Question

Which of the following are homologous organs?

• A. Human eye and squid eye
• B. Gills of fish and lungs of man
• C. Forelimbs of man and wings of bat
• D. Sting of bee and scorpion

Answer 1

The correct option is C

Forelimbs of man and wings of bat

The forelimbs of man and bat are anatomically similar in that they have similar bones including the humerus, radius, ulna, carpals, metacarpals and phalanges. However, these structures have been collectively modified into forelimbs in man and wings in bat, performing different functions. The human forelimbs are meant to perform different kinds of physical activities, while the bat wings are used for flight. The human eye and squid eye, the gills of fish and lungs of man, and the stings of bee and scorpion are all examples of analogous organs, which are structurally different and functionally similar.
