Wether they have a completely different 'blueprint'' than DNA is irrelevant, if there is a form of mutation + nat selection, it will favor the early eye.

Just wanted to point out that the analogy to a blueprint is a very bad analogy. A blueprint is basically a map that shows where everything goes. This is not true of DNA and also wouldn't allow for mutations. A better analogy is a 'recipe.' A recipe doesn't show you where things go, it just tells you how much of what. This is subject to mutations, such as adding too much flour, or too little baking soda, which will ultimately affect the end product. Blueprint also sorta implies design, as opposed to recipe which is slightly more neutral.

Merely a suggestion. I think 'blueprint' is misleading.
