If a few birds reaching an island have variation in beak size, what may happen because of different food sources?
Answer and explanation
Correct answer: Groups with different beak types may adapt and diverge
Beak-size variation can affect how efficiently birds use different food sources. If a particular beak gives better access to available food, birds having it may survive and reproduce more successfully. Over many generations, natural selection can make populations using different resources increasingly distinct. This is a possible example of adaptive radiation. Therefore option A is correct; the other choices deny inheritance, selection or environmental influence.
