, behavior
the coordinated responses of whole living organisms to internal and/or external stimuli

own experience
cultural transmission
a transmission system in which animals learn through various forms of social learning
conceptual approach
integrating formerly disparate and unconnected ideas and combining them in new, cohesive
ways.
kin selection
demonstrates that natural selection not only favors behaviors that increase the reproductive
success of individuals expressing that behavior, but also favors the reproductive success of
those individual's close genetic kin
direct fitness
measured by the total number of viable offspring produced plus any effects indivdual 1 might
have on direct descendents of its own offspring
indirect fitness
measured by the increased reproductive success of individual 1's genetic relatives
inclusive fitness
sum of the direct and indirect fitness
theoretical approach
