Final answer:
Primate skulls have evolved to emphasize vision over olfaction, featuring forward-facing eyes for stereoscopic vision, a large cerebrum for processing complex sensory information, and a reduced snout.
Step-by-step explanation:
With respect to the evolution of the sense organs, the primate skull is characterized by a variety of features. Primates, including humans, generally exhibit a reduced reliance on the sense of smell with a relatively small snout, and a larger emphasis on the sense of vision. Their eyes are usually large and forward-facing, providing an overlap of the visual fields of the two eyes which facilitates stereoscopic vision. This adaptation is paramount for depth perception and is accompanied by binocular vision, allowing primates to see a single three-dimensional image with both eyes. Furthermore, primates have relatively large brains and cerebrums which process complex sensory information and facilitate higher intellectual functions. These evolutionary traits have enabled primates to interact more effectively with their environment and to develop complex social behaviour's.
