The Chicken or the Egg?

While scanning the poultry at your local market, you might ask the question, 
which came first, the chicken or the egg? 

The egg has existed on Earth for at least several hundred million years, 
while the Hen has been here only fifty million years. 

On the other hand, proteins may have evolved prior to DNA molecules. 
If you think of the nucleus as the embryo or egg, and proteins as its 
protecting membrane, or material body, then one may conclude that 
the chicken did, in fact, come before the egg.
