What can be inferred from greater DNA similarity between organisms?
Answer and explanation
Correct answer: They may be more closely related evolutionarily
DNA stores hereditary information, so comparing DNA sequences helps reveal evolutionary relationships. When two organisms have greater similarity in their DNA, they are generally likely to have shared a more recent common ancestor than organisms with less similarity. However, similarity alone does not prove that they are the same species, and it does not mean that they lack variation. Therefore, option B is correct.
