is there bones in a butterfly wing
However, their wings are quite different on the inside. Bird wings have an internal framework consisting of bones, while butterfly wings do not have any bones at all and are kept rigid mostly through fluid pressure. Analogies may be due to homologies or homoplasies, but the common ancestor, if any, is unknown.nalogies are anatomical features that have the same form or function in different species that have no known common ancestor. For instance, the wings of a bird and a butterfly are analogous structures because they are superficially similar in shape and function.
