- Anthropocentrism
- attitude that regards humans as the central element of the universe
- Anthropomorphism
- attitude that attributes human behavior to inanimate objects/ natural phenomena
- Operational Sex Ratio
- F:M ratio, males need to compete for limite # of females.
- Human Mate Choice
- facial symmetry, high estrogen/testosterone levels
- MHC gene
-
females attracted to males w/ different MHC proteins
advantageous-> effective against different viruses - Monogamy
- both parents working together: imp when food is scarce-> female can't find food -> young die -> DNA not passed on
- Fixed Action Patterns
- behavioral traits that are embedded in genetic programs of biological organisms: sign stimuli, drive, motor program, programmed learning
- Sign Stimuli
-
initiates FAP
-physical/morphological
-chemical
-auditory
-behavioral - Drive
- triggered by genetic and environmental factors (sockeye salmon)
- Motor Program
- early steps in behavior leads to sequence of steps that follow until action is complete
- Programmed Learning
- (imprinting) genetically controlled. (golden eyed duckling)
- Proximate Causation
- behavior based on trigger stimuli and internal mechanisms
- Ultimate Causation
- behavior based on evolution- favored by natural selection
- in order for DNA changes, erors must occur in this process
- Replication
- greatest ability to produce variation resulting in very rapid reproduction exists in these cells
- bacterial (prokaryotic)
- Bonobo sexual behavior
- leisure/recreation -> females couldn't get food, drought, ate food on ground: bonding, reduced male agression
- chimp sexual behavior
- violent/infantcide: mate w/ every male to prevent infantcide, don't know if killing own child, permiscuous
