cost benefit analysis animals appear to weigh the costs and benefits of responding to a
particular situation in various ways
foraging when animals seek food
piloting use of familiar landmarks
compass orientation movement oriented in a specific direction
true navigation ability to locate a specific place on earth's surface
circadian clock maintains a 24-hour rhythm of chemical activity-animals use sun for
direction
, communication process in which a signal from one individual modifies the behavior of
another individual
altruism behavior that has a fitness cost to the individual exhibiting it and a fitness benefit
to the recipient, appears to contradict this pattern (queen bees giving themselves up for the queen
to reproduce)
hamilton's rule can be expressed as Br>C, where B is the fitness benefit to the
beneficiary, r is the coefficient of relatedness, and c is the fitness cost to the actor
inclusive fitness the combination of direct and indirect fitness components
kin selection natural selection that acts through benefits to relatives and results in
increased indirect fitness
eusoiaity sometimes altruistic behavior is involuntary; in bee population, workers
sacrifice most/all of their direct reproduction to help rear the queen's offspring
