Nature has been using the "Golden Ratio" to design things pleasing to the eye, and to function their best for aeons. ie: As mentioned, the Nautilus shell, what we consider the most beautiful faces, the human hand's bone structure, your ear's cochlea, the DNA helix, flowers, etc.(http://cuip.uchicago.edu/~dlnarain/golden/activity7.htm)
