colobines

subfamily of OWM that have evolved anatomical specializatoin:in their teeth and in a large sacculated stomach for consuming a diet of leaves, including African colobus and Asian langurs

primates considered generalized

they have retained ancestral mammalian trait

statements accurate describing a chimpanzees

they occasionally hunt and eat young monkeys

stereoscopic vision

this is interpreted by the brain and results in the perception of depth or (3-D).

hemisphere

two halves of the cerebrum connected by mass fibers

binocular vision

vision characterized by overlapping visual fields provided by forward-facing eyes. and is essential to depth perception.

Gibbons and Siamangs

Omnivory

Having a diet consisting of many kinds of food including plants, meat, and insects.

New World monkeys and Old World monkeys have been geographically separated for a minimum of 30 million years, yet they are clearly recognizable as monkeys. This is an example of the evolutionary principle of
