Final answer:

Directional selection by pollinators can drive the evolution of larger flowers by favoring traits that enhance reproductive success, leading to mutual coevolution between flowers and pollinators.


Explanation:

Directional selection imposed by pollinators could be a possible evolutionary mechanism producing larger flowers. Natural selection favors traits that enhance reproductive success. In the case of pollinators, larger flowers may attract specific pollinators more effectively, leading to increased pollination success.

This process can result in an increase in the frequency of genes associated with larger flower size, as seen in the example of birds with longer beaks evolving to access sugary food sources from deeper flowers.

Through mutual coevolution, flowers and pollinators develop characteristics that benefit each other, illustrating the impact of directional selection by pollinators on flower size and traits.
