Analogous structures include the wing of a butterfly and the wing of a bird. How are butterfly and bird wings different? The two types of wings share a common function (and therefore are both called wings), but the bird wing and insect wing did not arise from an original ancestral structure that became modified through evolution into bird wings and butterfly wings. Although analogous structures perform the same functions, they are not related. c. Radial body symmetry. Breeders use___to enhance desired traits in domesticated plants and animals. In terms of structure, bird wings are filled with hollow bones for easier flight, whereas butterfly wings are structured by scales and tiny hairs.
