Human Body

As the Nautilus shell example demonstrates, peculiar mathematical relationships are exhibited in many of nature’s growth cycles. The human body demonstrates many of the same golden proportion relationships, as well. Each tooth is related to each other based on type. For example, the width of the central incisor is in the golden proportion to the width of the lateral incisor. The lateral incisor is in the same golden proportion to the canine, and the canine is in the golden proportion to the first premolar.

It is commonly known that the human hand possesses many golden proportions. Specifically, the individual bones in the index finger are related to each other by Phi. Starting with the tip of the finger to the base of the wrist, each section is larger than the preceding by approximately 1.618.
