Apparently the setup is this: Researchers come up with EV, claiming
it simulates evolution in nature. They also claim EV is a 'blind,
unguided' search.
This paper argues that actually EV is a targeted search.
Assume this paper is correct. Here's my question: Do we now therefore
have evidence that evolution in nature is in fact a targeted search?

nullasalus,
You have no idea what ev does, do you? Maybe you should read a brief description of the program on Tom Schneider's site. Perhaps you will find something like this:
The organisms are subjected to rounds of selection and
mutation. First, the number of mistakes made by each organism in the
population is determined. Then the half of the population making the
least mistakes is allowed to replicate by having their genomes replace
(`kill') the ones making more mistakes. (To preserve diversity, no
replacement takes place if they are equal.) At every generation, each
organism is subjected to one random point mutation in which the original
base is obtained 1/4 of the time. For comparison, HIV-1 reverse
transcriptase makes about one error every 2000-5000 bases incorporated,
only 10 fold lower than this simulation [17].
From this passage, one may reasonably conclude that the evolutionary
process modeled by ev has two parts: (1) random, unguided mutations and
(2) non-random, guided selection. It is a targeted search in the sense
that there is a fixed genetic sequence with the best chance of survival
and digital organisms invariably converge to that sequence when the
program is run.
Note that Schneider wrote this in 2001. If it took 9 years to realize that ev is a targeted search, boy, are they slow!
Or maybe the local fan base has yet to figure out what Dembski and
company are saying in their paper. Keep up the good work, boys!
EV was detected as a bogus example for "evolution" when it was first presented as such an example.
That it was just recently put in a peer-reviewed paper- what has been
known for some time- is not any indication of when it was known.
Also from the way EV actually is written it is reasonable to conclude
that all reproduced sequences are matched against a TARGET and then
selected. IOW there is a fixed sequence- a target- that the mutated
sequences are trying to match. The better the match the better the
chance of survival and reproduction.
Also from the way EV actually is written it is
reasonable to conclude that all reproduced sequences are matched against
a TARGET and then selected. IOW there is a fixed sequence- a target-
that the mutated sequences are trying to match. The better the match the
better the chance of survival and reproduction.
You had no idea what question I was even asking, did you? Let me ask
it in another way, nice and slow, so even you can grok it.
From the paper:
Schneider [16] claims that ev demonstrates that naturally
occurring genetic systems gain information by evolutionary processes
and that “information gain can occur by punctuated equilibrium”. Our
results show that, contrary to these claims, ev does not demonstrate
“that biological information…can rapidly appear in genetic control
systems subjected to replication, mutation, and selection” [16]. We show
this by demonstrating that there are at least five sources of active
information in ev.21
…
Our analysis highlights the importance of disclosing
sources of knowledge in computer searches when measuring the ability of
search mechanisms to generate novel information. As far as ev can be
viewed as a model for biological processes in nature, it provides little
evidence for the ability of a Darwinian search to generate new
information. Rather, it demonstrates that pre-existing sources of
information can be re-used and exploited, with vary-ing degrees of
efficiency, by a suitably designed search process, biased computation
structure, and tuned parameter set. This con-frms that the conservation
of information principle, as manifest in the No Free Lunch Theorems, is
“very useful, especially in light of some of the sometimes-outrageous
claims that had been made of specifc optimization algorithms” [4].
So, let's assume Dembski and company are right in their paper. Does
this mean that ev, insofar as it is offered as a model of nature, is in
fact an ID model? To be even more specific, would Dembski and company –
or other ID proponents – make this claim?

O, I'm well aware what you stated, nullasalus. Here:
Apparently the setup is this: Researchers come up with
EV, claiming it simulates evolution in nature. They also claim EV is a
'blind, unguided' search.
This paper argues that actually EV is a targeted search.
Everyone who paid the slightest amount of attention to this knew all
along that ev was a targeted search. You're tilting at windmills.
And pray tell, what is "a 'blind, unguided' search?" Enquiring minds want to know.
olegt:

So all those people have been lying for 9 years? At least Dawkins was
honest enough to come right out and said his "weasel" program, also a
targeted search, is not indicative of biological evolution.
Everyone who paid the slightest amount of attention to
this knew all along that ev was a targeted search. You're tilting at
windmills.
