Natural selection is rhe sirvival of the fittest. The fittest for the environment. If there is a sudden change in the environment say for example, flood or forest fire, etc. , species that once thrived may no longer have what it takes to survive in the changed environment. Other species might find it easier to thrive in the changed environment.
