Pheromone Communication via Vomeronasal System Presented by Bobak Manoochehri

Pheromone Pheromones are chemical signals that trigger a response in a member of the same species. In most mammals they are modulators for behavior, which includes maternal care, reproduction, aggression, and alarm responses.

Questions Answered The vomeronasal system evolved from tetrapods millions of years ago. Humans have evolved to have some proof of VNO organs and molecules, but it is unclear if it is functional. Inactive VIR and V2R genes in adult stage of life. The vomeronasal system evolved from tetrapods millions of years ago.
