Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An example of an analogous structure includes:
A
wing of a butterfly and bird wing
B
bird wing and human arm
C
rat appendix and human appendix
D
None of the above
Explanation: 

Detailed explanation-1: -Analogies are similar characteristics shared by two different organisms because of convergent evolution. For example, the wing of a dove and the wing of a butterfly are analogous; the bird lineage and the insect lineage evolved wings independently of one another.

Detailed explanation-2: -Analogous organs are organs that have different anatomy but perform similar functions and have different origins. An example of an analogous organ is the wings of the insect and the wings of the bird.

Detailed explanation-3: -The wing of a bird and a butterfly wing are analogous structures, whereby the organisms do not share a common ancestral history.

Detailed explanation-4: -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.

Detailed explanation-5: -Analogous Organs: The organs of different animals that have distinct structure but perform similar functions are called analogous organs. Examples of such organs are the wings of the insect and the wings of the bird.
