Dermatoglyphics (from ancient Greek derma = skin, glyph = carving) is the scientific study of fingerprints. The process of fingerprint identification had been used for several hundred years now.
Since 1920s, Dermatoglyphics has been studied in the medical field, especially in relation to genetically-linked diseases. The study has absolute scientific basis, with 200 years of research. It has been analyzed and proven with evidence in anthropology, genetics, medicine and statistics.
The fingerprint patterns are formed from the external ectoderm and usually occur during the fetal development stage, 13 to 19 weeks after fertilization. Through research, geneticists have proven that Dermatoglyphs formations are controlled by chromosomes, and the patterns are influenced by polygenetic inheritance. These genes do not exhibit dominance, and they are very resistant to acquired changes from the environment. Using their morphologies, the patterns can be classified into two categories, namely “ridges” and “furrows”. During the seventh week of pregnancy, vertical thumb creases (thenar contours) begins to appear on the palm of the embryo. Two weeks later, remote and proximal horizontal creases (hypothenar contours) begin to form.
Hirsch and Schweicher discovered that prior to the formation of dermatoglyphs, the dermal nerves and blood vessels are arranged in an orderly fashion. This led them to believe that the nervous and vascular systems determine the formation of dermatoglyphs. Consequently, they also established the correlation between the Dermatoglyphics patterns and one’s personalities.
From the anatomical point of view, the human hands dominate all other organs in terms of relative importance. This is why the brain dedicates the majority of approximately two hundred million nerve endings to the hands. In other words, the hands are sources of physiological and psychological information waiting to be tapped, hence the increasing importance in the field of Dermatoglyphics.
Brain – Fingerprint relationship
- It has been scientifically proven that no two people can have the same fingerprints.
- Once a child is born, his/her fingerprints are completely developed and they remain unchanged till the end of their life.
- Fingerprints start developing when the child is in the mother's womb from 13th week of pregnancy.
- This is the same period when the brain of the child also starts developing. Development of fingerprints and brain happen simutaneously.
- It has been scientifically proven that the children whose brain is not developed, their fingerprints are also not developed.
- It is a mental disorder, congenital in nature and called "Down Syndrome"
- A Down Syndrome patient is intellectually disable with following characteristics:
- Mental retardation-100%.
- Small teeth-60%.
- Flattened node-60%.
- Separation of abdominal muscles-80%.
- Short neck-50%.
- Congenital heart diseases-45%.
- Undeveloped fingerprints-90%.
- ATD angle-More than 55 degree.
