What does greater similarity in genetic material of two organisms indicate?
Answer and explanation
Correct answer: Their evolutionary relationship may be close
The governing concept is comparative evidence in evolution. Genetic material stores inherited information, and organisms with more similar DNA sequences often share a more recent common ancestor than organisms with greater genetic differences. This similarity supports an inference of a closer evolutionary relationship, although scientists consider multiple kinds of evidence and do not treat it as proof that the organisms are identical. Therefore A is correct; B, C, and D contradict basic genetics.
