Question

The following image represents the wing of a bat and bird. Which among the following statements are correct with respect to the image?

• A. The have same origin
• B. They are analogous structures
• C. They have same function
• D. They are homologous structures

Answer 1

Answer: (B), (C)

They have same function

The organs which have similar functions but are different in their structural details and origin are known as analogous organs. Wings of a bat are analogous to the wings of a bird. They are structurally dissimilar as wings of bats are skin folds stretched between elongated fingers. On the other hand, wings of a bird are feathery coverings all along the arm. Both of them do not have the same origin as well. But they have a common function, i.e., flying. Hence, wings of bird and bat are analogous structures.
