Detailed explanation-1: -genetic drift. In a population of lizards, the smallest and largest lizards are more easily preyed upon than medium-sized lizards. What kind of natural selection is MOST likely to occur in this situation? natural selection.

Detailed explanation-2: -12.In what type of selection do individuals of average size have greater fitness than small or large individuals?-Stabilizing selection 13.

Detailed explanation-3: -In stabilizing selection, the average size of individuals in the population does not change. After many generations, however, there are fewer very large lizards and fewer very small lizards. Stabilizing selection favors intermediate phenotypes.

Detailed explanation-4: -For more than a century, scientists have understood that natural selection have profound effects on how an animal looks–Anolis lizards that spend more time on the ground, for example, might need longer legs for running, while species that remain in the trees usually have shorter legs better suited for climbing.
