Forensic science or forensics is the application of a range of different sciences to answer questions that are of interest to civil or criminal law. This broad medical topic can be subdivided into various disciplines which include forensic anthropology, archeology, biology, entomology, geology, meteorology, odontology, pathology, toxicology and criminalistics. Criminalistics is also a broad discipline that makes use of various sciences to examine biological, trace, impression and ballistic evidence left behind in a crime scene
Forensic science is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure.
Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.
In addition to their laboratory role, forensic scientists testify as expert witnesses in both criminal and civil cases and can work for either the prosecution or the defense. While any field could technically be forensic, certain sections have developed over time to encompass the majority of forensically related cases.
