Nilsson and Pelger's paper was 28 years ago. More has been found since then.

Maybe, but it was an influential paper. The link you gave also quotes and uses N+P research.
Unlike theists, scientists are not satisfied with a dogma but keep on digging. Here is some updated information:
The link you supplied starts off by saying,
I will present some concepts about some of the major steps in the evolutionary process to stimulate your thinking about this interesting and complex topic.
I was hoping your link would provide evidence for eye evolution, as opposed to provoking thoughts on the subject. As is often the case, papers on evolution are full of words and phrases like, murky evidence, could have, it suggests that, probably, possibly, etc. This is not surprising when the soft tissue fossils are 500 - billions of years old. A lot of guess work is needed to fill the gaps.

Multiple light-sensing cells in an eyespot in a multicellular animal, such as a leech could recognize only light or dark. Perhaps after 35 000 generations, an organism discovered that developing a concave cup instead of a spot produced a more successful and competitive organ for sight.12
As Nilsson and Pelger12 suggested, from an eyespot to an eyecup to a fully formed camera-style eye could take as few as 364 000 generations, and the production of such an eye in perhaps as short a period as half a million years. Of course, there would be more to an eye than just a cup, but that is a key step (Figure 2), and that cup may fit the real definition of an ‘eye.’
If you study the Nilsson Pelger paper closely, they have shown 7 sets of parameters for the eye lens to develop. These amount to 7 goals, and without these 7 goals, the N+P paper crumbles. Yet one of the main principles of evolution, is there are no goals that life works towards. Presumably single cell life existed without eyes, so eyes were not needed. I am not disputing that eyes are an advantage, but they weren't needed in single cell life.
Your link provoked the thought that life could not evolve without a creator God guiding the process. Darwin probably knew that real evidence for the evolution of the eye would be almost impossible to prove.
There is extensive work that shows that the eye not only evolved, but it evolved multiple times. The human eye did not suddenly arrive, with all these presumed "goals". Eyes started with small photosensitive indents and things progressed from there.
Agreed, there is fossil evidence to show variations in diverse species, many still exist today. But in centuries from now, I don't believe the ToE will stand the test of time.