Spectacular. Gonna answer my question then? Why, it oughta be easy!
So, let's assume Dembski and company are right in their paper.
Does this mean that ev, insofar as it is offered as a model of nature,
is in fact an ID model?
And pray tell, what is "a 'blind, unguided' search?" Enquiring minds want to know.
Dembski, Marks and company claim: ev is an evolutionary search
algorithm proposed to simulate biological evolution. As such,
researchers have claimed that it demonstrates that a blind, unguided
search is able to generate new information.
So, what are you saying here olegt? That no researchers claim claim
that evolution is "blind" or "unguided" in any sense relevant to this
paper? That they do, but they're full of crap and speaking nonsense? Or
maybe you're saying that evolution is guided and the arrival of various
species, humans included, was downright inevitable?
olegt the TE. I could enjoy that.

Defend your position or admit that it was silly.
If you wish to do the former then define what "a 'blind, unguided'
search" means and provide some quotes from scientists on the
evolutionary side.
Wow. Even if I do the internet equivalent of speaking really slowly
and spelling out my question in a laborious manner, you still don't grok
it. Do you learn by a Clockwork Orange method or something?
I don't need to spell out what a "blind, unguided search" is – the
very act of considering nature as operating according to an algorithm or
as having intrinsic information is enough for me. Though I do like your
routine here of "What you said is wrong! Now, tell me what you meant
because I don't get it."
Comment by nullasalus — December 18, 2010 @ 8:58 pm
Which evolutionary biologist characterized ev as "a 'blind, unguided' search?" Name names, nullasalus!
Wait a sec. You think ev, which was meant to model evolution, was NOT
"blind" or "unguided"? You think a model of evolution as a foresighted,
guided process is accurate?
Olegt, ARE you a TE?
Comment by nullasalus — December 18, 2010 @ 9:22 pm
I explained my understanding of ev here. It has a random component (mutations) and a non-random one (selection of a pre-specified target). Tell us what you mean by "a 'blind, unguided' search." I have asked you, like, a bazillion times and you have been unable to explain.
Natural selection is that blind, unguided "search". No targets allowed.
Maybe you need nullasalus to post that. nullasalus you have my
permission to tell olegt that natural selection is a blind, undirected
"search" and that no targets are allowed with NS.
The Ev program clearly and unequivocally demonstrates
that no intelligence is required for information (Rsequence) to appear
in biological systems, so this definition collapses.
He aslo sez:
Apparently they have not studied Ev enough to understand
that it is the simplest possible model that shows how information is
gained in living things.
IOW information is gained in living things via an intelligently designed targeted search.
Schneider is an IDist!
But wait- what else does he say:
That simple computer program generated information by Darwinian evolution – no intelligence was required.
Geez that page is full of Schneider blushing about EV…
Well, we've gone back and forth enough times. Let's review.
Apparently the setup is this: Researchers come up with
EV, claiming it simulates evolution in nature. They also claim EV is a
'blind, unguided' search.
This paper argues that actually EV is a targeted search.
The second paragraph is patently wrong. It is well known that ev has a fixed target that is known in advance. Schneider's 2001 description of the program explicitly mentions that.
The weight matrix gene for an organism is translated and
then every position of that organism's genome is evaluated by the
matrix. The organism can make two kinds of `mistakes'. The first is for
one of the γ binding locations to be missed (representing absence of
genetic control) and the second is for one of the G−γ non-binding
sites to be incorrectly recognized (representing wasteful binding of
the recognizer). For simplicity these mistakes are counted as
equivalent, since other schemes should give similar final results. The
validity of this black/white model of binding sites comes from Shannon's
channel capacity theorem, which allows for recognition with as few
errors as necessary for survival [1,16,7].
There is no need for "ID researchers" to prove that ev is a targeted search.
The first paragraph contains an ill-defined term 'blind, unguided' search. The meaning of this term remains obscure despite multiple inquiries directed at its creator.

You've asked those researchers and they didn't tell you? How rude!
So, olegt: Are you saying ev is a model of ID evolution? Still waiting on that one!

olegt:

Obviously there was as Schneider still insists EV is an example of
Darwinian evolution. So you will be notifying Schneider about his
misunderstanding. Thanks.
