Learn how organisms become fitted to their environment through natural selection and genetic variation. Explore examples of adaptation in structure, physiology, behavior, and evolution, and the challenges of identifying and testing adaptations.
19 de oct. de 2023 · In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Although scientists discussed adaptation prior to the 1800s, it was not until then that Charles Darwin and Alfred Russel Wallace developed the theory of natural selection.
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.

En biología evolutiva, la adaptación se refiere tanto a las características que incrementan la supervivencia o el éxito reproductivo de un organismo, como al proceso por el cual se adaptan los organismos: 1 . Adaptación como patrón: Cualquier carácter, morfológico, fisiológico, de conducta, o de desarrollo que incrementa la ...
