Using the thumb fingerprint to recognize an individual in any forensic case has become old fashion with the technological advances nowadays. The revolution that has been made was when scientists were capable of turning the DNA into a fingerprint unique for each individual. This was possible after developing techniques that are capable of comparing DNA from different individuals and being able to recognize each as being unique to its holder and being able to match it. This is possible using blotting, where chunks of DNA run through a gel and can we can compare DNA from different individual relying on these brands that the chunks would make. This technique is being used in forensics to match the DNA found on a murder or rape scene to the suspect and it is approved by the court as being an actual evidence.
