Add note that natural selection is not evolution, though often treated synonymously
The fundamental statement of '''natural selection''' is that heritable traits which are beneficial will tend to become more numerous in successive generations, while heritable traits which are harmful will tend to become more scarce. The traits are defined to be beneficial if they become more numerous in successive generations. This principle is general, and applies to any system of individuals which reproduce; it is most commonly applied to systems of living organisms. It is sometimes summarized by the slogan, ''survival of the fittest''.
