The Golden Section, also known as Phi, is manifested in
the structure of the human body. If the length of the hand
has the value of 1, for instance, then the combined length
of hand + forearm has the approximate value of Phi. Similarly the proportion of upper arm to hand + forearm is in the same ratio of 1: Phi .
The human face abounds with examples of the Golden Section. The head forms a golden
rectangle with the eyes
at its midpoint.The mouth and nose are
each placed at
golden sections of the distance between the
eyes and the
bottom of the chin.Phi defines the dimensions of the human profile.
Even when viewed from the side, the human
head illustrates
the Golden Proportion.

The first golden section (blue) from the front of the head defines
the position of the ear opening. The successive golden
sections define the neck (yellow),
the back of the eye (green) and the
front of the eye and back of the nose and mouth (magenta). The dimensions of the
face from top to bottom also exhibit the Golden Proportion, in
the positions of the eye brow (blue), nose (yellow) and mouth (green and magenta).

The human body is based on Phi and the number 5.The number 5 appendages to the torso, in the arms, leg
and head. 5 appendages on each of these, in the
fingers and toes
and 5 openings on the face.The human body illustrates the Golden Section
or Divine
Proportion, also.The Divine Proportion in the Body :
The blue line, a golden
section of the white line, defines the distance from the head
to the finger tips
The yellow line, a golden
section of the blue line, defines
the distance from the head to the navel and the
elbows.
The green line, a golden
section of the yellow line, defines
the distance from the head to the pectorals and inside top of
the arms, the width of the shoulders, the length of the
forearm and the shin bone.
The magenta line, a
golden section of the green line,
defines the distance from the head to the base of the skull
and the width of the abdomen. The sectioned portions of the
magenta line determine the position of the nose and the
hairline.
Although not shown, the golden section of the magenta line (also the short section of
the green line) defines the width of the head and half the
width of the chest and the hips. 

The DNA crosssection is based on Phi.A crosssectional view from the top of the DNA double
helix forms a decagon. A decagon is in essence two pentagons, with one
rotated by 36 degrees from the other, so each spiral of the double
helix must trace out the shape of a pentagon.The ratio of the diagonal of a pentagon to its side is
Phi : 1.So, no matter which way you look at it, even in its
smallest element, DNA, and life, is constructed using phi and the
golden section!

The DNA molecule, the program for all life, is based
on the Golden section. It measures 34 angstroms long by 21
angstroms wide for each full cycle of its double
helix spiral.34 and 21, of course, are numbers in the Fibonacci
series and their ratio, 1.6190476 closely approximates Phi,
1.6180339. 
There are many examples of the Golden Section or
Divine Proportion in Nature. For example,the eye, fins and tail all fall at Golden Sections of the
length of a dolphin's body. Phi is frequently expressed in many of Nature`s creations, and by varying the angle between adjacent radii, a number of Natural spirals and leafshapes can be created. The Fibonacci numbers form the best whole number approximations to the Golden number. Plants illustrate
the Fibonacci series in the numbers
and arrangements of petals, leaves, sections and seeds.Plants that are formed in spirals, such as pinecones,
pineapples and sunflowers, illustrate Fibonacci numbers. Many
plants produce new branches in quantities that are based on
Fibonacci numbers.
