Vedclass · Answer

(B) Homologous structures are those that have the same anatomical origin and basic structural plan but may perform different functions. $1$. The wing of a bird and the forelimb of a rabbit (or human/bat) share the same skeletal elements (humerus,radius,ulna,carpals,metacarpals,and phalanges),indicating a common ancestral origin. $2$. Therefore,the forelimb of a rabbit is homologous to the wing of a bird. $3$. Wings of a moth and wings of a bird are analogous structures as they perform the same function (flight) but have different evolutionary origins. $4$. Flippers of a whale and dorsal fins of a shark are also examples of analogous structures.

Which of the following structures is homologous to the wing of a bird?
