Primate Behaviour Flashcards
Louis Leakey
found stone tools and the earliest human ancestor fossils in east africa
recruited the “trimates” to study wild primate behaviour
who were the trimates
jane goodall
diane Fossey
Birute Galdikas
Jane Goodall
studied chimps beginning in the 1960s
diane fossey
studied gorillas beginning in 1966
Birute Galdikas
studied orangutans beginning in 1971
what monkeys did anne zeller work with
macaques
anne zellers work
recognizing that primates have emotions- the same emotions as humans
facial gesture, deception, grief, infant socialization, object use, art
when captive primates are given paint…
many of them will paint art similar to young preverbal humans
anne zeller recognized that _________ are important to primates and __________ between then
facial gestures
interpreted
macaques use objects to make noise for..
entertainment and to dominate
primates are models for
hominoid behaviour
non human primates provide the only living model for early humans and their ancestors
types of monkey models
experimental- controlling specific variables in an artificial environment
natural observation in wild- better but $$ and time consuming
darwin was not the first to study primates, but he was the first to
link them to humans
he recognized similarities between animal and human facial expressions
how did darwin compare primates to humans
went from examining structure to behavioural comparisons
behavioural ecology
what we’re looking at when studying primates in their natural environment
8 things were looking at when studying primates in their natural environment
quantitiy and quality of food distribution of food resources dustribution of water distribution and types of predators distribution of sleeping sites activity patterns relationship with non predator species impact of human activities
distribution of food resources
how widely do they have to travel to be fed- has implications in pre agricultural humans
distribution and types of predators
is it every man for themselves? do they protect eachother? would they die for eachother?
distribution of sleeping sites
do they have a home base?
primate society structure
all ranked societies with some individuals having more dominance than others
more complex primates means
more complex dominance systems
dominance is expressed through
grooming, birth status, fighting, submission
grooming
submissive animal will offer to groom a more dominant animal, if the dominant one agrees thats the beginning of a relationship
grooming is important in
courting and mother and infant bonds
birth status
infants born to higher status females will be born at a higher level in the dominance hierarchy
can also climb the ranks but thats much harder
