Primates 1 Flashcards
are chimpanzees humans common ancestor
no but we share a common ancestor
what 3 social behaviours do we share with primates
- warfare
- culture and tradition
- prosocial behaviour
why do rates of evolution differ
depending on how intense of selective pressures
what is the order of classification heirachry levels
Kingdom: > Phylum: > Class: > Order: > Suborder: > Infraorder: > Superfamily: > Family: > Subfamily: > Genus: > Species:
what are the three major primate groups
Prosimii, Tarsiodea, Anthropoidea
what doe the distributions of living and extinct non human primates show
- Moved less tropical
- Have occupied every continent besides Australia
diff. b/w ancestral and derived traits
- Ancestral: retained from ancestral groups
- Derived: newly arising in focal taxonomy (not all share)
name several points that make a primate
- prehensile hands feet stereoscopic vision olfactory reduction large brain prolonged dependency of young
what d the primate traits relate to in terms of purpose
arboreal lifestyle
explain humans binocular vision
fields of vision of the 2 eyes overlap so same image is perceived (front eyes)
explain stereoscopic vision
o Enables distance: survive in arboreal
o Eye sends signal of visual image to both hemispheres to create an image of depth
do all primates have colour vision
only diurnal
why do primates have generalised dentition
for meat, fruits, all types)
what can teeth tell us
– dietary preferences
– age of individuals and developmental patterns
– phylogenetic relationships
– social structure
whats a reason for large brains in primates
highly social: need to remember relationships + past events + social concepts + where food is (navigate environment) + avoid predators
