Abstract
DNA Analysis has been an important tool for forensic investigations, used to scientifically link an individual to a crime, and provide statistical relevance to the possibility that any other person could have contributed that biological evidence. This analysis has predominantly focused on human biological evidence, but animal-sourced evidence can provide equally compelling information to an investigation. Such analysis could be useful in cases that involve trace transfer of animal hairs (such as from a pet of the perpetrator onto a victim), cases that involve an animal directly (such as a animal cruelty cases), or cases that involve wildlife (such as the trade of endangered animal parts). Studies show that ~50% of US households contain a dog or cat, and that wildlife trade is estimated at $20 billion a year. However, animal DNA evidence has been used in only a small number of courtroom cases. This research seeks to outline the potential, limitations, and necessary development in research and technology to apply DNA analysis to animal evidence.
