WebNatural selection is working! WebThe mechanisms of evolution — like natural selection and genetic drift — work with the random variation generated by mutation. Factors in the environment are thought to influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but
