Fingerprints are unique patterns that are found on the fingertips and have been a useful tool for identifying a person. Fingerprints are formed by grooves at the tip of the fingers. Although the reason these grooves are formed is not exactly known, we assume that this surface helps hold objects by creating friction between the finger and the object. These grooves for friction are not unique to humans and have been observed in some primary mammals.
