Adaptation

In biology, an adaptation, also called an adaptive trait, is a trait with a current functional role in the life of an organism that is maintained and evolved by means of natural selection. Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation. Adaptations enhance 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.

General principles

Adaptation is, first of all, a process, rather than a part of a body. An internal parasite (such as a liver fluke) can illustrate the distinction: such a parasite may have a very simple bodily structure, but nevertheless the organism is highly adapted to its specific environment. From this we see that adaptation is not just a matter of visible traits: in such parasites critical adaptations take place in the life cycle, which is often quite complex. However, as a practical term, adaptation is often used for the product: those features of a species which result from the process. Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function is in doubt. By using the term adaptation for the evolutionary process, and adaptive trait for the bodily part or function (the product), the two senses of the word may be distinguished.

Literary adaptation

Literary adaptation is the adapting of a literary source (e.g. a novel, short story, poem) to another genre or medium, such as a film, stage play, or video game. It can also involve adapting the same literary work in the same genre or medium, just for different purposes, e.g. to work with a smaller cast, in a smaller venue (or on the road), or for a different demographic group (such as adapting a story for children). Sometimes the editing of these works without the approval of the author can lead to a court case.

It also appeals because it obviously works as a story; it has interesting characters, who say and do interesting things. This is particularly important when adapting to a dramatic work, e.g. film, stage play, teleplay, as dramatic writing is some of the most difficult. To get an original story to function well on all the necessary dimensions — concept, character, story, dialogue, and action — is an extremely rare event performed by a rare talent.

Perhaps most importantly, especially for producers of the screen and stage, an adapted work is more bankable; it represents considerably less risk to investors, and poses the possibilities of huge financial gains. This is because:

Adaptation (film)

Adaptation (stylized as Adaptation., with the period included) is a 2002 American comedy-drama metafilm directed by Spike Jonze and written by Charlie Kaufman. The film is based on Susan Orlean's non-fiction book The Orchid Thief, with numerous self-referential events added. The film stars Nicolas Cage as Charlie and Donald Kaufman, and Meryl Streep as Susan Orlean, Chris Cooper as John Laroche, with Cara Seymour, Brian Cox, Tilda Swinton, Ron Livingston and Maggie Gyllenhaal in supporting roles.

Though the film is billed as an adaptation of The Orchid Thief, its primary narrative focus is Charlie Kaufman's struggle to adapt The Orchid Thief into a film, while dramatizing the events of the book in parallel. Adaptation also adds a number of fictitious elements, including Kaufman's twin brother (also credited as a writer for the film) and a romance between Orlean and Laroche, and culminates in completely invented events including fictional versions of Orlean and Laroche three years after the events related in The Orchid Thief, Kaufman and his fictional twin brother.
