Untitled Document Reoriented Use of Senses Primates have certain senses that are more important than others. The shape of the face and skull in primates reflects the senses that are most important. It is important to realize that the shape of an animal is related to the activities of the animal.
All primates rely more on sight than any other sense.
As a result, primate skulls are shaped in a way to maximize their vision. The eyes of primates are located in the front of the face, rather than on the side of the head as they are in dogs or horses. Due to the forward position of the eyes, primates are capable of stereoscopic vision, and thus they have depth perception.
