Question

Quizplus · Accepted Answer

While bipedalism is a characteristic of some primates, it is not universal among all members of the order. Specialized teeth and a strong sense of smell are also not defining characteristics of primates. However, the increased dependence on complex behavior, learning, and behavioral flexibility is a key trait distinguishing primates from other animals.
