Question

Which of the following is an example of homologous structures that provide evidence for evolution?

• A. Wings of a bird and wings of an insect
• B. Forelimbs of a human and wings of a bat
• C. Fins of a fish and flippers of a whale
• D. Stingers of a bee and spines of a porcupine

Hint:

Distinguish homologous structures (same origin, different functions) from analogous structures (different origins, similar functions). Homologous structures, like vertebrate forelimbs, support common ancestry.
