Human Brain & The Golden Ratio

By Suhail Jalbout

I always wondered whether the human brain played a role in the evolution of modern man. This may sound strange, none-the-less I wish to share my hypothesis with you. The prime objective of the hypothesis is to provide a new possible solution to the conventional medical methods that are used to treat the incurable hereditary diseases or genetic disorders.

Sight is one of the principal means of interpreting the world around us. Its instruments are the eyes. Vision results from the simulation of nerve cells in the retina, signaling patterns of light intensity and color. These signals are “decoded” by the brain to give perception of separate and different objects. The perception is the ability to convert continuous patterns of energy at the receptors into individual objects and events in space and time. The amazing phenomenon is that this process is performed from the same kind of electrical pulses running along the nerve fibers.

When a person views different objects in the field of his vision, the brain almost instantaneously gives the actual size of each object according to the distance between the objects and the viewer. This means the brain analyze, calculate, and possibly apply multiplying factors to the data that it receives without our awareness. We do not realize or think about the complex process that the brain undertakes to present the real picture to us. Since the brain takes the responsibility of analyzing the data it receives, is it possible that it performs other type of calculations that we do not know about?

Let us assume that a person is looking at a picture frame whereby its height is (H) and its width is (W). When the brain receives the data, it is possible that it performs manipulations to the dimensions of the frame. It may compare the ratio of the height to the width and vice versa. Its analysis will give the following ratios:

  • H/W = X where X > 1 (represents a rectangular shape)
  • W/H = Y where Y < 1 (represents a rectangular shape)
  • H/W = W/H = 1 (represents a square shape); a special case
Thus, the brain has two variables (X and Y where X > Y) and one constant (1) to manipulate. All the possible simple mathematical combinations that the brain can find between the 3 figures are:

  • XY = 1
  • X – Y = 1
  • X/Y = 1 + X
  • X/Y = 1 – X
  • X/Y = X – 1
  • X/Y = 1 + Y
  • X/Y = 1 – Y
  • X/Y = Y – 1
The brain can then proceed to calculate the values of X and Y by substituting (XY = 1) or (Y = 1/X) in the other 7 combinations. The substitution gives three different types of solutions:


Substituting (Y = 1/X) in the above 4, 5, 7, and 8 combinations gives the following impossible equations because X > 1 and X is positive:

4. X2 + X = 1

5. X2 – X = - 1

7. X3 – X = - 1

8. X3 + X = 1


Substituting (Y = 1/X) in combination 6 gives the following equation:

6. X3 – X – 1 = 0

Where X = 1.324718 (plastic number) and Y = 0.754877


Substituting (Y = 1/X) in combination 2 and 3 gives the following equations:

2. X2 – X – 1 = 0

3. X2 – X – 1 = 0

Where X = 1.618033 (golden ratio) and Y = 0.618034

The silver ratio or the plastic number was named by Dom Hans Van der Laan in 1928. It does not occur frequently in nature and is used occasionally in architecture designs. However, the golden ratio existed in nature since millions of years. It was discovered by the ancient Egyptians and was used in their construction. Almost everything in nature follows the golden ratio patterns which are more appealing to the human eyes. For example:

  • Pinecones has 5 spirals in one direction and 8 in the other or 8/5 = 1.60
  • Pineapples has 8 spirals in one direction and 13 in the other or 13/8 = 1.625
  • Sunflower opposing spirals come in the following ratios: 55/34 = 1.617, 89/55 = 1.618 and 144/89 = 1.617.
  • Petals of the different flowers follow the golden ratio such as: buttercup has 5, delphinium has 8, ragwort has 13, aster has 21, and plantain has 34.
  • The process of growing the plants follows the golden ratio. Also, the spacing of leaves around each branch spirals with respect to the golden ratio.
In addition, the golden ratio was discovered in snail shells, nautilus shells, starfish, sea urchins, dolphins, honey bees, DNA molecules, quantum world, spiral galaxies, and recently in the topology of space-time affecting the entire universe.

