the process of changing to suit environment
Answers
In behavioral ecology, an adaptive behavior is a behavior which contributes directly or indirectly to an individual's survival or reproductive success and is thus subject to the forces of natural selection.[1] Examples include favoring kin in altruistic behaviors, female selection of the most fit male, and defending a territory or harem from rivals.
Conversely, a non-adaptive behavior is a behavior or trait that is counterproductive to an individual's survival or reproductive success. These might include altruistic behaviors which do not favor kin, adoption of unrelated young, and being a subordinate in a dominance hierarchy.
Adaptations are commonly defined as evolved solutions to recurrent environmental problems of survival and reproduction.[2] Individual differences commonly arise through both heritable and nonheritable adaptive behavior. Both have been proven to be influential in the evolution of species adaptive behaviors, although heritable adaptation remains a controversial subject.[2]
