Question

Which of the following is not an example of organs showing convergent evolution?

• A. Wings of butterfly and birds
• B. Sweet potato and potato
• C. Eye of Octopus and mammals
• D. Forelimbs of whales and bats

Answer 1

The correct option is D Forelimbs of whales and bats

Forelimbs of whales and bats exhibit homology/divergent evolution.

Development of similar adaptive functional structures in unrelated groups of organisms is called convergent evolution. It shows analogy. Examples are wings of butterfly and birds, eye of octopus and mammals, flippers of penguins and dolphins, modification of sweet potato and potato, etc.

On the other hand, divergent evolution involves the modification of organs to perform different functions as an adaptation to different environments. For example forelimbs of vertebrates (whales, bat, cheetah, human). Though these perform different functions, they have similar anatomical structure.

So, the correct answer is 'Forelimbs of whales and bats'.
