Concept 51.6 The concept of inclusive fitness can account for most altruistic social behavior Most social behaviors are selfish, meaning that they benefit the individual at the expense of  others, especially competitors. Behavior that maximizes an individual’s survival and reproductive success is favored by  selection, regardless of its effect on other individuals. How do we account for behaviors that help others? Altruism  is defined as behavior that appears to decrease individual fitness but increases  the fitness of others. Belding’s ground squirrel lives in some mountainous regions of the western United States. The squirrel is vulnerable to predators such as coyotes and hawks. If a squirrel sees a predator approach, it often gives a high-pitched alarm call, which alerts  unaware individuals. The alerted squirrels then retreat to their burrows. This conspicuous alarm behavior calls attention to the caller, who has a greater risk of being  killed.  In honeybees, workers are sterile but labor on behalf of a single fertile queen. Workers will sacrifice themselves to sting intruders in defense of the hive.
