Question

In the animal kingdom, flippers of penguin and dolphin are analogous organs because they:

विकल्प

• Perform the same swimming function but have different structural origins

• Evolved from the same ancestral limb structure

• Have identical internal bone structures and origins

• Are found in the same geographic location

Answer 1

Penguin flippers and dolphin flippers are analogous because both function for swimming locomotion despite having entirely different origins. Penguin flippers are modified bird wings derived from forelimbs with feathers, while dolphin flippers are modified mammalian forelimbs with bones. They represent convergent evolution in unrelated vertebrate groups adapting to aquatic environments.
