Dermatoglyphics is the analysis of fingerprints, palm prints and foot prints. Everyone has his/her unique prints, therefore, it can be used in criminal forensic analysis to proof identity.
Western scientists believe that dermatoglyphics is the DNA genes in the human body that reflected in appearance. Although everyone is different prints, but certain patterns can be found in our prints. Skin begins to develop in the embryo in the 13th week, and it is formed in the 19th week. It is closely related to the infant’s brain development. The distribution of prints is considered to represent brain cells’ proportion and distribution in each of the brain lobes.
In the nineteenth century, British eugenicist Galton (Sir Francis Galton), had collected many human fingerprints and identify various lines of statistical frequency. He was the first person who proposed that there is a connection between human prints and genetics. In the 1930s, U.S. scholars began to use prints to identify whether a newborn has down syndrome and other potential mental illnesses. Until now, foreign scholars claim that they understand enough of human prints to judge the potential of human brain.
Currently, human prints can be categorized as one of the three main types (whorls-shaped, arch-shaped, and loop-shaped). It is subdivided into eleven basic types, from which many types of analysis have been derived, some focus on the analysis of left brain and right brain, some believe that the print on each finger reflects different abilities. (Thumb ︰ action and execution; index ︰ logic and creativity; middle finger: limb motor ability and art appreciation; ring ︰ power of voice recognition; little finger ︰ text image discerning ) As for the foot pattern, it can determine whether one has congenital diseases. It is as equally important as fingerprints.
