What can indicate a common ancestor in evolution?
Answer and explanation
Correct answer: Homologous organs
Homologous organs can indicate common ancestry because organisms may inherit a similar underlying structural plan from an ancestral form. Their present functions may differ as populations adapt to different conditions, but the corresponding arrangement of parts remains evidence of relationship. Therefore option A is correct. Shared colour, food, or location alone does not reliably establish ancestry and cannot replace structural or genetic evidence.
