Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.
All adaptations help organisms survive in their ecological niches. The adaptive traits may be structural, behavioural or physiological. Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization.

Las adaptaciones pueden tomar muchas formas: un comportamiento que permite evadirse mejor de los depredadores, una proteína que funciona mejor a la temperatura corporal o un rasgo anatómico que permite al organismo acceder a un nuevo recurso valioso — todo esto podrían ser adaptaciones.
Una adaptación biológica es un proceso fisiológico, rasgo morfológico o modo de comportamiento de un organismo que ha evolucionado en el tiempo mediante la selección natural de tal manera que incrementa sus expectativas a largo plazo para reproducirse con éxito. Tiene tres significados, uno fisiológico y dos evolutivos: 1 .
An adaptation is a feature that arose and was favored by natural selection for its current function. Adaptations help an organism survive and/or reproduce in its current environment.
