Question for Evolutionists: Is the cockroach a highly evolved creature?

I like the bug that blows up its head like a balloon... looks designed to me...
I propose a definition for "highly evolved".......
A species in which the rate of change of allele frequency approaches zero over 100 generations.
Btw, I'm flexible on the number of generations.

It looks like a vacuum cleaner bag got sick of eating dirt and decided to live on it's own.Tardigrads are the "highest" evolved animal. It can be without water for 10 years. Can survive in space. One of the only species that have gone through several mass extinction events in Earth's history. They're the ones with the best track record.
Cute little thingy, isn't it.

Sounds about right.
I think the Jewel Wasp is more interesting, from an evolutionary/creationist point of view.
"The secret to the Jewel Wasp’s ‘captivating’ abilities lies in a neurotransmitter called octopamine in the cockroach’s brain that contols its movements. The wasp’s venom blocks the octopamine, literally converting the cockroach into a zombie. This ‘zombie’ cockroach is completely unable to fight back as it is pulled by the wasp into its underground lair. If you’re wondering why the wasp would go through all this trouble to just eat a cockroach, here’s the really weird part – the cockroach is meant to unwillingly play the part of surrogate mother. The wasp lays an egg into the cockroach’s abdomen, and the larva later hatches and eats the live cockroach from inside out. It takes 3 or 4 days for the larva to hatch, after which it slowly feeds on the roach’s internal organs, keeping it alive the whole time. This process takes about 7-8 days, during which the meat needs to be fresh for the larva. And because a dead cockroach rots within a day, the wasp prefers the ‘stun’ method. Once the roach is eaten up completely and it dies, the larva forms a cocoon inside it. A fully-grown wasp emerges from the cockroach carcass a month later."

The ones who agree that it's highly evolved are making a big mistake as they make limits
for evolution and contradicting themselves.
Many organisms were fit to their environment and evolved to other kind otherwise why the fish
moved to the land and evolved to other forms of creatures.

In science & engineering, one often encounters limits.
Regarding evolution, as an organism evolves to adapt to its environment,
the rate of change of allele frequency approaches the limit of zero.
The existence of such a limit isn't a problem.

I'm not sure I understand what you're saying. Are you saying that there are less genetic changes or diversity when an organism is more adapted to an environment? I'm probably misunderstanding you. The coffee is still making it's way to my brain here.
Just to add an FYI, you might know this already, but for anyone who doesn't. Even in species that have reached a maximum in a specific environment (like the shark), the genetic diversity is actually very high. The genes that make sharks to be "sharks" stay the same, but there's a lot of other genes that still changes and apparently, in such cases (even like human) the diversity is even greater than for a species under selective pressure.
I suspect that in the case of cockroach, they're also at a maximum, and because of it, they have such a diversity of genetic material and that's why they can adapt so rapidly to toxins and such. There's a greater chance that there are cockroach families with genes that are close or perfect for their resistance already, before they even are exposed. Just some thoughts.

No limits for evolution, dude
it's an ongoing process, do you expect humans of today will be the same if they were
able to live some millions of years a head.

The rate of genetic changes approaches zero.
I did know that.
I gave an example of it (albeit without explicitly stating that aspect) of cichlids.
Viewing evolution as a stochastic system, it's reasonable to assume that physical laws impose limits.
I expect humans to change.
But I make no predictions how.

When? When they're reached a maximum?
Do you have a link to some research showing this?
I don't view it in terms of maximum of something.
It's about adapting to the point that allele frequencies are stable, ie, optimized for the organism in its environment.
No.
it's all my speculation & opining.

The allele frequency will only stabilize for the genes responsible for the beneficial traits, not for traits that are discardable.
It's like eye color in humans. There's at least 3 different genes responsible for eye colors, and there's more than 120 alleles in one of them. Traits where you don't have selective pressure, you get a higher allele frequency, if I recall my anthropology right. You increase the genetic pool, so to speak, in the areas where it doesn't matter.
Also, what I mean with "maximized" is the same as "optimized for the organism in its environment." It's important to remember though that not all traits are necessary or important for the survival of a species.
Fair enough. I take that as a valid answer and reason as any.
Such complexity is why I stress that change approaches zero.
(I take into account that there is much I don't know about this field I make guesses about.)

Sure. I agree that the phenotype changes approaches zero, but the genotype doesn't. I'm quite sure about this from my studies, but I'm not going to force you into my opinions. I respect you and your opinions waaay too much to do that.
Keep opining.....it illuminates things for me.Sure. I agree that the phenotype changes approaches zero, but the genotype doesn't. I'm quite sure about this from my studies, but I'm not going to force you into my opinions. I respect you and your opinions waaay too much to do that.

The cockroach is exactly what God intended it to be when He created it. If He meant for it to change or evolve then it has, if not then it has not. I hope that helps.
Then he meant them to flock to the apartments of me worst tenants!
