If, through the process of evolution, a species develops a greater range of foods, what do you think comes first: the food or the receptor? Would a species start eating something new (say, something with a sweet taste) and later develop the appropriate taste receptors, or would the taste receptors evolve first and then lead the animal to a new taste?
