-----open and close in a precise order. It performs a series of steps that can best be described, based on the latest research, as follows:
[1] TOPOISOMERASE II OPERATION
Replication or transcription of DNA stresses the macromolecule, resulting in supercoiling. Topoisomerase II relieves the stress by reducing the number of supercoils. The enzyme is composed of two identical halves that combine to form three gates that
1. One DNA segment enters the upper gate and then binds to the middle gate. A second strand enters the top gate. The middle and lower gates are initially closed.
2. The middle gate cuts the first strand in two. Two ATP molecules attach to the upper gate, and the gate closes.
3. One of the ATP molecules breaks apart releasing energy that might help keep the upper gate together for the next steps.
4. The middle gate separates the two ends of the first DNA segment, creating a gap. Both DNA ends remain attached to the middle gate.
5. The second DNA segment moves through the gap.
6. The upper gate rotates. The middle gate closes, and the two DNA ends are reconnected.
7. The enzyme breaks apart the remaining ATP molecule, and the lower gate opens, allowing the second DNA segment to leave.
8. The lower gate closes, and the upper gate opens, releasing the first DNA segment.
After the last step, the topoisomerase is reset and ready to perform the same process again.

"Does topoisomerase do anything useful for the organism?" Or more precisely, "Topoisomerase II precursors" (which may be other forms of topoisomerase). This is a key point of contention with IC, which I know has been done to death. My argument does notdepend on there being no potential precursors, but rather is questioning what is needed for "molecular macroevolution" (if I can use that term) or exaptation to form Topoisomerase II.
That is, even just largely co-opting pre-evolved components still requires precision integration, expansion, function tuning, etc. This would be a multistep process requiring positive selection pressure for each intermediate. Now, arguably this is notimpossible in principle: each intermediate might permit a slightly higher survival rate, but this seems very unlikely to be sustainable over the stepwise addition of whatever portion of the total 765 amino acids need to be discovered.
A related question here is, what minimum degree of gradualism is required for evolution to work? To what extent must the pathway fitness be monotonically increasing?

My question to you is, why the rage and vitriol?You're "correction" is still loaded is falsehoods. We're not talking about incorrect
deductions. We're talking about asserting false premises. It's bullshit.
It makes it evident that you have almost no understanding of even the terms "phenotype", "selections", and as such no understanding of evolution.
Imagine you are an auto mechanic, somebody drops off their car for repair and
you fix it. The car's computer had thrown some codes about about misfiring and
problems with certain voltage on some fuel injectors. You know your stuff so you strip off the plenum and get to the injectors, you take out your handy volt-ohm
meter and check the resistance across the indicated injector and it is a dead short.
You call up the customer and ask if they want you to go ahead and replace all of
the injectors while you are there as the car has over 90K miles and it will save
them a lot of money if you do them all now rather than have to do the tear down
again for one that will quite likely fail in the next 10-15K miles.
He gets upset and tells you you don't know what you're doing, you just need to
clear the computer code so you could pass your state inspection. It was a computer
problem, the engine was running fine. Sure, running fine with a fuel injector that
was shorted out.
The guy doesn't understand cars but he's telling you what the problem is.
The point is, you aren't seeing rage and vitriol. You are seeing exasperation.
You don't even understand a simple thing like selection and you are here evangelizing
about how evolution could not have produced X, Y, or Z.
Find an on-line course on population genetics. Take it. There will be math, and
lots of it. Not that you're ready for it, but you'll understand some of it. More significantly,

The above presses a gross misconception: that phenotype means "observable

"phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment."
Not sure what Daggett's objection is here.That's a rotten definition, especially when you want to apply it scientifically.
It's rotten because so many will misunderstand "observable" to mean something
that you visually detect. If one has a more scientific notion of "observable" to
mean has a measurable effect, it's closer. A phenotype is a tangible consequence
of a genotype. It can be cryptic. A phenotype can produce improved resistance
to cold/heat, which won't be revealed outside of cold/hot conditions.
Regardless, it's clear MarkE was inclined to dismiss 'invisible' intracellular changes
as not being phenotype changes, which he thought couldn't be acted upon by natural selection.

you fix it. The car's computer had thrown some codes about about misfiring and
problems with certain voltage on some fuel injectors. You know your stuff so
you strip off the plenum and get to the injectors, you take out your handy volt-ohm

them a lot of money if you do them all now rather than have to do the tear down
again for one that will quite likely fail in the next 10-15K miles.

Not so. I accepted the correction that these are indeed phenotype
changes (e.g. lactose metabolism in bacteria). But my argument is that substantial intracellular changes (what might be called "molecular macroevolution") may be less accessible to NS. For example, the
development of the camera-style eyes of vertebrates requires gradual refinement over many steps with positive selection pressure applied.

it wasn't accessible to natural selection. You're now claiming an
absence of functional intermediates, which is not the same thing. "Accessible to natural selection" and "accessible by natural selection"
may be only a small change in sequence, but it's a large change in semantics.
Anyway, creationists have long claimed that eyes are unevolvable due to
a putative lack of intermediates. Why should we take your claim about topoisomerases more seriously that their claims about eyes? Picking a
darker crevice (topoisomerases evolved longer ago, so more of the
evidence has been erased by time) for your gap doesn't make the argument better.

Except that you have not shown that it's a problem. Topoisomerase is an enzyme. Mutations in enzymes change their activity. What's problematic
about mutations gradually improving the activity of topoisomerase?
Given a choice between a barely active proto-topoisomerase and one that
is slightly more active, why couldn't natural selection select for the slightly more active one? You (or, more likely, your sources) are
inventing a problem that is not there.

