With the development of technology, we often use our fingerprints, which used to replace signatures. Our fingerprints, which begin to form in the womb, are one of the biggest features that distinguish us from other people. What if we told you that our fingerprints can change too?
Yes, we know that sounds interesting. “How can that be?” Let’s take a look at the answer to your question and surprising facts.
Imagine you are a police officer tracking down a notorious murderer…
How do you know which of the people you have detained as a suspect is the right person? She can easily change her style, whether from her clothes. Because of it, it is not difficult to change when plastic surgeries are so common. If your path has passed through detective films once, you can easily answer this question as “Fingerprints!” you have answered. Because it is a proven fact as a result of scientific research that fingerprints are an accurate and reliable method in identification with different data.
Even people with the same DNA have different fingerprints!
Although we think that the reason is related only to genes, the fact that different fingerprints are found even in identical twins with the same DNA is enough to refute this idea. Although the fingerprint does not change under normal conditions, it does change in some unusual situations.
What about these unusual situations?
We can see that people who want to hide their identity rarely achieve this by undergoing some painful operations or as a result of aesthetic procedures. Hormonal diseases or scars on the fingerprint are also among the factors that cause it.
Is every scar on our finger enough to change our fingerprint?
Of course not! Methods such as a deep wound perpendicular to the fingerprint, burning the upper skin of the finger, a deep cut in the form of a zigzag, removing the fingerprint tissue with a knife or sandpaper cause deformation in the fingerprint.
But minor changes in fingerprint are not enough to clearly prevent identification. If the characteristic features taken from the undamaged area are in a suitable number for analysis, experts can identify that person even if the machines are wrong.
Do our fingerprints change as we get older?
So, do our fingerprints age as we get older? When we say the 50’s and 60’s, time flies like water and as we get older, we begin to encounter many changes in our body. We cannot act as quickly as we did in our 20s, and we begin to experience tissue loss in our bones and muscles. As in our entire body, our fingertips lose their skin elasticity over time.
Apart from this flexibility problem, the thickening of the folds in the patterns that make up our fingerprint also causes changes. Of course, the changes that occur in the fingerprint with aging are tolerable.
In other words, our fingerprints that begin to form in the womb are one of our rare features that accompany us until the end of our lives, but changes can be made with external intervention.
