Why can it be difficult to consider two similar-looking organisms as the same species using appearance alone?
Answer and explanation
Correct answer: Because reproductive ability and genetic relationship are also important
External appearance is useful for classification, but it may be misleading because unrelated organisms can evolve similar features and members of one species can show variation. Species identification also considers the ability to reproduce successfully and, where needed, genetic relationships and evolutionary history. Hence option A is the best answer. Options B, C and D are absolute or plainly incorrect statements about appearance, variation and species.
