Homologous structures: Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous. Radial body symmetry. Some structures are both analogous and homologous: bird and bat wings are both homologous and analogous. Therefore, for example, the wing of a butterfly and the wing of a bird are analogous. Analogous structures are organs or parts of the body where, even though the function (and maybe even the shape) of the organ is similar, there is a very different underlying bone or muscle structure. 1. 2. 2 Are bat wings and butterfly wings homologous or analogous structures?
