I appreciate your one-word answer. With all due respect, I don't know whether
anyone in sbe makes anything of  ":Proteins" as an answer to my
question (How
genes determine bird morphology). To me it makes no more sense than other
one-word answers ( "God", Lipids", "Atoms",
"Environment", etc.) do. No word
has ever been used as a substitute for a mechanism, and a mechanism is exactly
what my question asks.  

However, you have a chance to prove that your answer makes sense: elaborate how
 a protein or a group of proteins would provide information for the complex and
highly specific arrangement of billions of cells of tens of different types of
cells in the process of the development of any organ.
Please, illustrate with a SINGLE example (don't forget, we are fed up with
general unsubstantiated statements).

Thank you,
