Variation. In evolution, the fate of an individual depends on which features it has. Each human, for example, inherits a unique combination of thousands of different features, such as eye color, blood type and sensitivity to certain tastes. Some variants, or versions of a feature, may help an organism to survive. Others may be harmful.
