Law Enforcement has used forensic science for years help solve puzzling crimes. But not to many people know just how long the art of forensic science has been around for example evidence of fingerprints were found in paintings & prehistoric rock carvings made by humans . The chinese have probably used forensics much longer than most civilizations. For example back in the 700’s they used fingerprints to find out the identity of documents ; clay sculptures.
What made this unusual was that there was no form of classification system back then. They were pretty much learning as they went along. They probably helped out today’s forensics more than we actually know .
