Research

Dermatoglyphics is the study of ridged skin patterns (also known as dermatoglyphs) which can be found on fingers, palms, toes and soles. These 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 dermatoglyph 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 dermatoglyphic 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.

Since 1823, scientists have discovered that fingerprints and innate intelligences are related. Through medical researches, it is found that fingerprints are formed during the 13th to 19th prenatal week. The neocortex is developed during the same period as well.
This principle has been verified by many researchers and it has been published in various literatures as well. According to prime genetics research sector in China, fingerprints are formed during the 13th to 19th prenatal week. Fingerprints are invariable throughout the lifetime, unless some form of disturbances are introduced during the development stage that alter genetic composition.
From then onwards, scientists integrated genetics, embryology, dermatoglyphics and neural science with the theory of multiple intelligences. With that, a person’s personality and talents can be analysed and classified accordingly.

According to Sunday Times, several scientist from Barcelona University studied the fingerprints of hundred of students and concluded that fingerprints reflect intelligence. Intellectually disabled people usually have fingerprints that are substantially different than that of a normal person.
The scientist discovered that among the hundred of students studied, the intellectually disabled children have fingerprints that have more arches and circular patterns. Besides, their palm prints have more abnormal patterns than their normal counterparts. Scientists commented that the Simian ridge found across the palm is most related to a person’s intellect.