And natural selection is blind and unguided, if it is ill-defined that is your position's fault.
olegt
Which evolutionary biologists characterized ev as "a blind, unguided search?"
Again, Tom Schneider, the guy who wrote it, when he says that EV is an example of Darwinian evolution.
olegt:
And how do you understand that term?
As the professor of public understanding of science understands it.
He tells us that natural selection is blind and purposeless- it is just
splitting hairs unguided vs purposeless.
What's an ID model, kornbelt? I don't think ID has models. Maybe you should point me to a description of one or two.
ev is a model of evolution of a very simple system with a fixed fitness landscape. Nothing less and nothing more. Read Tom Schneider's paper, it is not that technical.
A targeted search is an ID model. And EV is a model of a targeted search.
Tom Schneider sed EV modeled classic Darwinian principles. So either
he is a liar or he is ignorant of classic Darwinian principles.
Now olegt sez "ev is a model of evolution"- well it ain't a model of
biological evolution as biological evolution does not posit targeted
searches. OTOH ID does posit targeted searches as a mechanism.
IOW olegt is either a liar of he is ignorant of classic Darwinian principles as well.
Either way it doesn't bode well for his credibility…
What you just did is tautological: ev is an ID model because ev is an ID model.
What you should do is point me to a description of an ID model that is described elsewhere, compare to to ev and then declare victory.
I am not holding my breath, though. One of the ID luminaries, who coauthored the paper we are discussing, wrote this once:
As for your example, I’m not going to take the bait.
You’re asking me to play a game: “Provide as much detail in terms of
possible causal mechanisms for your ID position as I do for my Darwinian
position.” ID is not a mechanistic theory, and it’s not ID’s task to
match your pathetic level of detail in telling mechanistic stories. If
ID is correct and an intelligence is responsible and indispensable for
certain structures, then it makes no sense to try to ape your method of
connecting the dots. True, there may be dots to be connected. But there
may also be fundamental discontinuities, and with IC systems that is
what ID is discovering.”
So, no, by very definition, ID does not do models. A designer can do
whatever he wants. Particularly if he is omnipotent. No point in trying
to model that.
Assuming Dembski et al are correct in their paper, does
this mean that ev, insofar as it is offered as a model of nature, is in
fact an ID model?
This is the kind of hypothetical question politicians avoid for good
reason because their answers will often be taken out of context and
become headline news.
Since I’m not running for office I’m not shy about agreeing that ev can be thought of as a model in support of ID Science.
The usual problem comes down to the definition of "intellegence".
If "intelligence" is the "ability to learn and adapt" then Natural
Selection provides life a kind of intelligence in a macro sense.
I happen to think there is additional "intelligent" coordination in life via quantum links.
However, evidence of intelligence does not automatically mean a purposeful designer is involved.
The omnipotency of the designer means that any model is an ID
model. So arguing whether this or that is an ID mechanism is pointless.
Any natural process could be faked by a skillful designer.
At the same time, ev is clearly a Darwinian model. It has all the
requisite ingredients: random variations, heritability, and selection.
It is a very simple model: e.g., it has a fixed fitness landscape with a
single minimum. So it cannot be used to understand coevolution. But
that's what models are for: they are simplified versions of reality.
True, there may be dots to be connected. But there may
also be fundamental discontinuities, and with IC systems that is what ID
is discovering.
Heh, heh. Discontinuities. Fundamental ones at that. Look at
conscious intelligent humans. Is that not a hallmark of design? Surely
you jest when claiming that intelligence cannot be physically manifest?
Since every process could have been designed, it makes no sense to ask whether or not ev is an ID process.
This is a bogus argument. Observe the beach goer. Moves small
mounds of sand when walking. Wind accomplishes the same. Was that sand
purposely shifted by those feet? Perhaps. But design would be
undetectable to an investigator. OTOH, a sandcastle is a different
kettle of fish. Design can be present but whether it is detectable is a
separate issue. That not all causal trails lead to design detection,
even where the omnipotent cause was present, makes a practical
distinction between omnipotence and evidence for design.
Bradford, but wouldn't you agree that any sand pattern could
have been created by a (human) designer? If you do then there is no
point in asking whether any particular sand pattern is designed unless
by that you mean to negate the possibility of its natural formation.
