Why can analogous organs have similar functions?
Answer and explanation
Correct answer: Because they may develop from different structures for a similar need
Analogous organs perform similar functions but arise from different basic structures and evolutionary origins. Similar environmental demands can lead unrelated organisms to develop comparable adaptations, a process called convergent evolution. For example, a bird’s wing and an insect’s wing both help in flight, but their internal structures and origins differ. Hence, option A is correct. A shared ancestor, no function, or colour change does not explain analogy, so B, C, and D are incorrect.
