Importance of Variations:
1. Variations make some individuals better fitted in the struggle for existence.
2. They help the individuals to adapt themselves according to the changing environment.
3. Discontinuous variations produce new traits in the organisms.
4. Variations allow breeders to improve races of useful plants and animals for increased resistance, better yield, quicker growth and lesser input.
5. They constitute the raw material for evolution.
6. Variations give each organism a distinct individuality.
7. Because of variations, species do not remain static. Instead, they are slowly getting modified forming new species with time.
8. Pre-adaptations caused by the presence of neutral variations are extremely useful for survival against sudden changes in environment, e.g., resistance against a new pesticide or antibiotic.