That, again, brings us to the point that ID is simply a negation of
Darwin's theory.
Olegt: Bradford, but wouldn't you agree that any sand
pattern could have been created by a (human) designer? If you do then

natural formation.
Not all sand patterns are attributed to design. A sandcastle is. A
wavy mound may or may not be designed. There is a design sifter at work
here.
As for the possibility that natural forces are insufficient to
generate an outcome, that should not be dismissed as an option by
rational minds. Discontinuity. Therein lies an indicator of
insufficiency.
TP is in an excellent position to conduct an experiment. Go to the
beach and move some sand around. I'll bet you can go to two locations
and leave unmistakable evidence of design behind at one and
undetectable, but purposeful, movement of sand at another.
This is a bogus argument. Observe the beach goer. Moves
small mounds of sand when walking. Wind accomplishes the same. Was that
sand purposely shifted by those feet? Perhaps. But design would be
undetectable to an investigator. OTOH, a sandcastle is a different
kettle of fish.
First of all, I suggest it is not bogus to request and example of something that is considered to NOT be designed.
For example, is the moon designed?
(BTW, there's a lunar eclipse tomorrow night)
We are dealing with hypotheticals here.
Promises of irrefutable Sand Castles and Irreducibly Complex
flagellums quickly become less than irrefutable and/or irreducible.
They become Mike Gene's rabbits and ducks. It is all in how you look at
them.
Olegt, you need to make a distinction between a theological tenet-
omnipotence- and design detection. The former posits a broad claim of
all the physical universe resulting from a singular causal source. The
latter makes a distinction among parts of the created universe. Some
provide evidence of a causal trail leading to an intelligent source by
virtue of their physical properties. Others can lead to that same
source only by imputing conceptual explanations that are extrinsic to
the physical reality of that which is observed.
olegt:
Bradford, but wouldn't you agree that any sand pattern could have been created by a (human) designer?
For the sake of argument (only) – That would be why we need POSITIVE
evidence for a designer's presence. (However I am not sure that any sand
pattern could have been created by a (human) designer- what about
patterns dated to before humans were supposed to be around?) IOW we
don't infer a designerdidit until BOTH conditions are met.
If you do then there is no point in asking whether any
particular sand pattern is designed unless by that you mean to negate
the possibility of its natural formation. That, again, brings us to the
point that ID is simply a negation of Darwin's theory.
Again with the ignorance- in order to reach any given design
inference one must not only eliminate aternatives (to some degree) but
there must also be POSITIVE evidence for a designers involvement.
No need to wax philosophical. The question was much simpler and more
specific: do you agree that pretty much any sand pattern (within
physical limits) could have been created by a human designer?
If you answer positively to that, would you further agree that by a
designed pattern you really mean one that could not have arisen through
natural means?
If you answer positively to that, would you further
agree that by a designed pattern you really mean one that could not have
arisen through natural means?
Through blind, unguided means and that matches some specification.
Part of science is determining how someting came to be the way it is…
Olegt: No need to wax philosophical. The question was
much simpler and more specific: do you agree that pretty much any sand
pattern (within physical limits) could have been created by a human
designer?
Could have been but some patterns lead one to suspect natural causes
i.e. storms. Physical features determine plausible conclusions.
If you answer positively to that, would you further agree
that by a designed pattern you really mean one that could not have
arisen through natural means?
That's one option- Dembski's discontinuity indicator. The other
comes from the Mike Gene school of thought which draws inferences of
teleology from the nature of a physical process.
kornbelt888, see this. Since every process could have
been designed, it makes no sense to ask whether or not ev is an ID
process.
It certainly makes sense to ask that question. I think you mean to
say that the answer is irrelevant with regards to Ev's significance. But
it isn't. Ev is model of Darwinian evolution except for the fact that,
unlike the Darwinian model, the fitness landscape was intelligently
designed. The "watchmaker" is not "blind". It was endowed with "sight"
from intelligent designers. Is this how nature works?

Let's take another example. You are aware that there are ferromagnets
in nature, right? Like iron, nickel, and cobalt. In these materials,
magnetic moments tend to line up in the same direction at low
temperatures. Naturally. Nature is blind of course.
