The Design of Life and the Golden Ratio

“All life is biology.
All biology is physiology.
All physiology is chemistry.
All chemistry is physics.
All physics is math.”

Dr. Stephen Marquardt.

The design of life is based on a “Golden Ruler™, a ruler composed of golden ratios within golden ratios. It has long been known that the Golden Section, (also Golden Ratio or Divine Proportion), appears in certain proportions of living organisms.  In 1997, I began to wonder how universal this was and how far it could be applied.  I took a golden section of a line not just once, but many times, to form what I like to call the “golden ruler,” shown as follows:

First, take a line and divide it so that the proportion of (B) to (A) is the same as the proportion of (C) to (B):

Sectioning a line to form the Golden Section, Golden Ratio or Divine Proportion based on Phi

Divide the line again and again in the same way:

Successive Golden Sections of a Line to show phi or golden ratio points

Combine the segments to create a measuring stick or “Golden Ruler™:”

This appears in the proportions of many life forms:

In the dimensions of the human body:


In the dimensions of the human face:


In the dimensions of spirals in sea shells:


In the dimensions of the body sections of insects:

In the dimensions of fins and other key body features in sea life:


The Golden Ruler™ can be expanded to a Golden Grid™

You can take the process another step further by creating a “Golden Grid,” taking it from one dimension to two dimensions:

This approach can be used to explain the physical proportions of many life forms, but the most beautiful application is found in humans:

It appears that this “golden ruler” is a common, if not universal, metric in the design of living organisms.

    thanx for the amazing info. i have already read about it in The Da Vinci Code by Dan Brown. Could you please include more geometrical charts from which we can derive phi?

  2. Gayatri says

    Could you provide a printable golden ratio grid like the one in the image above along with the one already in the DIY page?

    This is an excellent description of the divine design and I congratulate you for the explanation and the many drawings to explain the human body, the spirals of shell of a snail or the body of an insect. Wonderfully and beautifully explained. Prof. Plammoottil Cherian, M.Sc., Ph. D

    I read very briefly regarding the golden ratio, The Phi in the book The Da Vinci Code by Dan Brown and thrilled to note that he is the first man to measure the human body parts by physically measuring after exhuming the dead bodies. He also mentioned that the sun flower seed formation is following the golden ratio like the conical shell. If somebody throws some more light in this regard in addition to the above illustrations, is highly appreciated.
