Question

Quizplus · Accepted Answer

The encephalization quotient (EQ) is a measure of the increase in brain size relative to body size beyond what would be expected based on evolutionary scaling of body size. It takes into account both brain weight and body weight and is used to compare the relative brain sizes of different species. Therefore, B is the best choice for this question.
