DNA Fingerprinting is so extremely interesting to me. Each and every person has their own set of fingerprints, and none are ever the same. Even identical twins have different fingerprints even if they are semi-similar. Both are hands and fingers have different shapes and lines of the indentions of each person which is what makes us all so different from one another. With the advancements of today's technology scientists are able to identify almost anyone with just the slightest part of a fingerprint or handprint. Fingerprinting has come a long way and is used to identify fugitives everyday. Fingerprints are now the greatest lead to identifying and prosecuting someone who has committed a crime. It is even recommend that once your child has reached an age where they can walk on their own it is important to get a home kit to take your child's fingerprints and other information just in case something bad happens to them. These little things can make and break a case in whether the police can identify your child or not. In crime shows and in real life dusting for fingerprints is one of the first things done to a crime scene. This is the initial lead to all cases.
The identification of fingerprints is known as dactyloscopy. Dactyloscopy is a process of comparing two instances of skin impressions. Human fingers, the palms of your hand, even your toes can determine if the impression came from the same person. Friction ridge is the form in which prints are left, and not even the same person's fingerprints, handprints, or even footprints are exactly the same every time. The smallest of details change with each touch and movement. Just as i am typing right now. Each key I have used has my finger print on it, but each print is different in some minute way. Fingerprint identification is also referred to as individualization. A computer system had been built and edited and revised constantly in order to accurately be able to identify specific fingerprints of the persons in the data base. These computers are operated under a threshold scoring, which is the process of determining whether or not two impressions are from the same person or not. Intentional recording of fingerprinting is typically taken using black ink on a white paper, to show the contrast. The finger is pressed down then rolled to be sure that the entire print is taken. A live scan is done on fingerprints that are invisible to the naked eye, but can be seen with chemical methods and powders. These types of prints are called "latent prints."
So overall fingerprints vary in many ways whether its from size, shape, or the clearness of the impression. So always remember if you plan to commit a crime you can and will be identified with just the slightest of impression left behind. ;)
