Question

Which one correctly describe homologous structures?

• A. Organs with anatomical similarities but, performing different functions
• B. Organs with anatomical dissimilarities but performing same function
• C. Organs that have no function now but had an important function in ancestors
• D. Organs appearing only in embrycnic stage and disappearing later in the adult

Answer 1

The correct option is A Organs with anatomical similarities but, performing different functions

• Homologous organs are the organs which have a similar structure (anatomical similarities) and different function and have the same developmental origin. For example, wings of birds and fore-limbs of the horse.
  
• Hence organs with anatomical similarities but, performing different function correctly describe homologous structures.
• So, the correct answer is 'organs with anatomical similarities but, performing different functions'.
