Answer :
Because the drought restricted the number of seeds available, finches with larger beaks were able to consume the larger, harder seeds, resulting in a higher survival rate.
Natural selection, which is produced by trait inheritance, individual competition, and trait variation, results in differences between species.
Explanation:
Individuals with hereditary features that enable them to compete better would survive and have more offspring than those with variants that make them less competitive.
Huge-billed finches eat large, hard seeds more efficiently, whereas smaller-billed finches eat small, soft seeds more efficiently.
