Lot's sound and fury, but no answer. You walk backwards from the present. Start at the beginning, and explain why any organism would retain a protein with no apparent purpose? Or, did all of the proteins in the eel appear all at once. The reality is, there is no explanation for retention of a single protein, much less 5 or 7 or 13. There is no purpose in them...there is no rationale for retention. And there is no rationale why these apparently random proteins would be begin to work in harmony with one another.
BTW - your reference to my, what was it, "regurgitating" creationist talking points - did you think all of the information you posted? Or, were you dependent upon the research of someone else? We all cite our "experts" as justification for the positions we take. I happen to think that my "experts" are right, and more logical than yours.