Human topoisomerase, for example, contains 765 amino acids. Topoisomerase II gathers, clamps, snips, swaps, and rejoins DNA strands [1]. That is, it has very high information content (765 units) and functional complexity and specificity.

My question for you is, is that level of ignorance a proper foundation from

effect basic, internal cellular functions, like DNA replication, or
transcription, or formation of chromatin, are somehow less accessible
to natural selection than genes that effect things like body mass, or
coloration, or beak shape. Any mutation that effects fitness in any
way, no matter where that effect occurs in the organism, is accessible
to natural selection. And no matter where in the organism the effect
occurs, there is always a long chain of effects between the mutation
itself and whatever effect it has on fitness. There is nothing special
in that regard about mutations in topoisomerase genes.

The evolutionary pathway of an eye can be conceived of as a long series
of small variations each producing *functional* intermediates. But this
is much more difficult with the evolution of Topoisomerase II. Most
intermediates will be *non-functional* in terms of *progression towards
Topoisomerase II function*. That's the problem.
progression to topoisomerase II function? That function requires various enzymatic activities, various specific bindings. Why can't changes in the amino acid sequence (and hence the 3-d structure) lead
to slightly better substrate binding, slightly increased enzymatic activity, etc? How is this different than gradual refinement of any
biological activity?
he's found in creationist publications. It's probably a waste of time
arfuing with him. So far the specific point is concerned we *know* from
Steve Benner's work (on ribonuclease, for example) that the catalytic
activity of ancestral forms can be measured.

Regardless of Steve Benner's work (on ribonuclease, for example).The evolutionary pathway of an eye can be conceived of as a long series of small variations each producing *functional* intermediates. But this is much more difficult with the evolution of Topoisomerase II. Most intermediates will be *non-
proto-topoisomerase and one that is slightly more active, why couldn't natural selection select for the slightly more active one? You (or, more likely, your sources) are inventing a problem that is not there.That's the problem.Except that you have not shown that it's a problem. Topoisomerase is an enzyme. Mutations in enzymes change their activity. What's problematic about mutations gradually improving the activity of topoisomerase? Given a choice between a barely active
ligation, and release).The enzymatic activity here is not simple catalysis that lends itself to gradual improvements and reaction efficiency.
In this case, it's the action of a molecular machine that is complex (765 amino acids) and specialised (it catalyses changes in DNA topology by passing one double-stranded DNA segment through another, which includes strand capture, cleavage, swapping,
There are lots of big enzymes and enzyme complexes which catalyze multi-step processes. Why do you think topoisomerase is special?coordination).
Even if some subunits are preexisting, an evolutionary process would be required to integrate each subunit and control the new function (e.g. alterations to existing polymers to adapt them to the new ensemble, and additional amino acids to provide
text on the way to get enough background that the papers on topoisomerase evolution would make sense to you.I guess this comes down to familiar questions of a plausible gradual pathway and avoidance of irreducible complexity (the latter being a subset of the former?).Sure. And if you were interested, you could go to Google Scholar and search on evolution of topoisomerases (and gyrases) and try to figure out what is already known in terms of possible intermediates, etc. You might have to stop by a molecular biology
The much bigger question is why are you wasting your time with this stuff? It is beyond obvious that your main interest in any of this, OoL or topoisomerase evolution is to say "look, science has no explanation for this, therefore there is a (supernatural) designer." But that sort of argument is useless both scientifically and theologically.
Supernatural ID is useless scientifically because it leads nowhere. All it does is say - "If you've been trying to understand something for X amount of time and have had Y amount of resources available to you, and you still don't have a definitiveanswer, give up." Supernatural ID provides no details and is supported by no direct evidence - indeed you say yourself that it would be a category error to ask such things of supernatural ID. So it gets you nowhere in terms of understanding the what
More importantly, supernatural ID is useless theologically. Remember your favorite Dawkins quote about how the universe looks like it has nothing but blind, pitiless indifference to anything we care about. Well, here are two potential rebuttals.prosper. The race does not go to the swift. But, the indifference is an illusion. God is not indifferent to human suffering, indeed He became a human and suffered terribly and unjustly. He knows what you are going through, and He says "Have faith. Love
1. More or less mainstream Christian rebuttal: Yes, the universe can look pitiless and indifferent to human suffering, especially the suffering of the innocent. Children die of cancer, good, generous people die in natural disasters while the wicked
2. Supernatural ID rebuttal: Yes, the universe looks pitiless and indifferent. But it also contains a lot of complicated stuff in it that could not have occurred naturally - finely tuned constants of nature, the origin of life, multi-step enzymeprocesses, bacterial flagella, metazoan body plans. So there must be an intelligent designer behind it all. We cannot draw any conclusions about the designer apart from the things he designed. So we know that the designer designed a universe that acts
Supernatural ID does not get you to the sort of God you want to believe in - an invisible, omnipotent, personal loving God who cares for you and everybody else and offers you eternal life and the chance to reconnect with all your loved ones who havedied as long as you sincerely believe. For that you need a leap of faith. And that leap of faith is no bigger or smaller depending on whether you are satisfied with progress in OoL research or topoisomerase evolution.
If you want to understand evolutionary biology and molecular biology and genetics, you need to go take some courses or at least work through a few textbooks. If you want to work on Rebuttal #1, though, you can skip right over anything having to do withscience as totally irrelevant. Nobody accepts Jesus Christ as their personal Lord and Savior because he offers a better explanation of the OoL than David Deamer. And a fully worked out empirically supported naturalistic explanation for the OoL would not