On the other hand, we have physical models of magnets such as the Ising model.
We know that the lowest-energy configurations of spins in this model
are ones with all spins pointing up and all spins pointing down. We can
also simulate the ordering process via on of the Monte Carlo methods,
which includes random changes to the state and feedback from the
environment that encourages the magnet to go downward in the energy
landscape.
Here is a question for you, kornbelt. Does the Ising model emulate a
natural process or a designed one? There are great parallels with ev
here, in more ways than you can appreciate.
Could have been but some patterns lead one to suspect
natural causes i.e. storms. Physical features determine plausible
conclusions.
But the plausibility of a natural process does not rule out an
artificial origin, does it? A human designer could have faked the
effects of a storm, right?
If you answer yes to this, you have to agree that there is no way to
detect design. One can only try to rule out a natural cause. Right?
Do you have such a filter that doesn't presume true randomness exists?
Discontinuity suggest a basis for a filter. We observe organisms
requiring a minimal degree of genomic complexity to sustain life. We
know of no process consistent with current theories able to bridge a
chasm between inert matter and a self-replicating cell. The
discontinuity is a double gilded gap. For naturalists it suggest we
simply have not found nature's hidden process. For a Dembski IDist it
suggest the exact circumstance one would look for to identify a causal
nexus where intelligence bridges a gap.
Olegt: If you answer yes to this, you have to agree that
there is no way to detect design. One can only try to rule out a
natural cause. Right?
Dembski addressed the false negative/false positive dilemma years
ago. There will be false negatives in the sand- sand shifted
deliberately by human feet but indistinguishable from natural forces
able to accomplish the same. But natural forces do not generate sand
castles.
Do you agree that it makes no sense to ask the question "Is this an
ID model?" Any process, including a naturally occurring one, could have
been designed. Chemists make the same compounds nature does.
olegt: Do you agree that it makes no sense to ask the
question "Is this an ID model?" Any process, including a naturally
occurring one, could have been designed. Chemists make the same
compounds nature does.
This is the fatal flaw with the ID argument: it needs to separate "design" from "natural" in nature.
It's ALL designed. This is why chemists can reproduce the compounds God made: because he designed them to bond a certain way.
Now, olegt has no explanation as to why nature is made up of objects
that seem to always behave as if they are programmed to do what they do.
He has no explanation as to why nature is predictable. He has no
explanation as to why nature seems to behave lawfully.
He dismisses form and essence as medieval (and therefore useless)
ideas. Yet form, essence, causality – all of these things are at the
heart of nature.
olegt does not want to discuss that. He'd rather make ID proponents
look silly (or so he thinks) by pointing out the obvious – everything in
nature could have been designed. Yet, by doing so he unwittingly
acknowledges that nature behaves as if designed.
And that's why he clams up when we try to discuss nature at a fundamental level.
Discontinuities happen all the time. It is why this flame is green.
We live in a digital (i.e. quantum) universe where stars can explode suddenly.
As I have indicated before, I suggest scientists tend to focus on
matching data to models (usually with built-in Discontinuities). Ev is
one such model. If it continues to match observations then it is a
useful model, right?
If you and Ken Miller see a rabbit (i.e. a design) then so be it. It
doesn't seem to make a difference as to how science is done.
Do you agree that it makes no sense to ask the question "Is this an ID
model?" Any process, including a naturally occurring one, could have
been designed. Chemists make the same compounds nature does.
That makes no sense to me, how is something that is naturally occurring , designed?
Olegt, you apparently don't understand the distinction between two
indistinguishable events, but nevertheless had two different causes.
Just because some events can't be distinguished doesn't mean " Any
process, including a naturally occurring one, could have been designed."
that statement makes no sense.
Oleg and I have argued in the past about whether or not models are "just math".
If something is indistinguishable to scientific modeling it can be argued it is immaterial to scientific study.
If all of nature can be considered to be designed, it makes no sense
to math-focused scientists to argue about whether some things exhibit
design better than others. It doesn’t affect the math.
No that doesn't help at all. How can something be both designed and
have occured naturally? Just because there may be times when you can't
distinguish causes, doesn't mean "any process, including a naturally
occurring one, could have been designed" That's just plain nonsensical.
