Studies by a USC researcher suggest that evolution eliminated a physiological tool in humans critical to detecting pheromones. Emily Liman traced the disappearance of the vomeronasal organ in our ...

Third, and perhaps more importantly, almost all of the genes involved in protein expression of a functional vomeronasal organ are pseudogenes in humans dating back as far as 23 million years ago ...

In a study published by the British journal Nature, the team engineered female lab mice so that the rodents lacked a gene called TRPC2, effectively short-circuiting the so-called vomeronasal organ.

Mice on the prowl for a mate use an essential but unexpected organ - a 'second nose' which figures out gender, status and even if romantic feelings are mutual, scientists have discovered ...

The vomeronasal organ is indeed rudimentary or absent in species with a disrupted TRPC2 gene. Caribbean nectar-feeders also exhibit derived olfactory turbinal morphology and a large olfactory recess ...

A human's vomeronasal organ seems to disappear during fetal development. The presence of human pheromones is still hotly debated, though.

The vomeronasal organ, a vital sensory structure, had never formed inside this dog’s snout, and a related structure, the septum pellucidum, was also missing.

The vertebrate vomeronasal organs may have evolved from enlarged fish olfactory folds (nasal diverticulae) with an accumulation of specialized olfactory receptors. Different tetrapod lines are ...

For cats however, the vomeronasal organ is a powerful tool that enables them to interpret important social information in their environment. To quote Scottish novelist and poet Sir Walter Scott ...
