Question

Forelimbs of cat/lizard used in walking, forelimbs of whale used in swimming and forelimbs of bats used in flying are examples of

• A. Adaptive radiation
• B. Homologous organs
• C. Convergent evolution
• D. Analogous organs

Answer 1

The correct option is B Homologous organs

The similarity based on common origin, the similar basic plan of organisation and embryonic development is called homology. The similarity in appearance and function is not necessary. The organs which have a common origin, embryonic development and same basic structure but perform different functions are called Homologous organ. The homologous term was given by Richard Owen.

So, the correct answer is 'Homologous organs'.
