ANTH 1 Lecture Notes - Lecture 4: Ape, Standard Anatomical Position, Hominidae
Document Summary
Strepsirrhini: lorises, lemurs, bush babies: most primitive of the primates, wet nose primates, more reliance on olfaction, lemurs and lorises. Grooming is an important part of social primates" lives. Tarsiers and all other dry nosed primates. Haplorhines: no tooth comb, no plate separating orbits from temporal fossa. Increased reliance on vision and greater degree of color vision. Difference between old world and new world monkeys. Old world: downward facing nostrils, 2 premolars, 2-1-3-3, no prehensile tail, can"t grab. New world: sideways facing nostrils, 3 premolars, 2-1-2-3, prehensile tail. Hominoidea (superfamiliy): all apes (great apes and lesser apes) Apes have y5 cusp pattern on lower first molars. Humans have 5 cusps on their molars. Anatomical position is standing up straight and palms out. Upper jaw (maximilla: i^(1,2), c^1, p^(3,4), m^(1,2,3, specify left or right. Occlusal: side that chews food, has cusps. Lingual: surface of tooth facing your tongue (inside side) Buccal: side that faces your cheeks (premolars, molars)
