If two organisms have organs with different functions but similar basic structure, what can these organs indicate?
Answer and explanation
Correct answer: Homologous organs and common ancestry
The governing concept is homology in evolution. Organs such as the forelimbs of humans, whales and bats may have different functions, yet their underlying bone arrangement is similar because they were inherited from a common ancestral structure. Therefore, option A is correct. Analogous organs have similar functions but different structural origins, while acquired traits and food habits do not explain this anatomical pattern.
