462 million-year-old fossilized eyes and brains uncovered in 'secret' Welsh fossil site

Preservation of fossilized brains is exceptional. Fossilized eyes are not. The trilobites all had very exceptionally preserved eyes. With lenses made of perfect C-axis crystallographically oriented calcite that precluded the double vision that calcite produces. Nothing in the fossil record even comes close to that remarkable evolutionary event back in the early Paleozoic. Even those fossilized brains are preserved as mineral, not as organic matter.

There is more to eyes than just the lenses. If brains are preserved then perhaps delicate structures within the eyes are as well! It could tell scientists about evolutionary relationships for one thing.
 
Delicate organic structures and chemical changes in the calcite lens compositions have already been documented in trilobites. Each lens is a single crystal with highly preferred C-axis orientation covered by a thin cornea. In modern arthropods like isopods the calcite crystals are random. Not sure about brain preservations.

You know, I find it interesting that the preferred theory of evolution is always thrown out there as a catch-all. I mean, if one would really seriously mull it over, why did all of these creatures supposedly evolve from others? Intelligent design would probably be a more accurate theory if one would call it that. The supposed fossil records would be impossible to connect as far as one species to another. The plausibility of life forms going from single cell to multicell to land foragers and then back to Sea living foragers. And somehow, plant life evolved from this same process is mathematically in calculable! If, it was that easy, why hasn't the scientific community been able to reproduce even rudimentary evolutionary processes? And, since evolution would take the path of least resistance, how or why would reproduction evolve from mitosis to meiosis? Meiosis is light years more complicated than mitosis. What would the process be? It's easy to throw out suppositions, one could expound on all of these theoretic ideas or opinions that would come to their mind, but there are no logical arguments or consequential evidence to produce an absolute scientific path to prove said process rather than just alluding to it!
 
The fossil record (especially that in the flat-lying rocks of the Grand Canyon) are undeniable proof of biological evolution. What concerns you are the mechanisms. An entirely different problem and discussion. It's worth adding that the evolution of both the higher animals and higher plants required two new amino acids not in the 20 of the genetic code. And remarkably the exact same four enzyme cofactors. This just adds to the mystery of the mechanisms, but does not detract from the fossil evidence.

It's not impossible. Paleontologists do it regularly.

Why? Plant and animal cells have many similarities due to sharing a (very) distant common ancestor. No sexual reproduction at the time though so any evolving that happened had to rely on mutations.

It has. Drug resistant bacteria springs to mind. Or this: https://news.harvard.edu/gazette/story/2014/02/evolution-in-real-time/

There's nothing inherently intelligent about how life works. One has only to look at the human eye (and many other body parts) to see that if there's a designer behind it then intelligent it is not!
