Question

Why are the wings of bats and wings of a bird called an analogous organ?

Answer 1

Hint: Analogous organs are those organs that have a different basic structure and developmental origin but they perform a similar function. These structures develop in unrelated organisms that exhibit convergent evolution.

Complete answer:
Wings of bat and Wings of bird and example of analogous organs. In the case of bat wings, they consist of a flap of skin stretching between the bones of the arm and fingers. Bird wings consist of feathers covering all over the arm.
From the diagram mentioned below, we can see that the bird’s wings and the bat wings were not inherited from a common ancestor. Bird and bat wings are called analogous because they have separate evolutionary Origins but they both perform a similar function which is a key role in flight.
Analogous organs are the result of convergent evolution. According to convergent evolution, it is a process in which organisms that are not closely related, independently evolve similar traits to adapt to a similar environment.

Note: Alike analogous organs, homologous organs are also found in which basic body design and structure are the same indicating towards the common origin but they perform a different function to adapt in different environments. For example, the forelimb of man and frog has the same basic design but they carry out different functions.
