Physically, a human being is more like musical expression than a set of construction blueprints. The human body has near-perfect symmetry and economies of expression through fractal geometry that are quite evident in the structure of the circulatory system, for example, or the nervous system. Just look at a drawing of veins and arteries and you'll notice the fractal patterns of geometry -- the same patterns you'll see drawn in the underside of a leaf, by the way.

The same is also true with human hair and skin cells. Every police detective knows that the human fingerprint is made up of readily identifiable patterns that are connected through a sort of biological artistry. In any human fingerprint, you'll notice the loops, swishes and curves that give strong clues to the underlying fractal geometry. Fingerprints aren't built with cellular bricks, they're built with repeating patterns that give us strong clues about the true structure of our DNA.
