Charles Darwin once said “False facts are highly injurious to the progress of science, as they often last a long time; but false opinions, if supported by some evidence, do little harm, because everyone takes a healthy pleasure in demonstrating their falsity” (Brainy Quote, 2013). Trace evidence is included as one of many studies that help prove a suspect wrong. Trace evidence is the study that identifies and compares specific types of trace materials that may be transferred during the commission of a violent crime. Physical contact between a suspect and a victim can result in the transfer of trace evidence. The identification and comparison of trace material can often link a suspect to becoming guilty. The educational requirements for trace testing consist of several years of field education and training. The history of the tracks has shown that the technology has been of great reliability in the 21st century. Large numbers of crime cases have been solved thanks to traces of evidence, because all it takes is a little hair, a follicle or a fiber to fall out and everything starts to come together. Tracking evidence has been an incredible solution to cases, even if it takes more than thirty years to do so. Trace evidence is a study that identifies and compares specific types of evidence that can be passed on as trace material during the commission of a brutal crime. Trace materials include animal hair, human hair, textured fibers and fabrics, rope, feathers, soil, grass, and building materials. For animal hair and human hair, tests are performed to determine whether the hair is human or animal. If the fur is animal, it is possible to determine its species and breed. If the hair is human, racial characteristics, body area, length, root type, treatment and dam... at the center of the document... numerous microscopic studies on the hair of most animals. As a result, during one of the first legal cases involving hairs, Rosella Rousseau was forced to confess to the murder in 1910. In 1945, Frank Lunquist developed the acid phosphatase test for sperm, which helps find the DNA of a possible criminal . In 1950, Max Frei-Sulzer developed the tape lift method of collecting trace traces to make things like hair or fibers more transportable for investigators. Finally, in the 1960s, Maurice Muller adapted the Ouchterlony antibody-antigen diffusion test for the precipitin test to determine species of different animal types, which refers to the feather test carried out to detect traces. In conclusion, all of these past historical achievements of these individuals have made tracks more convenient today than they would be if none of these inventors dedicated themselves to them..
