Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
In modern use, the term forensics is often used in place of "forensic science." The word "science", is derived from the Latin word for 'knowledge' and is today closely tied to the scientific method, a systematic way of acquiring knowledge. Taken together, forensic science means the use of scientific methods and processes for crime solving.
An example from the book, “The Psychology and Sociology of Wrongful Convictions: Forensic Science Reform,” there was a profiling error, in which this woman was raped and slaughtered by a serial killer. The suspect was named the Boston Strangler and investigators worked hard in trying to gather a profile for this criminal.

Forensic psychology – study of the mind of an individual, using forensic methods. Usually it determines the ...
The first use of RFLP analysis in forensic casework was in 1985 in the United Kingdom. [4] This type of analysis used variable number tandem repeats (VNTRs) to distinguish between individuals. VNTRs are common throughout the genome and consist of the same DNA sequence repeated again and again. [ 5 ]
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus ; which is inherited from both parents, and the mitochondria ; inherited maternally.
According to the Times, the study found that “in two-thirds, it was the direct cause of death, mostly in combination with other drugs.” It was a misreading of the study. Its author, Tor Seldén of Sweden’s National Board of Forensic Medicine, told The Huffington Post in an email that the Times’ claim “is not supported by our findings.”
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
