In animals the sensory capabilities evolved over hundreds of millions of years. It is therefore not surprising that different sensory aspects use similar transduction mechanisms. In terms of transduction (i.e., the way energy or chemicals are sensed and transduced into an electrical signal), which distinct human sensory systems use the same molecular mechanisms? Please list two pairs of systems and explain the similarity.
