ANT E101 Lecture Notes - Lecture 14: Frugivore, Lemur, Lorisoidea
Document Summary
Primates have retained a generalized postcranial anatomy. Retained five digits on hands and feet, allows them to better grasp things like tree branches as well as animals/insects they feed on. Retained two separate bones in the forearms, allows for mobility in that environment. Carnivores: high pointed cusps for tearing meat. Elephants: broad flat surfaces on cheek teeth for chewing tough grasses and plant materials. Primates: low, rounded cusps: generalized dentition to process the most types of food. Teeth in the upper and lower jaw. Heterodont dentition (incisors, canines, premolars, and molars) Insectivory: sharp crests for puncturing the outer skeleton of insects. Frugivory: low cups for crushing soft fruits. Folivory: well-developed shearing crests for cutting tough leafy material into small pieces. Madagascar, central and southern mainland africa, and se asia. Grooming claw on the 2nd digit of hind limb. Varied diets (fruits, flowers, leaves, gums, insects, small mammals, birds) Males and females do not live in large social groups.
