What is the importance of a vestigial organ in the study of evolution?
Answer and explanation
Correct answer: It can indicate an organ that was useful in ancestors
A vestigial organ is a reduced structure whose original function has become greatly reduced or absent in the present organism. Comparative anatomy suggests that such a structure may have performed an important function in an ancestor. It therefore provides evidence about ancestry and evolutionary change, although it does not by itself explain every detail of evolution. It is not necessarily newly formed, gene-free, or limited to plants, so option A is correct.
