Super food.jpg
(Even super-tasters would enjoy this super food!)

I believe that the reason these "super-senses" exist, such as insects' vision, dogs' olfactory sense, etc. is to permit their survival. For example, insects eternally need to be on high alert due to their relatively small size. Dogs needed a strong smell in order to find their pray. These traits would be more common in humans, too, if it helped for their chance of survival. For example, if most foods that humans consumed were poisonous and only a "super-taster" could use his tasting skills to test which ones, they would likely have a higher survival rate. This survival rate would lead to a higher reproduction rate and thus "super-tasting" would be standard among humans.

Yet in reality, this is not helpful. That is why the "super" genetic mutations of senses in humans are rare. An example of this, again, is the super-taster. There likely is no unique advantage to this skill. In fact, it could be harmful, because infants and other youth would be pickier about their food, which would potentially lead to poorer nutrition. Although these super senses are neat human bodily tricks, the lack of advantage means that they are not likely to spread in the near future.
