We just happened to come across the receptors in the nose and the mouth first. It's intriguing to think this role may be pre-dated by their chemical-sensing capacities in other organs. Some see it as unlikely given that they are present in much higher numbers in the nose and mouth,Michael Kors Wallet, but others disagree. "We call these taste receptors, but maybe they aren't taste receptors," says Ben-Shahar. "Maybe they were doing a lot of things before. Recycling is a very strong theme in evolution." Cohen puts it more strongly. "I'm willing to bet that these bitter receptors were on the airway before they migrated to the tongue, that this is where they really belong."
