For those who do not know what the golden ratio is: it is a number represented with the Greek letter phi, which had a special importance to the Greeks. It is equal to (1 + sqrt(5))/2 and appears in pentagons, dodecahedrons, and many other shapes.

I have read a few articles about the golden ration appearing in nature and in the ideal proportions for humans. Ratios such as the length of your elbow to the middle finger tip to that of your forearm is almost exactly the golden ration. Also the ratio of each spiral of a conch shell, etc. Do you believe this is purely by coincidence or is this a natural phenomenon, similar to the constant appearance of e or pi?
