditions of constant stimulation.
It is very simple: 1  Evolution is âdescent with modificationâ Populations of organisms change over the course of generations. 2  Adaptation is the result of one of the means of modification. Adaptation is the result of natural selection. Adaptations are the designs in plants and animals: eyes for seeing, oxidative phosphorylation for generating energy, flagella for movement, lungs for breathing, etc. There are other ways to modify populations over generations.
