Cards

Term
Goals of Classification
Definition
To look at evolutionary relationships
Term
Taxonomy Definition
Definition
The classification of things from broad to narrow based on shared charecteristics.
Term
Phylogeny
Definition
Evolutionary relationship b/w a group of organisms. The more shared the closer the relationship.
Term
Homologies
Definition
Similarities that we share because of a common ancestor.
Term
Homology examples
Definition
Term
Primitive homologies
Definition
Shared through remote ancestry
Term
Derived Homologies
Definition
Modified traits from ancestral/derived traits
Term
Analogies
Definition
Appear similar but do not share a common ancestor. Shares common need.
Term
Characteristics used to define primates
Definition
Generalized body structure, prehensile hands, brains, stereoscopic vision
Term
Primate distribution
Definition
Central/South America, Africa, Asia. Grasslands/savannahs/wooded areas.
Term
Prosimians
Definition
lemurs, lorises, tarsiers, etc. Most primitive, lack post orbital bar/plate, long noses w/ wet pad.
Term
Anthropoids
Definition
Include Platyrrhines and Catarrhines
Term
Catarrhines
Definition
Old World Anthropoids, narrow downward facing nostrils, 2.1.2.3. dental formula, lack prehensile tails
Term
Platyrrhines
Definition
New world monkeys, 2.1.3.3. dental formula, prehensile tails.
Term
Cercopithecoids
Definition
Old world monkeys, grasslands,
Term
Hominoids
Definition
Old world apes that brachiate, wooded environ., mostly multi-female and male social groups. Dominance order and cooperation.
Term
Why study primate behavior?
Definition
To collect information on free-ranging primates
Term
Ecology
Definition
Relationship between organisms and all aspects of environment (predators, vegetation, availability of food, types of food, water...)
Term
Socioecology
Definition
How socia structure is influenced by ecological conditions
Term
4 factors that influence social organization
Definition
1. Distribution of resources
2. Predation
3. Activity pattern
4. Dispersal
Term
Distribution of resources
Definition
Females mimic the distribution of resources; clumped vegetation clumped groups and terriorialism, scattered vegetation scattered groups)
Term
Distribution of resources
Definition
Females mimic the distribution of resources; clumped vegetation clumped groups and terriorialism, scattered vegetation scattered groups)
Term
Predation
Definition
More predators larger group
Term
Activity Pattern
Definition
Diurnal or nocturnal. Nocturnal are solitary, diurnal social because of predators.
Term
Philopatry
Definition
One stays in natal group
Term
Function of dispersal
Definition
Reduce inbreeding and competition
Term
What does estrus look like and what is its purpose
Definition
Pinkish swelling of genital area to indicate willingness to mate.
Term
Sociobiology
Definition
Study of biological basis of social behavior.
Term
Reproductive success
Definition
The success of carrying your genes through to the next generation and for that generation to reproduce.
Term
Intersexual selection
Definition
Females choose who she mates with
Term
Sperm competition
Definition
Sperm competition is a term used to refer to the competitive process between spermatozoa of two different males to fertilize an egg of a lone female.[1] Competition occurs whenever females engage in promiscuous mating to increase their chances in producing more viable offspring.[2] Sperm competition is an evolutionary pressure on males, and has led to the development of adaptations to increase males' chance of reproductive success
Term
Know the behavioral (physical and social attributes that are unique to and the degree to which we see these in primates
Definition
Increased parental investment, extended ontogeny, and longer lifespan.
Term
Ontogeny
Definition
More socially complex the longer in juvenile stage because there's more to learn.
Term
Kin selected
Definition
Evolutionary benefits of altruistic behavior to the kin group outweigh costs to individual acting altruistically. Will most strongly act this way when living with relatives.
Term
K- Selected Species
Definition
They are populations of a roughly constant size whose members have low reproductive rates. The offspring produced require extensive postnatal care until they have sufficiently matured. They are very limited in resourses therefore they are a very competitive species. Humans are examples of a k-selected species.
Term
R-Selected Species
Definition
They are populations that experience rapid growth of the J-curve variety. The offspring produced are numerous, mature quite rapidly, and require very little postnatal care. Consequently, this population grows fast, reproduces quickly, and dies quickly. Bacteria are examples of r- selected species.
Term
Food sharing
Definition
Altruistic trait because the primate is putting themselves in jeopardy
Term
Altruism
Definition
Reduces the reproductive success of the individual giving but improve for the recipient.
Term
Autonomic communication
Definition
physiological and not voluntary, raised body hair/odor
Term
Intentional communication
Definition
eyelid flash/yawn
Term
Lip flip submissiveness w/o yawn
Definition
submissiveness
Term
Facial expressions
Definition
All primates that live in groups express communication through facial expressions
Term
Relaxed stance
Definition
Neutral expression
Term
Very relaxed expression
Definition
neutral with drop lip
Term
Distress face
Definition
fear grin
Term
Displays
Definition
convey dominance or threat
Term
sexual dimorphism
Definition
multi-female/multi-male controlled by dominance hierarchy social structure
