What do vestigial organs suggest about evolution?
Answer and explanation
Correct answer: They may be remnants of organs useful in ancestors
Vestigial organs are reduced structures that have little or no important function in an organism today but may have performed a useful role in its ancestors. Their presence can reveal inheritance from an earlier body plan and therefore supports evolutionary descent. Option A is correct. They are not necessarily newly formed, they contain genetic information like other body structures, and their existence is not simply caused by disease.
