India DNA, the language of life yields information beyond our imagination, both in health or disease. DNA fingerprinting is a tool used to unravel all the mysteries associated with the oral cavity and its manifestations during diseased conditions. It is being increasingly used in analyzing various scenarios related to forensic science. The technical advances in molecular biology have propelled the analysis of the DNA into routine usage in crime laboratories for rapid and early diagnosis. DNA is an excellent means for identification Address for correspondence: of unidentified human remains.

  • An Investigation Into the Foundational Principles of Forensic Science
    Department of Chemistry An Investigation into the Foundational Principles of Forensic Science Max Michael Houck This thesis is presented for the Degree of Doctor of Philosophy Of Curtin University of Technology February, 2010 i Declaration: To the best of my knowledge and belief this thesis contains no material previously published by any other person except where due acknowledgment has been made. This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Signature: __________________________________ Date: _________________ ii Abstract This thesis lays the groundwork for a philosophy of forensic science. Forensic science is a historical science, much like archaeology and geology, which operates by the analysis and understanding of the physical remnants of past criminal activity. Native and non-native principles guide forensic science’s operation, application, and interpretations. The production history of mass-produced goods is embedded in the finished product, called the supply chain. The supply chain solidifies much of the specificity and resolution of the evidentiary significance of that product. Forensic science has not had an over-arching view of this production history integrated into its methods or instruction. This thesis offers provenance as the dominant factor for much of the inherent significance of mass-produced goods that become evidence. iii Presentations and Publications Some ideas and concepts in this thesis appeared in the following presentations and publications: “Forensic Science is History,” 2004 Combined Meeting of the Southern, Midwestern, Mid Atlantic Associations of Forensic Scientists and the Canadian Society of Forensic Scientists, Orlando, FL, September. “Crime Scene Investigation,” NASA Goddard Engineering Colloquium, Goddard Space Flight Center, Greenbelt, MD, November 2005 “A supply chain approach to evidentiary significance,” 2008 Australia New Zealand Forensic Science Society, Melbourne.
