What is the strongest basis for considering a bird wing and an insect wing analogous?
Answer and explanation
Correct answer: Their function of flight is similar, but their basic structures are different
Analogy is identified by similar function combined with different evolutionary and structural origins. Both bird and insect wings enable flight, but a bird wing is a modified, bony vertebrate forelimb, whereas an insect wing is a different external structure without the same bone plan. Thus option A is correct. Options B, C, and D contradict these anatomical facts.
