Forensics or forensic science is the application of science to questions which are of interest to the legal system as well as social sciences such as archaeology.
For example, forensic pathology is the study of the human body to determine cause and manner of death. Criminalistics is the application of various sciences to answer questions relating to examination and comparison of biological evidence, trace evidence, impression evidence, drugs and firearms. Forensic odontology is the study of the uniqueness of dentition, and forensic toxicology is the study of drugs and poisons, and their effects on the human body.
The use of the term “forensics” in place of “forensic science” could be considered incorrect; the term “forensic” is effectively a synonym for “legal” or “related to courts”. However, it is now so closely associated with the scientific field that many dictionaries include the meaning given here.
