Pee-Pee Observations

Behaviors that confer an elevated fitness on the individual are often passed down through the generations--this is an essential element of natural selection and evolution. For example, intricate mating calls may be linked with other phenotypic traits that improve reproductive success, and often they reduce the need to expend energy visually searching for mates or finding the wrong sex or species after searching--less time searching means more time for mating, and thus more offspring. Its easy to see how behaviors may be inherited. Some behaviors, however, seem to have little to no evolutionary benefit--as is the case with many human traits, since the environment rarely dictates our fitness. As I am an astute observer of behaviors (it was part of my original dissertation), I'm often puzzled by some of these displays when it comes to peeing. Apparently there are many convergent or inherited behaviors that are common place in bathrooms from sea to shining sea...I'll outline the ones I just don't get:

• The need to spit into the urinal while unzipping the fly
• Peeing with no hands
• Rocking back n forth or side to side
• Propping oneself up on the wall or urinal divider with one arm
• Groaning
