ANT 251 Lecture Notes - Lecture 16: Tapetum Lucidum, Mandibular Symphysis, Dentition
Document Summary
11:46 am: differences from strepsirhines, evolved later in time, more derived characteristics, more suited to diurnal life, larger brain and body size, reduced reliance on smell, greater degree of color vision, classification, order: primates, suborder: haplorhines. Infraorder: tarsiers, catarrhines (old world monkeys + hominoids, platyrrhines (new world monkeys, characteristics, anatomical, derived, postorbital closure, no tapetum lucidum. Fused frontal bone/fused mandibular symphysis: ancestral, non-bicornuate uterus, dental formula varied, no tooth comb, other shared. Increased parental care: mutual grooming, complex social structure, monkeys, majority of primate species, nwm and owm. Separated by geography for 30 million years: owm and hominoids weren"t so they"re more related. Sexual dimorphism: physical diff btw males and females. Several types of social organization: multi-male, only female, male and female groups, Infraorder: platyrrhines polygamous: wide range of size, diet, adaptation (12 oz - 20 lbs, characteristics, anatomical, broad nose, outwards facing nostrils, 2-1-3-3 dental formula (ancestral, ring like ear structure, not ear tube, other, diurnal (exc owl monkey)
