Question

what is an analogous structure?
a structure that used to serve a purpose but does not have a purpose in modern species
a structure that has the same function but different forms like the wing of a bee and wing of a bat
a structure that has the same form but different functions like an arm, fin, and wing

Explanation:

Analogous structures are those that have similar functions but different evolutionary origins and anatomical forms. For example, the wing of a bee (an insect) and the wing of a bat (a mammal) both are used for flight (same function) but have different underlying structures (different forms). The first option describes a vestigial structure. The third option describes homologous structures.

Answer:

a structure that has the same function but different forms like the wing of a bee and wing of a bat
