Homologous organs are those organs which have the same basic structure (or same basic design) but different functions. Hence, they have common ancestor or origin. Analogous organs are defined as the organs of different animals that are having different structure but perform the same functions.

Eyes of octopus and mammals are an example of convergent evolution because they both have different anatomical structures of eyes but perform the same function and hence having similarity.
