DNA has now been used to aid criminal investigation for more than 20 years. The vast majority of this evidence has been produced by profiling of human genetic material. However, DNA profiling technology is not restricted to the human genome. Regions of genetic material displaying similar characteristics to markers used for forensic purposes in the human genome have been identified in many other animal species. Although nonhuman DNA profiling has been used for a small number of forensic investigations, the full potential of this evidence type has yet to be realized.
