Every fingerprint is different

The fingerprint

Everyone has their own fingerprint. Every fingerprint is different and an unmistakable means of recognizing a person.

So nobody in the world has the same fingerprints as you. Even as an adult, you still have the same fingerprints as you do now.

The marks left by your fingers can look like arcs or loops, depending on how the finger is shaped at the tip.

If you look at your finger, you will see a lot of tight lines. these are the so-called skin ridges. They leave fingerprints and help you grip and hold.

The fingerprint helps the police solve crimes because the pattern of your finger is unique, making it easier for the police to find the perpetrator. Even identical twins have different fingerprints. Even after an injury or a burn, the pattern is retained. Many people today have their fingerprints taken and stored on their computers. In this way, police around the world can compare different people's prints.

 

Did you know that?

You can also make prints with your toes. The lines and furrows on the toes and soles of your feet are designed to protect you from slipping.

Chimpanzee fingerprints look very similar to ours.

The squirrel also leaves fingerprints.

 

How was the fingerprint invented?

Wilöliam. J. Heuschel, a British government official who lived in India and paid pensions to Indian soldiers monthly, discovered the uniqueness of fingerprints.

The officer suspected that several soldiers received their pensions several times under a false name. With so many Indian soldiers, there was no way he could remember their faces. He was right - when he compared their fingerprints, some of them matched.

What is a genetic fingerprint?

The genetic fingerprint has nothing to do with fingers. When it comes to genetic fingerprints, the police look for traces of hair, skin, saliva or semen. In these tiny cells one finds information about a person that is unique to each person.

These cells are then examined in the laboratory.

Genetic fingerprints are primarily used to identify perpetrators or dead people and to clarify father or motherhood.
