Question

Homologous organs have ___ .

• A. similar origin but different functions
• B. similar origin and the same function
• C. different origin but same function
• D. different origin and different functions

Answer 1

The correct option is A similar origin but different functions

Homologous organs have similar origin, as a result they have similar structure but different functions. Examples - wings of a bat, flippers of whale and limbs of human beings. Whereas, wings of butterfly do not originate from the same common structure as the above mentioned ones so they are not considered to be homologous.
