Question

Homologous organs have:

• A. Similar origin but different functions
• B. Similar origin and 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

$\bullet$ 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.
$\bullet$ If we compare wings of butterfly to wings of a bat, they do not originate from the same common structure despite performing similar function so they are not considered to be homologous.
