Perfection in nature is a bugaboo. We have an idealized concept of a "perfect" sunflower and every example in nature fails to conform to our preconceived notion. If I took a thousand pictures of different sunflowers, would I find one closer to the ideal than this one? Perhaps we put too much stock in idealized perfection and need to look more at usefully adequate perfection? There are some things that can be perfected and we can do things perfectly, but the abstract concept of natural perfection may never be obtained, at least in this world.