Either something is rationally designed, or it occurred naturally.
But back to the sentence in question: if two events are
indistinguishable, and one of them is known to have artificial origin,
obviously the other one could have had the same origin. Don't you think?
Oh I see what you're saying. Human designers can mimic things that
naturally occur and natural processes can mimic human design. So what?
Are you saying that because one can mimic the other that we can never
hope to come to some kind of reasonable explanation as to the cause of any event?
Let's take the case of carbon atoms, Guts. We know how they can arise naturally in stars. This knowledge, however, does not
exclude the possibility that any given carbon atom has been synthesized
in a lab by physicists. You just can't tell the difference.
What is the model for the origin of a biological genome?
I was going to ask you to go first but I strongly suspected you would
rather continue to avoid it. But, who knows, you might surprise me and
actually provide a readily understandable summary of your position.
Therefore, I will go first…
One of my main focus points is understanding how Vernanimalcula guizhouena
came into existance. This Precambrian animal was bilateral with a
differentiated gut, a mouth, an anus, and paired external sense organs
(eyes?). Compared to this, the evolution of modern lifeforms was
trivial.
I understand life had three billion years to go from prokaryotes to
the Vernanimalcula guizhouena. It is evident life started taking
advantage of quantum effects very early. We now know the role quantum
entanglement plays in photosynthesis. (link) We also have discovered the DNA search algorithms strongly suggest quantum processing.(link)
Therefore, I presume life has had enough time and extreme processing
power to convert information gained via quantum effects into lifeforms
as complex as the Vernanimalcula guizhouena.
The next hurdle to address is the origin of DNA and prokaryotes. I
think the proponents of the RNA World have made their case. (link)
I could be talked out of it. But I think there was some kind of RNA half-step preceding DNA.
Bradford, as I indicated, I was going to let you go first but as it
happens Dr. GH at AtBC provided a link to his “short” summary of OOL.
1. The late Hadean Earth had a neutral to reduced
atmosphere and ocean system, a shallow, hot crust and a UV rich, "cold"
sun. Highly reduced oasis existed at hydrothermal vents and other
mineral rich locations,
2. Under those conditions, phospholipids, amino acids, nucleic bases,
and pentoses readily form (augmented by extraterrestrial sources such as
cometary delivery) and are concentrated by freezing and evaporation as
well as mineral surface plating, and encapsulation,
3. Amino acids spontaneously form short (8 to 20 aa’s) racemic peptides,
and random RNAs with as few as 2 types of nucleic bases have enzymatic
activity. Spontaneous phospholipid vesicles sequester these peptides as
transmembrane pores, and along with enzymatic RNAs plated to mineral
grains such as montmorillonite, calcite, and metal sulfides.
4. Electron potential differences are exploited from transmembrane pores
to form adenine triphosphate, establishing the first metabolism,
5. These ancient first cells were racemic, using both L- and D- amino acids because they were readily available,
6. Biological and geochemical events reduced the availability of D- aa's,
7. These ancient cells evolved racemases to maintain/sustain their
existing metabolic pathways as attested by L- to D- amino acid racemases
found even in humans. Ergo: The chirality "problem" in OOL isn't a
problem.

Well, we have all the pieces. Our planet was formed from massive
collisions of planetoids that had undergone independent evolution and
weathering which retained much of their atmospheres to add to the
growing planet Earth. We have amino acids, sugars, nucleic acid bases,
lipids and minerals under an anoxic to reducing atmosphere and ocean
with a thin hot crust and a UV rich cold Sun. Plus, remember that the
Moon is closer and orbiting faster producing massive tidal flows
compared to modern times.
Will these combine to make any thing?
Yep, they sure will:

(This is more of historic interest, but recall that ATP is the energy
carrier for all cells.)
Someone in an email asked why I posted so many references.
There are several reasons. First, that is how science is done, we build on the work of others.
Second, when we use referenced data to make a point clear we state
the source of our information up front. Anyone can read these papers. If
they want, they can argue that I have misread the article, or that the
article itself has been refuted by more up-to-date information.
Third, a common creationist claim is that there is no valid research
on the origin of life, or that the research done is inconclusive. The
references I have cited are evidence that these claims are false.
