The wings of a bird and the wings of a butterfly are an exam...

Although both serve the same function (flight), their evolutionary origins are completely different. Bird wings are modified forelimbs of vertebrates, whereas butterfly wings are extensions of the insect exoskeleton. Since these wings evolved independently for the same function (flight), they are analogous.

For A: Homologous structures are those that share a common evolutionary origin, even if their functions differ. The wings of a bird and the wings of a butterfly do not share a common evolutionary origin (they evolved from very different ancestral structures), so they are not homologous.

For C: Convergent evolution refers to the process where differ...
