Question

Which one of the following are analogous structures ?

(a) Wings of bat and wings of pigeon 

(b) Gills of prawn and lungs of man 

(c) Thorns of Bougainvillea and tendrils of Cucurbita 

(d) Flippers of dolphin and legs of horse

Answer 1

Correct option (a) Wings of bat and wings of pigeon

Explanation

Analogous organs are the structures of different species having similar or corresponding functions but different structure. They do not belong to the same evolutionary origin. 

Wings of bat are skin folds stretched mainly between elongated fingers but the wing of birds are feathers covering all along the arm. They look similar because they have a common use for flying, but their origin is not common.
