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
