Question

Forelimbs of frog and lizard are the example of the ............ organs.

• A. Homologous
• B. Analogous
• C. Both A and B
• D. None of these

Answer 1

The correct option is A Homologous

• The homologous organs are similar in form but perform different functions in different organisms.
• The bone structure observed in wings of birds, forelimbs of lizard and frog is similar, but perform different functions. They belong to the same group of animals, the vertebrates and therefore exhibit homology.
• Homology in animals - Organs such as bat's wing, wings of birds, seal's flipper, forelimb of a horse, and human arm have a common underlying anatomy that was present in their last common ancestors; therefore their forelimbs are homologous organs.
