Question

Which of the following are analogous structure?

• A. Flippers of dolphin and legs of horse
• B. wings of bat and wings of pegion
• C. Gills of prawn and lungs of man
• D. Thorns of Bougainvillea and tendrils of Cucurbita.

Answer 1

The correct option is B wings of bat and wings of pegion

Bat wings consist of flaps of skin present between the bones of the fingers and arm.

Bird wings has feathers which can extend all along the arm.

These structural dissimilarities show that bird wings and bat wings were not inherited from a common ancestor with wings.

Bird and bat wings are analogous because they have separate evolutionary origins. But, they are superficially similar because they have experienced natural selection to make them act as a main part for flight.
