Question

In seedcracker finches on a remote island, birds are found with varying bill sizes. Those with larger bills (on average) specialize in cracking hard, thick-walled seeds. Birds with smaller bills (on average) feed on seeds with softer seed coats. If ongoing climate change results in the most of the seeds in the area becoming thich-walled, predict the outcome on the population of seedcracker finches. Select ALL that apply.

Directional selection will drive the population of finches to have larger bills.

Natural selection will reduce the frequency of those birds with small-billed phenotypes.
