Question

Quizplus · Accepted Answer

The unity among living organisms can be explained through the theory of evolution, which suggests that all living organisms share a common ancestor. This common ancestry means that all organisms share certain characteristics, such as the use of DNA as genetic material and the presence of cells. Therefore, the best answer is D, as the common ancestry provides the best explanation for the unity among living organisms. Option A is incorrect because not all organisms are multicellular, and option B is incorrect because not all organisms are producers. Option C is incorrect because living organisms have evolved and changed over time.
