All works of literature are the results of an evolutionary process. They have been influenced by many works that came before, selected for through publication, and generated new elements that make them unique and successful. There is also an evolutionary process at work within the book itself. The story develops over the course of the narrative, drawing on past influences, selecting for elements that move the story along, and generating an ending that is indicative of this particular evolutionary journey. Where the end product of a biological evolutionary process is the creation of a new species, the end product of a novel is literally its ending scene, words that must resolve, or not, the preceding action of the story, incorporating the evolution of the plot, characters, and themes throughout. On a larger scale an adapted literary work is the end product of an evolutionary process inspired by a generative original. On both theses levels it is helpful to analyze the results of the evolutionary processes, the ending of a story and the adaptation of an original work, in order to understand the process itself.
