What are Signs of Fingerprints?

Fingerprints are unique patterns formed by the ridges, furrows, and minutiae (small details) on the surface of the fingertips. 

The presence of fingerprints can be indicated by several signs, including:

The study and analysis of fingerprints is known as dactyloscopy, and it is a critical technique in criminal investigations, as fingerprints can be used to identify suspects or link them to crime scenes.

Handwriting and cave figures are not typically considered types of fingerprints, although they can be used for identification purposes in certain contexts.

Fingerprints are unique to each individual and are based on the physical characteristics of the ridges and furrows on the skin of the fingertips. Handwriting and cave figures, on the other hand, are based on the movements of the hand and the use of a writing implement or tool. While handwriting and cave figures can be used to identify individuals in certain circumstances, such as in forensic handwriting analysis or the study of ancient cave art, they are not considered to be fingerprints in the strictest sense of the term.

All of these forms of identification - fingerprints, handwriting, and cave figures - are examples of individual characteristics that can be used to distinguish one person from another.
