Why do we have fingerprints?

Fingerprints are unique to each individual and serve several purposes, primarily enhancing the sense of touch and providing grip. The ridges and patterns of the fingertips help increase friction, making it easier to grasp objects. Additionally, fingerprints may have evolved as a way to improve tactile sensitivity, allowing humans to better explore their environment. The uniqueness of fingerprints makes them useful for identification in forensic science and security, as no two people have identical prints.
