On an island, different food sources lead to different beak adaptations in birds. Which process can this show?

Answer and explanation

Correct answer: Adaptive radiation

Adaptive radiation occurs when one ancestral group gives rise to several forms that become adapted to different ecological niches. On an island, bird populations facing different foods may be favored for different beak shapes and feeding abilities. Over many generations, these divergent adaptations can produce multiple related forms. Therefore option A is correct; sex determination, self-pollination, and test crossing do not describe this ecological diversification.
