But it will not, so long as that eye does not function.
Yes it will.
No, it won't. Break down the preliminary stages, and you'll see it won't. The alleged "light-sensitive" area, putatively eventually to end up being an eye, is at first barely light-sensitive at all. Its sensitivity is utterly uninterpretable to the rudimentary organism that has it, and it amounts to little more than a sunburn spot would. It presents no survival advantage, because it does not convey any survival-relevant and interpretable information to the organism. And in that state it must remain for thousands or millions of years, while the alleged slow-grinding of evolution works its way forward. In fact, the organism which has its survival attention divided between, say, its sensitive spot and its other survival faculties is not at an advantage but at a disadvantage.
The case becomes even more clear in the case of something like the bacterial flagellum. There's not only no utility to an undeveloped flagellum -- it's most definitely an injury, a survival-liability that, according to survival of the fittest, ought to result in the immediate death of the organism. But the Evolutionists' story requires us to think that not only did the injured organism persist, contrary to survival of the fittest, but that the injury was selected-for for millions of years; and not just in one organism, but in millions of others.
So the story eats itself. If survival of the fittest is true, then linearly-developing organisms cannot develop unless the mutation represents
a decisive survival advantage at every requisite stage. The second it does not, survival of the fittest kills the organism.

These guys know more about it than you or I
So "appeal to authority"?
I don't think they do. I think they're ideologically motivated.

Then as someone qualified to judge an article on Thomas Kuhn, you will appreciate that from outside your creationist bubble, it just looks like an archaic paradigm and the centuries of apologetics is analogous to the "normal science" Kuhn noted, which in evolutionary science is ongoing. Very few people think evolution is in crisis and that revolution is imminent.
Very few people thought the failure of Aristotelian cosmology was immanent. But it was. Aristotelianism, as you note from Kuhn's account and others, had become a sclerotic orthodoxy that was stifling cosmology, just as Aristotelian assumptions had once stifled medicine, too...and for thousands of years.
What if, as Thomas Nagel asserts, Evolutionism is just another sclerotic orthodoxy that's stifling science? I think he's right, of course: but even from a secular perspective, which is Nagel's perspective, there's a powerful case to be made that that is exactly what Evolutionism has become. We're failing to understand humanity -- its meaning, origin, morals, teleology and all of that -- because we're addicted to the paradgim that lets us reject God. And we're afraid to question it now, because man does not want God back in the equation...not because it's actually the right science, or the truth.

Personal Knowledge? It's well worth it.

Lots. He's very good at showing how our real understanding of science is formed. It's formed on a kind of faith, actually.
He uses the example of a bicycle, at one point: how many people who actually ride bicycles ever know that they are utilizing a series of falling motions mitigated by the curvature of a circle, thus generating gyroscopic stability as they produce a series of such motions? Most of us think of pedaling and steering, not of falling along curves. But we still ride bicycles, and imagine we know very well what we're doing. We're not conscious that what we are "knowing" about cycling is actually all tacit and pragmatic, not explicit and theorized correctly.
There's much more in him, of course. But that's an interesting snippet to me. So much of science is a kind of "practice" into which we are "initiated," not something we fully understand. It's not fully theorized before we do it.
For example, I'll warrant that we didn't learn science by understanding what science was. Rather, somebody in a lab coat, maybe a public school teacher reputed to be a science expert, told us to believe in it, and made us to rudimentary "experiments" until we came to believe in the experimental method. Then he maybe started teaching us some theory; but by then, we'd already been "apprenticed" into belief in what we were doing. So we didn't come as rational critics to the project: we came as naive children to an adult, and put our faith in his priestly knowledge, and only afterward found any confirmation of what he was saying.
We weren't wrong to trust him, perhaps. But we might have been, given the looseness of our actual method. And what he told us was very probably only half true. When he told us about the scientific method, perhaps, he was right; but if he, like scientists of old, had introduced us to phrenology or astrology...or to Aristotelian cosmology...we would have been powerless against his priestly authority. For we were only ignorant children, at the time; and we had faith in him that the facts really couldn't justify. He was an adult, but only a public school science dabbbler, not a true scientist, and not an expert, in most cases.
The upshot is that our introduction to science was not as we would like to tell ourselves, the mature exercise of advanced critical thinking, but rather a child's faith in an adult. And I'll warrant that was true not just for you and me, but for almost everybody who today calls themselves a scientist.
Very interesting how things actually happen.
