Natural selection is often portrayed by laymen is a black-and-white process, a process that acts by killing off all less fit organisms. Fitness itself is often portrayed by these same laymen as referring to an organism's health, strength, intelligence, speed. Neither is correct. Natural selection is a stochastic process: it works through averages. And it doesn't work by killing off less-fit organisms only: it works through reproductive success; the average chance of an organism raising fertile offspring. And fitness refers only to the average reproductive success that a particular combination of traits proffers.
