James, why are you running? This is not dodgeball. I gave you a specific molecular system with defined functional requirements and asked you to explain its origin through unguided, stepwise processes. You called it “impressive” and changed the subject. That pivot is noted.

Lenski does not answer the question I asked. Lenski showed adaptation within an already living, already replicating, already information-processing bacterial cell. That is not trivial, but it is not the same as showing that unguided chemistry can generate a coded, self-replicating, feedback-controlled molecular system from nonliving matter. You keep asking the question, “Can bacteria adapt?” and then claiming victory over the question, “Can unguided processes explain the origin of life’s machinery?” Those are not the same questions.

The same problem appears in your use of directed examples. When you appeal to laboratory work, selection experiments, or breeding analogies, you are pointing to cases where intelligence structures the conditions, defines the target, and filters the outcomes. That does not establish an undirected origin. It assumes what must be proved. Pointing to directed selection as support for undirected origins is not an answer. It is circular.

You also keep imposing an asymmetrical burden. You demand that I prove the designer exists, prove the designer can act, and prove the designer acted here before design can even be considered. But you do not apply that rule to your own position. You have not shown that unguided chemistry is causally adequate to produce coded, self-replicating, functionally integrated molecular systems. You believe it is. You expect future work to support it, in other words, you are standing on a hope and a prayer lol. But you have not demonstrated it. So your position rests on confidence in a cause whose full sufficiency is still unshown, while dismissing another cause class before the evaluation begins.

That is exactly what DB-FEP refuses to do. DB-FEP does not lower standards. It applies one standard to every cause class, that is, causal adequacy. Can this type of cause produce this type of effect? Unguided mechanisms are tested by that standard. Intelligent causes are tested by that standard. No cause class gets a free pass. No cause class is ruled out in advance.

Now, back to what you still did not answer.

I described the E. coli chemotaxis pathway in molecular detail. I identified the integral feedback architecture as central to its robust adaptation. The system depends on a specific activity-dependent asymmetry; the CheR preferentially acts on inactive receptors, and CheB-P preferentially acts on active receptors. That asymmetry is not decorative. It is part of what makes precise adaptation possible.

So here is the question again. Can you explain the origin of that molecular integral feedback controller through a series of unguided mutations, where each step is independently functional and selectively advantageous?

Not “evolution is a work in progress.”

Not “science uses partial models.”

Not “design is wizardry.”

Explain that controller. If you can, I will engage your explanation on its merits. If you cannot, then the point stands. You are defending the sufficiency of a mechanism you cannot demonstrate against an alternative you refuse to evaluate.

That is not a complete explanation. That is a commitment. That is your faith.
