Primate Diversity Flashcards
Two primate taxonomies
ecological: prosimians and anthropides
phylogenetic: strepsirhines and haplorhines
Tarsier (taxonomies, location, 3 traits)
prosimian and haplorhine Asia huge eyes = nocturnal reduced size/complexity of nasal cavity loss of rhinarium
Strepsirrhini (location, 2 traits)
Africa, Asia, Madagascar
grooming claw
tooth comb
Lemuriforms location
Madagascar (only monkey in Madagascar)
Lorisiformes (two families and their location)
Galagidae - Africa
Lorisidae - Africa and Asia
aye-aye: scientific name and dental formula (why is this special?)
Dabentoniidae
1.0.1.3/1.0.0.3
it’s an autapomorphy
Antropoidea (7 traits)
fused frontal bone fused mandibular symphysis (jaw) larger brains postorbital closure (bar+plate) increased reliance on vision diurnal lack tapetum lucidum (shiny thing in cat eyes)
Different orbital closures
bar only - strepsirrhine
partial plate - tarsier
complete plate - anthropoidea
Platyrrhini location
new world (NWM)
catarrhini (superfamily)
cercopithecoidea (NWM) - Africa and Asia
Difference between OWM and NWM (names and 2 traits each)
OWM - Ceropithecoidea = ear tube & 2 premolars
NMW - platyrrhines = no ear tube & 3 premolars
Difference between Colobinae and Cercopithecinae (3 traits each)
Colobinae - high teeth cusps, eat leaves, complex stomach
Cercopithecinae - low teeth cusps, eat fruit, cheek pouches
Hominoidea location and common names
Africa and Asia
Apes and humans
Difference between cercopithecoids and hominoids (2 traits, 4 traits)
cercopithecoids - bilophodont molars (two lumps) and have tails
hominoids - simple molars, no tails, larger brain, Y-5 molar pattern
Aotinae special trait
only nocturnal platyrrhini and and anthropoid
