When virtually everything except apparently insects on this planet gets a whiff, the scent molecules travel up the nose and attaches onto a G-protein coupled odorant receptor on the cell surface, starting of a chain reaction that ultimately sends information to the brain.

Although there were varied proposals as to what kind of molecules might interact with odorants, there was compelling evidence that olfactory transduction involved G-protein induced increases in cAMP.

After first referring to the Wnt signalling pathway and G-protein control of cellular calcium, Dr. Miller concludes, "Just look at the details, and you'll immediately abandon all thoughts that biological systems were designed with any intelligence whatsoever."

What that means is that the sensory stimulus is received by a receptor molecule specific for that stimulus, which then actives a G-protein on the intracellular side of the cell membrane, which in turn activates an effector enzyme that modifies the concentration of second messenger molecules in the cell.

The G-protein that links receptor and effector is the common element that unites a whole battery of senses.
