A. Four postulates of natural selection, the outcome of which is evolution: 1. Individual organisms in a population vary in traits (size, shape, color, etc.). 2. Some variations in the population are heritable and can be passed on to offspring. 3. More offspring are produced than can survive; that is only a subset will survive to reproduce. 4.
