Quizplus · Accepted Answer

The social brain hypothesis proposes that the neocortex ratio in humans gives them the cognitive capacity to maintain relationships with approximately 150 individuals, which is known as Dunbar's number. Therefore, option B is the correct answer. Option A is incorrect because the social brain hypothesis posits that brain size is related to group size, not diet. Option C is incorrect because there is no evidence to support this claim. Option D is also incorrect because brain size does not necessarily correlate with an affinity for larger groups. Option E is also incorrect because the social brain hypothesis is based on the idea that living in larger social groups led to the evolution of a larger neocortex ratio, not the other way around.
