On th. In 1910, Thomas Jennings managed to escape from murder territory, but left behind a small, important suggestion. The clue that chooses his fate before the law as a murderer is a fingerprint.
In addition to the case handled by Inspector Eduardo Alvarez in Argentina, Jennings' case was the first, in a criminal investigation, to make fingerprints evidence of a crime.
After the Jennings case, the role of fingerprints became vital in the forensic investigation. This unique identity marker is ideal for leading justice officers to track down the perpetrators of crimes.
Of course, fingerprints are not only useful to identify each human being. Regardless of the need for forensic investigation, fingerprints include other benefits.
"People have two inspirations when it comes to fingerprinting, which is to help strengthen the grip, and that helps improve touch perception," said Professor Roland Ennos, a biomechanics and biology researcher at the University of Hull, in the UK as quoted from Live Science.

The strokes on the fingerprints create friction on the human hand and the surface of the object it touches. Thanks to this condition, humans are able to grip the wet surface, resulting in the hands not slipping.
Fingerprints are also useful to prevent blisters. According to Ennos, fingerprint strokes include making the skin not easily blistered. While at the same fitting, fingerprints include allowing the skin to stretch at the right angle.
Meanwhile, Georges Debregeas, a biologist at Sorbonne University in Paris, France, stated the benefits of fingerprinting in more detail. According to him, on our fingers there are four types of mechanical receptors, or cells that respond to mechanical stimulation (such as touch).
One of its receptors is pacinian blood cells, which are contained approximately 2 millimeters below the surface of the skin at the fingertips. These receptors mediate perception of texture.
When a human touches an object's surface, its fingerprints will transmit vibration frequencies to highly sensitive pacinian blood cells. Thanks to this, mechanical receptors are able to hold sensory information.

However, what are the benefits of this sensory information for human life? For thousands of years, human hands have been a necessary tool for finding and producing food. Finger sensitivity to texture is very beneficial to detect the type of food that is worth consuming.
"The reason why we have to detect and sort by texture is because we want to handle good food comes from bad food," said Debregeas. Touch sensitivity helps humans to avoid rotten or infected food.
In addition to humans, fingerprints and pacinian blood cells belong to other animals, such as chimpanzees and koalas, who rely on touch sensitivity to find the right food.
Debregeas's theory also deals with Ennos's statement, regarding fingerprints capable of strengthening the grip. "Fingerprints are very likely to correct the ability immediately when we will grip the object," added Ennos.
For example, when a human hand slips onto something, fingerprints help detect surface changes so that the hand is able to adjust the grip. It states that the senses of human touch and grip develop simultaneously.
