Unformatted text preview: Test Two Pan troglodytes (chimpanzee) a. enviroment • Tropical Africa b. diet • principally frugivorous, though also eats leaves, insects, and occasionally hunts small mammals c. locomotion • arm swinging in trees • knuckle walking on the ground • occasional bipedalism d. morphology ( characteristics of all apes) • arms lower than legs • broad thorax • mobile wrist • “stiff back” ( few lumbar vertebrae) • absence of tail • dental formula 2,1,2,3/2,1,2,3 • Y-5 cusp pattern on lower molars e. behavior • use of tools ( termite probes) • hunts mammals • polygyny (you are a fag)- multiple make, multiple female troop structure • males remain in the troop in which they were born, while females emigrate from their birth troop • varied mating patterns, from promiscuity to short-tem pair bonding • highly social animals • often use as a model for early hominid evolution • culture? Gorilla Gorilla (gorilla) a. environment • tropical Africa b. diet • folivory (leaves, buds, pith) c. locomotion • knuckle walking on the ground d. morphology • arms longer than legs • broad thorax • mobile wrist • “stiff back” (few lumbar vertebrae • absence of tail • dental formula: 2,1,2,3/2,1,2,3 • Y-5 cusp pattern on lower molars • marked sexual dimorphism in body size, with makes two times larger than females • prominent sagittal crest e. behavior • polygny- single male and multiple female troop structure ( one adult male [ silverback male] and several adult females; offspring) • both males and females emigrate from their birth troop • not territorial • no evidence of tool use Pongo pygmaeus (orang-utan) a. environment • rainforest of Borneo and Sumatra (islands of Indonesia) b. diet • frugivory c. locomotion • arboreally adapted; slow, cautious climbing in trees d. morphology • arms longer than legs • broad thorax • mobile wrist • “stiff back” ( few lumbar vertebrae) • absence of tail • dental formula: 2,1,2,3/2.1.2.3 • Y-5 Cusp pattern on lower molars • marked sexual dimorphism in body size, with males two time larger than females • prominent sagittal crest e. behavior • adult male and female lead essentially solitary lifestyles, with the territory of a single male overlapping the territories of several females ( noyau social structure). social unit is adult female and her dependent offspring • use of tools (sticks are modified and use to open fruits and to probe for honey or termites) Hylobates lar (gibbon) a. environment • rainforest of Southeast Asia ( china, Thailand, Vietnam, Indonesia) b. diet • frugivory c. locomotion • brachiation (rapid arm-over-arm movement through the trees) d. morphology • arms longer than legs • broad thorax • mobile wrist • “stiff back” ( few lumbar vertebrae) • absence of tail • dental formula: 2,1,2,3/2,1,2,3 • Y-5 cusp pattern on lower molars • no sexual dimorphism in body size or canine size; males and females are equivalent in size e. behavior •...
