An adaptation in biology is a trait with a current functional role in the life history of an organism that is maintained and evolved by means of natural selection. An adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation. Adaptations contribute to the fitness and survival of individuals. Organisms face a succession of environmental challenges as they grow and develop and are equipped with an adaptive plasticity as the phenotype of traits develop in response to the imposed conditions. The developmental norm of reaction for any given trait is essential to the correction of adaptation as it affords a kind of biological insurance or resilience to varying environments.

Famous quotes containing the word adaptation:
“In youth the human body drew me and was the object of my secret and natural dreams. But body after body has taken away from me that sensual phosphorescence which my youth delighted in. Within me is no disturbing interplay now, but only the steady currents of adaptation and of sympathy.”
—Haniel Long (18881956)
“The real security of Christianity is to be found in its benevolent morality, in its exquisite adaptation to the human heart, in the facility with which its scheme accommodates itself to the capacity of every human intellect, in the consolation which it bears to the house of mourning, in the light with which it brightens the great mystery of the grave.”
—Thomas Babington Macaulay (18001859)
“Whatever there be of progress in life comes not through adaptation but through daring, through obeying the blind urge.”
