Scientists recently found a 13th cranial nerve, which was so small and undeveloped that it was no surprise that it had been missed for hundreds of years.
The truly remarkable thing about this anatomical discovery was not the merit of the discovery it’s self, but rather the origin of such nerve. Biologists simply could not comprehend the idea that this 13th nerve, which is now called cranial nerve zero, was 100% analogous (that is, the same) as that of the vomeronasal organ in reptiles.
