ANTHR 101 Lecture Notes - Lecture 9: Cercopithecinae, Colobinae, Frugivore
Document Summary
Greater body size, more variable body size. Larger degree of sexual dimorphism (in color and size) Ischial callosities (ishial bones are in pelvis and pointy in) calluses. Non-prehensile tails or almost no tail (tail used for balance) Nose faces down/palate usually more elongated (muzzle) Bilophodont molars (like two parts put together, pinched-in in the on butt to help sit on bad terrain middle, almost a figure 8) Cheek pouches to store food over a short time. Increased brain size, increased complexity of social behavior, and larger. Have suspensory, rotating shoulder that allows for wider shoulder rotation. Highly arboreal existence, with specialization of brachiating. Possess long arms and fingers, shortened thumbs and legs. Most are mainly frugivorous and thus can exert a lot of energy swinging through trees. Locomotion is a form of quadrupedalism known as knuckle-walking. Largely solitary living on sumatra and borneo. Males are twice the size and weight of the females.
