If two organisms are more similar, what can be inferred about them?
Answer and explanation
Correct answer: Their evolutionary relationship may be closer
The governing concept is comparison of biological features as evidence of relatedness. When organisms share more structural, biochemical or genetic similarities, they often have a more recent common ancestor and may therefore have a closer evolutionary relationship. However, similarity alone does not prove that they belong to the same species; reproductive compatibility and other evidence may also matter. Thus the cautious statement in A is correct.
