The '''behavior''' of a [[system]] is what it does (contrast [[structure]]). It is the processes executed or supported by a system.
Behavior or behaviour (see [[American and British English spelling differences#-our,_-or|spelling differences]]) refers to the [[action (philosophy)|action]]s or [[reaction]]s of an [[organism]], usually in [[relation]] to the [[environment (biophysical)|environment]]. Behavior can be [[conscious]] or [[Unconscious mind|unconscious]], [[overt]] or [[covert]], and [[voluntary]] or involuntary. In animals, behavior is controlled by the [[endocrine system]] and the [[nervous system]]. The complexity of the behavior of an organism is related to the complexity of its nervous system. Generally, organisms with complex nervous systems have a greater capacity to learn new responses and thus adjust their behavior. [[Human behavior]] (and that of other [[organism]]s and mechanisms) can be common, unusual, acceptable, or [[deviant behavior|unacceptable]]. Humans evaluate the [[taboo|acceptability]] of behavior using [[social norm]]s and regulate behavior by means of [[social control]]. Animal behavior is studied in [[comparative psychology]], [[ethology]], [[behavioral ecology]] and [[sociobiology]].
[[Ronald J. Konopka]] and [[Seymour Benzer]] of [[Caltech]] were the first to establish the genetic basis of behavior, when they isolated three [[circadian rhythm]] mutants in [[Drosophila melanogaster]] which were later mapped to a single gene [[Period (gene)|Period]]<ref>[http://www.pnas.org/cgi/content/abstract/68/9/2112 Clock Mutants of Drosophila melanogaster - Konopka and Benzer 68 (9): 2112 - Proceedings of the National Academy of Sciences<!-- Bot generated title -->]</ref>, <ref>[http://www.hhmi.org/biointeractive/vlabs/transgenic_fly/content/clockexhibitframe.html HHMI Virtual Exhibit 2000<!-- Bot generated title -->]</ref>.
