An analogous structure is a structure that has a similar function but different components. For example, the wings of a butterfly verses those of a bird. In both cases, the fu â¦ nction is flight, but the wings are build differently.
To From Subject Comments. Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common functionâflying.
