Primates have remarkable visual adaptations compared to most other mammals, long explained as associated with a trade-off with olfaction (smell). However, as more information comes to light on the role of olfaction in primate behavior it becomes apparent that olfaction is not a trivial sense. Even humans use smell to communicate, albeit in subtle ways, and the olfactory systems of the lemurs and lorises are very well-developed. Olfaction, however, is actually comprised of two distinct systems - the main olfactory and vomeronasal systems. These two systems overlap in many functions, but the main olfactory system is considered fairly generalized while …
