Q. Can the wing of a butterfly and the wing of a bat be considered homologous organs? Why or why not?
No, the wing of a butterfly and the wing of a bat can not be considered homologous organs because they both perform the same function of flying but their origin and structure is not similar. The bird’s wing has well developed bone structure supported with flesh and feathers whereas insect’s wing has evolved from hardening of membrane cover with a few associated muscles. Homologous organs have similar basic structure but perform different functions, where as analogous organs have different origin and structure but perform same functions.
