Which of the following is a pair of analogous organs?

• A) Wing of the bird and flipper of whale
• B) Fore limbs of horse and man
• C) Wing of bird and forelimb of horse
• D) Wing of insect and wing of bird

Analogous organs are those that serve similar functions but have different evolutionary origins. In the options provided, the correct pair of analogous organs is:

Correct Answer

A) Wing of the bird and flipper of whale

Explanation

The wing of a bird and the flipper of a whale both enable flight and swimming, respectively, but they evolved from different ancestral structures. In contrast:

• B) Fore limbs of horse and man: These are homologous organs, sharing a common ancestor.
• C) Wing of bird and forelimb of horse: These are also homologous, as they have similar bone structures.
• D) Wing of insect and wing of bird: While they serve the function of flight, they are not directly comparable as they evolved independently.

Thus, the best example of analogous organs from your options is the wing of the bird and the flipper of the whale.
