Answer:
Directional selection
Explanation:
Directional selection is a mode of natural selection in which <u>a phenotype is favoured among other phenotypes </u>and therefore the population with the phenotype favoured increases over time to optimize their chances of survival.
This selection usually <u>requires a force in nature that causes a population to evolve towards one end of a trait spectrum.</u>
In this example, dark-colored moths are selected by predators because they stand out to predators against the light-colored foliage. Therefore, <u>this force in nature causes moths to change their phenotype and it shifts away from the dark-colored phenotype in order to increase their chances of survival so that predators do not predate them as easily because they won't stand out against the light-colored foliage. </u>

Thus this is an example of directional selection.
