The Secret Behind Human Fingerprints

Fingerprints (United Kingdom: fingerprint) is the result of reproduction of finger good tread are deliberately taken, stamped with ink, as well as the scars left on objects because it never touched the skin of the hands or feet. [1] the skin of the soles is the skin on the palms of the hands starting from the base of the wrist to the fingertips, and all the skin part of the sole of the foot starting from the heel to the tip of a finger on the area where there is a fine line that protrudes out one Another separated by fissures or grooves that form certain structures. It is said that every trace of the Groove, arches, and waves that are on the ends of the fingers of every person no. Formation of patterns that are found in each of the fingers of one hand also varies. That's why when you came abroad, then Your fingerprints will be required by immigration officials of the country.

Based on the data obtained through the, the chance of someone finding a set of other fingerprints really duplicate direct from your own only one among 64 billion possibilities. But until the article is created, not discovered there were two people in the world who have exactly the same fingerprint. [2] Even a pair of identical twins also have finger cap are completely different, even though they share the same DNA. Lho kok can?

Before further find out the reason behind this uniqueness, it is important to know why the man could have a fingerprint, and then understand how fingerprinting can be formed.

[3] the most widely accepted Theory States that the fingerprints are formed from a fetus that is busy moving there to let the amniotic sac wall touch thus creating a unique mold.

Human skin has multiple layers and each layer has a sub-layers. The Middle skin layer called the basal layer, was squeezed in between the layers of the skin (dermis) and the outer layers of the skin (the epidermis). In the fetus, the basal layer is growing faster than its neighbors, so the layers are curved and folded in any direction. While the basal layer continues to grow stretched, this pressure led to the two other layers of skin come into interested; cause the epidermis crushed folded into the dermis.

Nerves are also said to play a role in the process of the formation of fingerprints, because experts suspect nerve is the origin of the attractive force of the epidermis. This crease process will continue to happen until ultimately produce complex and unique patterns that we see in our fingertips nowadays. The following is an explanation via video so that you can better understand.


Fingerprint identity marker is permanent even when someone dies, fingerprinted will still be there so it is very easy to identify the bodies. This is because the fingerprint pattern code embedded so deep below the surface of the skin so it arguably permanent. Although it could be worn out from exposure to extreme conditions, fingerprints would grow back so exposure to abrasive, sharp, or the condition of the heat died down.

In some cases, damages the fingertips can be very severe and affects the inside lining of a leather plant, resulting in a permanent change in fingerprints. The experts reported that the resulting scars — either from burns or cuts sharp objects — can take terkode permanently follow the fingerprint pattern.

There are three basic types of fingerprint patterns you may have heard that everyone has different fingerprints. But there are certain patterns shown by the cap finger. Fingerprint is divided into 3 basic types namely screw (whorl), loop (loop), and the arch (arch). The arch is further broken down into plain arches and arches of a hood. Here is a diagram of the fingerprint pattern types so that you can distinguish it more clearly.

Three types of fingerprint patterns (source: perbuktian texture Pattern that is on the tip of the fingers you have two common characteristics for each fingerprint: the tip of the Hill and the branch. The sequence of each end of the Hill and branching is different on each fingertip. The tip of the screw is a hill that ends abruptly; branches are created from one end of the hill which divides two and continues as two new lines of different directions.


Then, why is everyone's fingerprints can be different? Pattern mold cap your finger when it was settled (permanent) like when you were a fetus was 17 weeks. This development does not only depend on genetic factors, but also the unique physical conditions. Countless factors that affect the formation of the pattern can be estimated; including blood pressure, oxygen levels in the blood, maternal nutrition, hormone levels, the position of the fetus in the womb at certain times, the composition and thickness of the amniotic fluid that is swirling around the baby's fingers as they touch the walls of the amniotic sac and surrounding it, right down to the strength of finger pressure while the baby touch the surrounding environment. The researchers believe that the myriad of variables it can decide how each mold grooves at the fingertips of every human being can be formed.

The level of activity of the fetus and the diversity of conditions in the womb, generally prevents fingerprints evolve in the same way for each fetus. The whole process of growing flower child in the womb is extremely chaotic and random so that in all of human history, there is almost no chance that exactly the same patterns can be formed twice. Thus this also means that prints on each finger of the hand of the same owners will also be different. Likewise with the other hand side.

Did you know that there is a congenital genetic disorder that can make a person born without fingerprints? People with the syndrome Naegeli-Franceschetti-Jadassohn (NFJS), Dermatopathia Pigmentosa Reticularis (HOUSE of REPRESENTATIVES), or Adermatoglyphia are known to have no fingerprints at all [4]. Every human being, including those who were born identical twins have a distinctive fingerprint patterns and different breathtaking. In other words, one human identifiers present on their fingertips.

The uniqueness of fingerprints found recently discovered in the late 19th century. Before the majority of people assume if a fingerprint is a regular slope-the slope without any special significance. But the 14 centuries ago, through the Quran, God refer to fingerprints, which at that time could not attract people's attention. Currently, through the progress of science and technology of the world especially the interests of the world of forensics, we understand that the fingerprint turns out is very important.

It is also described in one of the verses of the Quran in surah Al Qiyamah, which means:

"Does man think that we will not collect (back) bone belulangnya? Not so, our actual power draw up (back) the radius of its fingers perfectly. " (Q. S Al Qiyamah; 3-4)
