Probably better to imagine it as a strictly typed language and you're swapping in compatible components so it does compile. There's a vaguely understood second level here where it's not just first order changes mutating in and out, but second and third and fourth order change that enable an organism to evolve more easily in specific directions. edit: although some genetic mutations do of course result in organisms that will certainly die, possibly before being born
