<h3>In seedcracker finches from Cameroon, small- and large-billed birds specialize in cracking soft and hard seeds?</h3>

In seedcracker finches from Cameroon, small- and large-billed birds specialize in cracking soft and hard seeds, respectively. If long-term climatic change resulted in all seeds becoming hard, what type of selection would then operate on the finch population?
Answer
disruptive selection
stabilizing selection
directional selection
No selection would occur because the population is in Hardy-Weinberg equilibrium.
