NEET2024Biology
Q.

The flippers of the penguins and dolphins are the example of the:

  1. A

    Convergent evolution

  2. B

    Divergent evolution

  3. C

    Adaptive radiation

  4. D

    Natural selection

Solution

Penguin flippers (a bird's modified forelimb) and dolphin flippers (a mammal's modified forelimb) evolved independently in unrelated lineages for the same aquatic function. Structures arising independently for similar functions are called analogous structures, and this phenomenon is convergent evolution.
