Writing a book

Writing a book is not an evolutionary process?

I wonder if the process of book forming is the same as a species forming.

A book is an object evolved, but it is through the interaction of the writer

and the book itself. The writer also evolves through the book. What is

the key? The final resultant book or the writer who can write more books that

stimulate other writers.

I think the evolutionary suject is the writer and writing process assisted by

the evolving device, the book.
