Since When Humans Have Fingerprints?

Fingerprint is the identity of any person different characteristics. Because no one who has the same fingerprint makes people so unique identity. Since when has human fingerprints formed? 

It turned out that the fingerprint is a manifestation of language uterus formed since 6 months old fetus. At the age of the fetus already has a characteristic in his fingertips. 


Excerpted from the LIVESTRONG, Wednesday (10/27/2010) developments bearing on the finger and palm marks the threshold of fetal development fingerprints. This condition occurs during the second and third months of pregnancy, whose radius is developing in the womb. 


The Scottish Police Services Authority (SPSA) states the average overall growth of the fetus and the placement of the finger pads to help determine the shape of grooves in the skin that become distinct identity of each person. 


In the third and fourth month of pregnancy found in fetal skin began to change from a thin transparent layer of wax. During this period, the middle layer of skin called the basal layer began to cultivate the inner layer of the dermis and epidermis layers of skin. 


Researchers from the University of Arizona, Michael Kucken and Alan Newall believe that the curves and folds of skin layer take responsibility for the development of fingerprints. 


The first identification occurred in fetal skin is a ridge, the faint outline of the fingertip which created the basis of fingerprints. 


Dr. Michael Roizen of touch said Clinic Clevelend fetus against the structure, density position in the uterus and amniotic fluid in the uterus also determine how the ridge formed. The level of activity and chaos fetus in the womb to prevent the development of fingerprints on each infant. 


At 6 month-old fetus, then the hand and foot prints are fully developed. On each fingertip uama fetus formed three patterns that are categorized as arches, circles and round, with a variety of patterns between them. 


According to SPSA, the pattern found in the fingerprint is divided into two characteristics of the end of the ridge and bifurcation. This is because the order of the final ridge and bifurcation different character in each fingerprint. And these characteristics can be linked as a genetic map of the tendency of certain diseases.