The human brain is continuously exposed to the golden ratio in nature. It analyses the ratio of different parts of living forms and concludes that the golden ratio gives the most beautiful construction that can exist. Consequently, there is no doubt that the brain will select the 1.618033 ratio instead of the 1.234718 ratio for the perfect shapes. Since scale and proportion are the key concept of the visual representation, the brain will thrive to apply the golden ratio to the human body. Its objective is to have optimal shaped bodies so that they appeal and attract the opposite human sexes one to the other. By doing so, males and females will reproduce and thus the brain will guarantee its continued existence.

Eric Kandel, the 2000 Nobel Prize winner for Medicine, discovered that the learning process causes signals to be transmitted into the DNA of nerve cells. Those signals can turn certain genes ON and other genes OFF. He also showed that not only our brains change (Neuroplasticity) but also we can change the genes that we inherited. Based on this extraordinary research, I believe that the brain had an important role in the evolution of modern man. Most probably it sends electrical patterns of biochemical origin to our genes to modify or change certain aspects of the human body during the process of evolution. Even though there are many theories about the following examples, I think that they may have occurred as a result of the communication between the brain and the genes:

  • The reason why modern man lost most of the hair that used to cover the body of his ancestors is because the brain realized that man changed his life style.
  • The reason why modern man has a redundant appendix is because the brain realized that man changed his diet.
  • The reason why the human embryo loses its tail when it develops into a fetus is because the brain realized that man became erect.
  • The reason why the present young human generation is losing their wisdom teeth is because the brain realized that man changed his diet.
Based on the above, it is quite possible that the brain communicated with the genes to develop the golden ratio in the human body during the process of evolution. As a result, the body of modern man is made up of building blocks whose proportional ratios are equal to the golden ratio. For example:

  • [first two finger segments] to [the full finger]
  • [elbow to fingertip] to [elbow to wrist]
  • [shoulder to fingertip] to [elbow to fingertip]
  • [hip to floor] to [knee to floor]
  • [shoulder line to top of head] to [head length]
  • [navel to top of head] to [shoulder line to top of head]
In order for the brain to communicate with the genes, addressable communication is necessary. Consequently, the brain transmits addressable electrical signals to the cells that contain the desired addressable genes. The transmission of data between the brain and the genes could be either locally, by pulses of electrical currents, or remotely, by pulses of electromagnetic fields, or by both.

The blood vessels are located throughout the human body. They form a complex network that enables the blood to reach every cell in the body. In addition, the blood has a high concentration of salt and water which makes it a good conductor for the flow of electric currents. So, it is quite possible that the addressable electrical signals (currents) from the brain are transmitted through the bloodstream conductor. These currents can reach any cell in the body but will only address the desired genes.

Alternatively, we know that electrical currents produce electromagnetic fields. When the brain transmits addressable electrical signals (currents) to address specific genes, they produce addressable electromagnetic fields. These electromagnetic fields can reach any cell in the body but will only address the desired genes.

In conclusion, it will be extremely interesting if scientists research and discover the addresses by which the brain communicates with the genes. The application will be very beneficial to the human race. Almost all the incurable hereditary diseases that are due to genetic disorder can then be treated and cured. Few of these diseases are: cancer, diabetes, Alzheimer, high blood pressure, heart diseases, anemia, cystic fibrosis, etc.


Following is an example of how the brain can modulate DNA to push for evolution:

Very recently, there was a shift in elephant’s population in Africa. Due to elephant’s poaching pressure, most elephants are now born without tusks. Normally, only 2% to 6% of African elephants are born tuskless. Now the rate has increased substantially, a trait that has evolved rapidly in the last century. In Addo Elephant National Park in South Africa, 98% of the 174 female elephants being born without tusks, In Gorongosa National Park in Central Mozambique, about 35% of the females are born tuskless. A large percentage of new born female elephants without tusks has been seen in Uganda, Zambia, and Tanzania.

The elephants are intelligent animals with fantastic memory. They must have realized that their tusks became a liability. To save the lives of their future generations, their brains must have communicated with their genes to switch OFF those responsible for creating their tusks. In addition, the elephants must have reasoned that all the new born females should be tuskless because they are the producers of new generations. Males need their tusks to defend their herd. Even if only few males survive hunters, they can still mate with all the females of the herd since they are polygynous. Most probably this is the reason why more females are born tuskless than males.
