The wings of a bird and the wings of an insect are

A phylogenetic structures and represent divergent evolution
B homologous structures and represent convergent evolution
C homologous structures and represent divergent evolution
D analogous structures and represent convergent evolution.

Verified Solution

Answer & Solution

Correct Answer

(D) analogous structures and represent convergent evolution.

Step-by-step Solution

Detailed explanation

(d) : Analogous organs are the organs which have similar function but are different in their structural details and origin. The analogous structures are the result of convergent evolution. The wings of an insect are analogous to wings of a bird because the basic structure of the wings of the insects is different from the wings of bird. However, their function is similar.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
