INTRODUCTION TO RIDGEOLOGY Ridgeology is an evaluative method of friction ridge identification based on scientific principles and procedures, principles and procedures that have been established and verified through years of research. The term Ridgeology refers to a forensic identification science that is associated with all of the ridges on the volar areas and not just on the finger tips as Dactyloscopy or fingerprint identification implies. Ridgeology is not only more encompassing than Dactyloscopy, but has methodologies and philosophies consistent with other forensic disciplines. Ridgeology is an applied science. It has its origins in other sciences such as anatomy, embryology, genetics and neurology. The identification sciences of edgeoscopy and poroscopy are also a part of ridgeology as are areas of dermatoglyphics. Ridgeology's coming of age signifies our commitment to advance into a era of evaluative identification, a process that addresses the infinite variables of friction skin and the degrees of clarity found in friction ridge prints. Ridgeology advances past the confusion of the basic laws of chance, applied to ridge characteristics alone. It addresses the whole ridge detail spectrum. Some forensic identification investigators may feel that the science is so well established that the need to reexamine the intricacies of the identification process is redundant. The science is well developed. However, its methodology is still evolving as are the various sciences on which it is based. The need to remain current is always present. Ridgeology can play a role in this endeavour. One of its main objectives is to identify areas in neurology, anatomy, genetics, embryology, forensic comparison methodology and scientific ethics that form a part of modern friction ridge identification. Knowledge of these disciplines in relation to friction ridge identification is a realm open to study for the scientific and inquisitive mind.
