A major component of social chemosignaling in macrosmatic
mammals is conveying of social status, namely dominance/submissiveness.
Furthermore, interpretation of some behaviors is confounded because they are related to olfaction in macrosmatic
species such as rodents and carnivores, and it is not clear that these behaviors have counterparts in microsmatic species like man.
The differences between the human and canine nasal passages that make dogs more macrosmatic
(keen-scented) lie not only in the amount of nerve receptors and cilia in its tissue (or epithelium) used to pick up scents, but also in the way the two sections are separated in dogs and other keen-scented animals.
