An evolutionary explanation to the fact that bitter tastes threshold concentrations are lower than the concentration threshold of salt or sweet tastes. Introduction: The gustatory receptors are able to detect the different types of tastes on the tongue. However, every taste receptor has a threshold concentration (concentration at which the taste can be detected and discriminated from water) above, which the quality (whether the taste is bitter, sweet or sour) of the taste is identified. The bitter tastes are identified early due to lower threshold concentrations while salty and sweet tastes have a higher threshold concentration.
