a: natural selection ~
b: a sieve
What:
"The mutations are random. Natural selection is like a sieve. Those genes that produce an organism that is well suited to the environment will be more likely to reproduce than those that are less well suited. Those genes will tend to dominate in a population. If the environment changes the gene pool changes by the process I just mentioned. "
