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. In asexual reproduction mostly identical clones are created.Adaptation arises in asexual p… Adaptation (biology) A characteristic of an organism that makes it fit for its environment or for its particular way of life. Firstly, it is the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness.

Content provided and moderated by BiologyOnline Editors.Adaptation, in biology and ecology, refers to the process or trait through which organisms or the populations in a habitat become more suited or a better fit to their environment. Views expressed here do not necessarily reflect those of Biology Online, its staff, or its partners. All offspring, whether formed sexually or asexually, inherit their traits from their parents. It may also pertain to the trait that made the species a better fit to the environment. The act or process of adapting. An adaptation, or adaptive trait, is a feature produced by DNA or the interaction of the epigenome with the environment.

It is not intended to provide medical, legal, or any other professional advice. Adaptation is the root concept that grew into Darwin's theory of natural selection. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics. The state of being adapted.

A biological adaptation is an anatomical structure, physiological process or behavioral trait of an organism that has evolved over a period of time by the process of natural selection such that it increases the expected long-term reproductive success of the organism.The term adaptation is also sometimes used as a synonym for natural selection, but most biologists discourage this usage.
