1)Well-adapted individuals leave more offspring than do poorly adapted individuals.
2)A change occurs in the environment.
3)Genetic frequencies within the population change.
4)Poorly adapted individuals have decreased survivorship.
A)2 → 4 → 1 → 3
B)4 → 2 → 1 → 3
C)4 → 1 → 2 → 3
D)4 → 2 → 3 → 1

The correct sequence under the influence of natural selection starts with a change in the environment (2), leading to decreased survivorship of poorly adapted individuals (4). Well-adapted individuals then leave more offspring than poorly adapted ones (1), resulting in a change in genetic frequencies within the population (3).
