Amazing Facts About Your Fingerprint
Fingerprints are a source of interest because of their unique formation and their value in the forensic world, but there are many interesting lesser known facts that fascinate as well.
When most people think about fingerprints, they think of identifying and catching criminals. Almost everyone knows that every fingerprint is different, which is why they are such an effective way to solve crimes, but did you know that not everyone has fingerprints? That’s right. There are three rare diseases, Naegeli-Franceschetti-Jadassohn syndrome (NFJS), Dermatopathia pigmentosa reticularis (DPR) and Adermatoglyphia, that can cause a person to be born without any fingerprints at all. For people with fingerprints, those prints begin to form while we are still in the womb at around three month’s gestation. Everyone, including identical twins, develops their own distinct fingerprint patterns that will grow as we grow and get thicker and shorter as we enter our senior years.
Fingerprints consist of ridges and valleys that form distinct patterns of whorls, loops and arches. We can’t see these ridges and valleys with the naked eye, but they help us grip things every day. Fingerprints can’t be permanently removed, but some activities, like brick laying and working with other abrasive materials, can actually wear down fingerprints. Harsh chemicals and some Chemotherapy treatments can cause fingerprints to be lost altogether. However, these types of fingerprint wear and loss are only temporary. Once we are no longer in contact with those substances, our fingerprints will regenerate to look exactly as they did before the exposure. Had John Dillinger been aware of fingerprint regeneration, the famous criminal might not have used acid to burn away his prints in an effort to escape arrest.
Dactyloscopy, the study of fingerprints, has been used since 1892 to identify criminals and bring them to justice. Because the human body produces sweat and oils that build up on the friction ridges of our fingers, every time we place our fingers or hands on something, the oily residue causes the image of the ridges to transfer to the surfaces we’ve touched. Using a special powder and tape or electronic scanners, fingerprints can be lifted from these surfaces and compared to thousands on file with law enforcement agencies.
Even though all human fingerprints are different, some confusion can occur when using prints to pinpoint suspects. You see, some members of the animal kingdom have fingerprints that so closely resemble those of humans they can actually be mistaken for human prints! While both Chimpanzees and Gorillas have fingerprints, Koala prints are the closest in structure to human prints, and under an electron microscope, the two are practically indistinguishable. So the next time you’re missing a banana or lose a eucalyptus leaf, make sure you accuse the right species. Visit this website for more information on fingerprint service in La Mesa.
