Vedclass · Answer

(A) Analogous organs are those that perform similar functions but have different evolutionary origins and anatomical structures.$1$. Wings of a butterfly (insect),housefly (insect),and bat (mammal) all serve the purpose of flight.$2$. While the wings of the butterfly and housefly are membranous outgrowths of the exoskeleton,the wings of a bat are modified forelimbs supported by bony structures.$3$. Since they perform the same function (flight) but have different embryonic origins,they are considered analogous organs.$4$. The other options listed (hind legs,hands,mandibles) represent homologous organs,which share a common ancestral origin but may perform different functions.

Which one of the following sets of structures includes only analogous organs?
