ABSTRACT
In Chapter 2, various odor-producing sources from a physiological and genetic perspective were explored. In doing so, the door was opened to the understanding of scientic sources of how each person’s body odor is generated and hence how these physiologic processes contribute to an individuality feature. However, it is dicult to dene what a dog is really alerting to when it makes a scent match. It is impossible to say with certainty what process, molecule, protein, or mixture is truly allowing for scent discrimination by a dog’s nose. To further expand on the denition of human scent, this chapter will explore odor from an outside perspective, that of human skin volatiles.
