Here's a paper on the molecular phylogeny of some clock genes in prokaryotes.

I was reading through the study you linked to and came across this section:

Although the kai genes are under comprehensive study with regard to the mechanism of action, their evolution has yet to be resolved completely. The kaiC gene has a double-domain structure, and each of the domains has an ATP/GTP-binding site, or Walker's motif (2, 11). Based on its structure and sequence homology, the kaiC genes were classified as a family related to the RecA gene family of ATP-dependent recombinases (12). In addition to the kaiC genes with the typical double-domain structure, there are many single-domain homologous genes in Archaea and Proteobacteria. It was assumed that an ancestral single-domain kaiC gene was horizontally transferred from Bacteria to Archaea and then the double-domain kaiC evolved through duplication and subsequent fusion in Archaea (12). Although the evolution of the kaiC genes has been hypothesized, no data or hypotheses are available regarding the evolution of two other circadian clock genes, kaiA and kaiB. The evidence about the key role of kaiC in cyanobacterial clock regulation (9, 11), along with its homology to archaeal RecA genes, suggests that this gene is evolutionarily the oldest among the three.

Ping us when they get it figured out. Not only are they still trying to show how it evolved; they are still studying the mechanisms and how they work.

Fascinating, don't you think? How did they evolve? Did they evolve? How do they work? How do they filter out the noise from the valuable information?

Perhaps we'll never know.

Ping us when they get it figured out.

Your misreading of the paper notwithstanding, they've already figured out a lot of it, far more than the vast majority of anti-evolutionists will ever know or grasp.

Ping us when you get God's exact construction methods figured out to anywhere near the kind of detail that the biologists have already achieved.

"How do they filter out the noise from the valuable information?"

Noise doesn't work. If a mutation results generation of noise, it lowers the signal to noise ratio. If it's lowered to far, the organism fails to persist. The original organism continues on.

"Not only are they still trying to show how it evolved; they are still studying the mechanisms and how they work."

This can always be said about something, or other. What's important to note is what is known now and also, to compare it to the state of affairs in knowledge and understanding that existed before.

"Fascinating, don't you think? How did they evolve? Did they evolve? How do they work?"

Subtle. Lack of knowledge and understanding does not negate what is known and understood. In fact, what is known and understood is used to increase the content of that set and reduce the content of the set of unknowns.

You can, of course, hope, but I wouldn't bet that way.
