Forensic biology is the science of using biology to solve problems or mysteries in both criminal and civil investigations as well as other medical sciences, such as forensic anthropology and evolutionary biology. In general research work, forensic biology is often used in combination with archaeology and anthropology to ask questions and find answers about death using fossil records of an organism. For example, performing a large scale study about the presence of heart disease in the Ice Age may provide important clues to human medical history or how the environment affects evolution and life. In law enforcement, meanwhile, forensic biology is used to investigate crime scenes, identify victims or suspects, and can be used to exonerate the wrongly accused.
