PATHOLOGY

Detailed explanation-1: -For over 100 years scientists have believed that the purpose of our fingerprints is to improve our ability to grip objects. But researchers discovered that fingerprints do not improve grip by increasing friction between the skin on our fingers and an object.

Detailed explanation-2: -One of the most important uses for fingerprints is to help investigators link one crime scene to another involving the same person. Fingerprint identification also helps investigators to track a criminal’s record, their previous arrests and convictions, to aid in sentencing, probation, parole and pardoning decisions.

Detailed explanation-3: -Not only do your fingerprints help to identify you, but the patterns made of tiny ridges in your skin that help you to hold on to things.

Detailed explanation-4: -Summary: Everyone thinks that they know what fingerprints are for: to improve your grip’s friction. But it turns out that this urban myth is wrong. Scientists have proved that instead of improving your grip, fingerprints drastically reduce friction.
