Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion (A) : Homology indicates common ancestry of different species.

Reason    (R)  : Homologous organs have similar anatomical structures.

In light of the above statements, choose the correct answer from the options given below.

Both (A) and (R) are true and (R) is the correct explanation of (A).  

• Assertion (A) is true. Homology does indeed indicate the common ancestry of different species. Homologous structures are features that are similar in structure and position but may have different functions. The similarity in structure suggests that these features were inherited from a common ancestor.
• Reason (R) is true. Homologous organs have similar anatomical structures and perform different functions. Homologous organs do indeed have similar anatomical structures. This similarity in structure is indicative of a common evolutionary origin, suggesting that these organs were inherited from a common ancestor. Therefore, Reason (R) correctly describes the anatomical aspect of homologous organs.
