ANT101H5 Lecture Notes - Lecture 9: New World Monkey, Rhinarium, Dentition
Document Summary
Leaping and clinging: haplorhini (tarsiers, monkeys, apes & humans) Bony plate at back of eye orbit. Unique features: anthropoidea (all monkeys, apes and humans) Wide range of size, diet, ecological adaptation. Broad flaring noses with outward nostrils (platyrrhine = flat nose) Long prehensile tails (tails have grasping ability) 3 pms: catarrhini (old world monkey, apes, humans) True brachiators: swings through tree with arms. Territorial: alarm calls: hominidae (greater apes and humans) 3 subfamilies: ponginae (asian great ape) indonesia - orangutan. Frugivorous - eats primarily fruit, so have to disperse for diet. Largely solitary - dispersed: gorillinae (gorillas) Large sexual dimorphism (difference in size between males and females in a species) Has a single dominant male in the troop. Shy, gentle vegetarians: homininae (chimpanzees, bonobos & humans) Complex social behaviour: hominini (humans and our ancestors) General primate social behaviour: social groups, dominance, grooming, reproduction, mother-infant relationships. Most primate societies are organized into dominance hierarchies.
