Subject: Does chirality suggest intelligent design?

Does the fact that only D-sugars and L-Amino Acids are found in 
biologically active macromolecules present a compelling argument for 
intelligent design?  (You don't have to address the issue of 
intelligent design itself)  If there is no energetic advantage to 
either form of these molecules, then why are they so heavily favored 
in nature?
