A biоlоgist spent mаny yeаrs reseаrching the rate оf evolutionary change in the finch populations of a group of islands.

During the drought, there was a reduction in the number of plants producing thin-walled seeds. Which of the following best describes the mechanism behind the change in beak size in the finch population?
