All biologists agree that organismal traits commonly reflect adaptations. However, much disagreement has arisen over the role of history and constraint in the appearance of traits as well as the best methodology for showing that a trait is truly an adaptation. A trait may be a function of history rather than adaptation.
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.

Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization. Behavioural adaptations are inherited systems of behaviour, whether inherited in detail as instincts , or as a neuropsychological capacity for learning .
Adaptations can take many forms: a behavior that allows better evasion of predators, a protein that functions better at body temperature, or an anatomical feature that allows the organism to access a valuable new resource — all of these might be adaptations. Many of the things that impress us most in nature are thought to be adaptations.
