Generally formed only in tetrapods; lungfish have rudimentary VN organs; true VN organs are not normally found in recent fishes, birds, aquatic reptiles, aquatic mammals (Bertmar 1980). Humans: Its presence in many animals has been widely studied and the importance of the vomeronasal system to the role of reproduction and social behavior (through influence on anterior hypothalamus) has been shown in many studies. Its presence and functionality in humans was controversial, though most studies agree the organ regresses during fetal development. Many genes essential for VNO function in animals (such as TRPC2) are non-functional in humans (Liman ER. Use it or lose it: molecular evolution of sensory signaling in primates. Pflugers Arch. 2006;453(2):125-31.) |
