Good grief! Take your favorite OSS project, or even Windows. What do you think it would look like after 4 billion years of cut and paste.

Evolution is not directed by an intelligence. And moreover there is evidence that useless code in an evolutionary process can sometimes give you better results by protecting functional code against harmful mutations/crossovers.
