Genetic basis of olfactory communication in primates

Article Abstract:

The genes involved in olfactory communication in mammals via the vomeronasal system are summarized, and studies investigating these genes in primates are reviewed. Only five potentially functional vomeronasal receptor genes (V1RLs) are found in humans, and only one of these (V1RL1) is studied in other primates. V1RL1 has become a pseudogene repeatedly during primate evolution, but patterns of natural selection on primate V1RL genes demonstrate that this gene family diverged throughout at least part of primate evolution.

Grooming relationships between breeding females and adult group members in cooperatively breeding moustached tamarins (Saguinus mystax)

Article Abstract:

A study to examine the grooming behavior in a cooperatively breeding primate species is presented. The results conclude that grooming might be a mechanism used by female moustached tamarins to induce mate association with the male.
