Fingerprints are the bumpy skin on the ends of human fingers. The patterns and fingerprints formed can increase the friction when the hand touches an object, making it easier to exert force and grasp the object. It is naturally formed during the process of human evolution.

It is the different pressing directions of the subcutaneous tissue on the finger belly surface that create these different patterns. shape. Studies have shown that if someone's fingertips are high and round, their fingerprints will have a spiral pattern. Scientists have been able to use models to recreate the more common fingerprints, as well as replicate the formation of less complex, rare fingerprints.
