Loss of eyes associated with increased chemosensory abilities leads to a hypothesis of increased tactile sensitivity for food choice and mate choice.
This fact can be explained to a general audience by saying that food odors cause us to eat what causes us to produce pheromones that cause us to associate, or not associate, with other people. In this context, pheromones are social odors.
The all-too-common visual approach to human physical attraction is akin to the visual perception of attractive foods being causal to the development of food preferences.
There is only one animal model for food choice and for mate choice.
