Why are the human arm and bat wing homologous organs?
Answer and explanation
Correct answer: Because their basic bone structure is similar but functions are different
The governing concept is homology and common ancestry. The human arm is mainly adapted for grasping and handling objects, whereas the bat wing is adapted for flight. Despite this functional difference, both contain a corresponding arrangement of bones such as the upper arm, forearm and hand elements. Their similar basic structural plan indicates inheritance from a common ancestral limb, so they are homologous organs. The other options contradict their anatomy or definition.
