Question

The wings of birds and butterflies is an example of:

• A. Divergent evolution
• B. Adaptive radiation
• C. Variation
• D. Convergent evolution

Hint:

Remember: Analogous organs → Convergent evolution.

Answer 1

The Correct Option is D

Concept: Convergent evolution occurs when unrelated organisms independently evolve similar structures or functions due to similar environmental pressures.
Step 1: Understanding the structures.
Wings of birds and butterflies serve the same function (flight) but have different structural origins.
Step 2: Nature of organs.
These are analogous organs — same function but different origin.
Step 3: Interpretation.
Such similarities arise due to convergent evolution.
Step 4: Evaluating the options.

• Divergent evolution $\rightarrow$ Same origin, different function (incorrect)
• Adaptive radiation $\rightarrow$ Evolution from common ancestor (incorrect)
• Variation $\rightarrow$ General differences (incorrect)
• Convergent evolution $\rightarrow$ Same function, different origin (correct)

Step 5: Conclusion.
Thus, wings of birds and butterflies are an example of convergent evolution.
