Answer to Question #314766 in Evolution for Sam

Question

Are two species closely related or distantly related if their DNA differs by 2 percent? Explain.

Answer 1

A DNA difference of 2% means that the two organisms have 98% similarity in DNA. These two organisms are closely related.

For instance, it is worth noting that individual humans generally differ by about 0.1 percent genetically, and about 2 percent from Chimpanzees. Therefore, humans are closely related to Chimpanzees
