If two species have similar chemical hereditary material what can it indicate about evolution?
Answer and explanation
Correct answer: They may have some level of common ancestry
The governing concept is molecular evidence for evolutionary relationship. Hereditary material stores biological information, and substantial similarities in its chemical composition or sequences can indicate that organisms inherited some information from a common ancestor. Such evidence does not prove that the organisms are the same species, nor does it eliminate variation or show that evolution has stopped. Therefore option A is the most accurate conclusion.
