In 1910, Thomas Jennings managed to escape the murder scene, but left behind a small, important direction. The clue that determines 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 for identifying each human being. Regardless of the importance of forensic investigation, fingerprints include having other functions.
"People have two inspirations about fingerprints, which 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 situation, humans are able to grip the wet surface, causing the hands not to slip.
Fingerprints are also useful to inhibit blisters. According to Ennos, fingerprint strokes include causing skin not to lightly blister. While at exactly the same, fingerprints include allowing the skin to stretch at the right angle.
Meanwhile, Georges Debregeas, a biologist at Sorbonne University in Paris, France, described the fingerprint function in more detail. According to him, on our fingers there are four styles of mechanical receptors, or cells that respond to mechanical stimulation (such as touch).
One of its receptors is pacinian blood cells, which are 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 send vibration frequencies to highly sensitive pacinian blood cells. Thanks to this subject, mechanical receptors are able to hold sensory information.

However, what does this sensory information do for human life? For thousands of years, human hands have been an important tool for finding and processing food. Finger sensitivity to texture is very beneficial benefits of detecting the style of food that is worth consuming.
"The reason why we have to detect and sort by texture is because we want to overcome good food from bad food," debregeas said. Touch sensitivity helps humans to stay away from 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 was also shared with Ennos' statement, regarding fingerprints that were able to strengthen the grip. "Fingerprints are very likely for us to correct the ability immediately precisely 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. This suggests that the senses of human touch and grip develop together simultaneously.
