Question

Quizplus · Accepted Answer

The closer two organisms are on the "Tree of Life," the more genetically similar they are. This is because they share a more recent common ancestor and have had less time to accumulate genetic differences through evolution. Therefore, option D is the correct answer. Option A is incorrect because organisms that are genetically very different are likely to be on very different branches of the tree. Option B is also incorrect because while some closely related organisms may look similar, many others do not. Option C is incorrect because no two organisms (except for identical twins) are genetically identical.
