Variations can be beneficial or harmful according to the ecological niche of the organism. A variation suitable for the particular niche is selected by nature in evolution. Thus variations are necessary for the survival of the species. Variation is important for evolution of the species.

E.g.: A population of heat resistant bacteria in temperature of the water survives, if the temperature of water increases by global warming but most other bacteria would die.
