Final answer:

Directional selection shifts population towards larger organisms due to environmental changes.


Explanation:

Directional selection occurs when a population experiences a shift towards larger organisms due to environmental changes. This type of selection favors individuals at one extreme of the population, leading to changes in the average phenotype over time.

For example, if a species of birds with larger beaks is favored due to the availability of larger seeds, directional selection will lead to an increase in the frequency of larger-beaked birds in the population.

Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, leading to the maintenance of genetic diversity within a population.
