Innately found in the DNA structure of each and every individual, fingerprints are actually formed in the early embryonic stage with the infinite knowledge and might of the Creator. No two fingerprints have ever been found to be identical in every detail, despite billions of comparisons. This miracle alludes to the omnipotence and omniscience of God. Fingerprints are never exactly alike, but unique for each individual, except identical twins. To achieve this requires the infinite knowledge of the one who distinguishes the fingerprints of all the living and dead, as well as those who are to be born. The fingerprints of identical twins are identical because the same egg has been inseminated by the same sperm and has then split into two, and thus the two babies have exactly the same DNA structure.
Fingerprints are friction whirl formations on the skin of the fingertips that are perpendicular, circular, oval, or made up of patterns parallel to each other. Fingerprints are deposited by the natural secretions of the eccrine glands which are present in the skin of the fingertips. When we touch an object, natural sweat secretions are discharged from the glands at the fingertips and these secretions remain on the surface in the shape of the whirls.
Fingerprints on the objects that human beings touch are generally created by the secretion from glands. 99% of the secretion produced from the glands is water. The remaining 1% is of fatty acids, ethers, amino acids, and salts. It has been found, in contrast to the fingerprints of adults, which include long carbon chains linked by ethers, that the fingerprints of children have mostly non-etherized, short chains of fatty acids. These short chains of fatty acids on the fingertips of children are volatile. Thus, the fingerprints of children evaporate in 24 hours, while those of adults remain for longer periods. For this reason, fingerprint detection should be done as soon as possible in crime scenes in which children are involved.
