1. Differences in characters within very closely related groups of organisms are referred to as variations.
2. Variations developed during reproduction in organisms.
3. Variations are passed from parent to offspring through heredity.
4. Beneficial variations are selected by the nature in evolution.
5. Variations increases the survival chance of the organisms.
6. These variations in organisms adapt to their environments.
7. For example green colour in the Beetles is a variation that give survival advantage to the Beetles as they cannot be seen by the crows.
8. Some variations do not help organisms to survive. For example colour variation occurs in red beetles and some blue beetles are produced instead of red beetles as they are eaten by crows easily.
