Question

which of the following describes the most likely scenario for how one of the adaptations described in the passage became common in galápagos finches? choose 1 answer: a the thin beak trait became common in green warbler - finches because it helped them migrate to new areas when resources were scarce. b the green color trait became common in large ground finches because it provided camouflage from predators in their habitat. c the thick beak trait became common in large ground finches because it allowed them to crack open abundant, thick - shelled seeds in the environment. do 10

Explanation:

To determine the correct answer, we analyze each option based on evolutionary adaptation principles (natural selection):

• Option A: A thin beak is related to feeding (e.g., insect - eating or nectar - sipping), not migration. So this is incorrect.
• Option B: Large ground finches are not green (they are typically brownish - gray), and their survival is more related to feeding adaptations (beak shape) than camouflage via green color. So this is incorrect.
• Option C: Large ground finches' thick beaks are an adaptation for cracking thick - shelled seeds. If thick - shelled seeds are abundant, finches with thick beaks would have a survival advantage (able to access food), and over time, this trait would become more common due to natural selection. This matches the concept of adaptation.

Answer:

C. The thick beak trait became common in large ground finches because it allowed them to crack open abundant, thick - shelled seeds in the environment.