Fourth, except for some historical references, my sources are mostly
less than 10 years old, and some are even less than 10 months old. This
is in direct contrast to the selective use by creationist writers such
as Jonathon Sarfati, or Jon Wells, who use a few out of date and refuted
articles to puff up their nonsense.
So, there you have it.
Here is the link to Dr. GH's post. It includes a lot more references and discussions on chirality.
However, Dr. GH focused mostly on the hardware.
My presumption for life's software and source of information is via
Quantum Mechanics. If there is a designer, it looks like he/she/it/they
manipulate life through quantum effects.
The origin of life necessitated the formation of
catalytic functionalities in order to realize a number of those capable
of supporting reactions that led to the proliferation of biologically
accessible molecules and the formation of a protometabolic network.
Here, the discussion of the significance of quantum behavior on
biological systems is extended from recent hypotheses exploring brain
function and DNA mutation to include origins of life considerations in
light of the concept of quantum decoherence and the transition from the
quantum to the classical. Current understandings of quantum systems
indicate that in the context of catalysis, substrate-catalyst
interaction may be considered as a quantum measurement problem.
Exploration of catalytic functionality necessary for life’s emergence
may have been accommodated by quantum searches within metal sulfide
compartments, where catalyst and substrate wave function interaction may
allow for quantum based searches of catalytic phase space. Considering
the degree of entanglement experienced by catalytic and non catalytic
outcomes of superimposed states, quantum contributions are postulated to
have played an important role in the operation of efficient catalysts
that would provide for the kinetic basis for the emergence of life.
Ok Bradford… Your turn… What's your model?
P.S. I thank Bilbo in advance for allowing this off-topic discussion.
I have managed to get myself locked out of the Open Thread.
The EV program is admittedly a targeted search and as such does not
model Darwinian evolution. Therefore Tom Schneider has lied or even
worse, he, a evolutionary biologist, is ignorant of the theory of
evolution.

1996 “A self-replicating peptide.” Nature Aug 8;382(6591):525-8
Pulllease- here we have a polypeptide of 32 amino acids. Then they
add two polypeptides – one of 15 AA and the other of 17 AA- The 15 and
17 are the same as the first 15 and last 17 of the 32 AA string.
The 32 AA string facilitates the bond between one 15 AA and one 17
AA- ONE peptide bond- everything else was provided by the scientists.
Oh those 15 and 17 aa peptide strings- yup they match the 32AA- that
is the 17 AA string matches the first 17 AA of the 32 AA string and the
15 AA string matches the last 15 AA of the 32 AA string.
olegt: Here is a question for you, kornbelt. Does the Ising model emulate a natural process or a designed one?
A natural process that may be designed.
At any rate, the difference between Ev and the Ising modeling is that
Ising is known to be analogous to the process it is simulating. Ev is
not known to be analogous to nature with respect to "blind fitness." In
other words, Ev is positively not an example of a blind fitness
context. Therefore it is not "proof of concept." For some reason the
significance of that alludes you.
All Ev does is reward changes that conform to a set of fitness
criteria. And it shows no capability for building up the kind of
"mechanical" complexity we see in nature. Whoop-dee-doo. It is not known
to be analogous to what is actually happening in nature. You Isling model citation is not analogous to Ev.
Comment by kornbelt888 — December 20, 2010 @ 12:00 pm
Dr. GH at AtBC provided a link to his “short” summary of OOL.
Sorry that's not a summary of OOL. It's mostly a summary of research,
and a rather uncritical summary at that. He seems to be trying to
countering some "creationist claim" that there is no valid research on
OOL. (A claim that you probably won't find around here since we try to
keep up with OOL research as it happens)
I realize that you are simply letting Gary Hurd do your thinking for
you, but in the process of copying and pasting his thoughts did you
happen to come across the explanation for spontaneous purine synthesis?
Also, using your/Gary's model, can you explain in any detail the leap
from protocell replication (elongation and agitation under static
charge) to modern cellular reproduction (prokaryotic fission,
chromosomal segregation and cytokenesis)? Also, please explain the
mechanism by which cells went from inhabiting existing lipid vesicles to
manufacturing their own lipid vesicles.
Once you get past the literature bluff and start to think critically
about these and other questions you'll begin to see OOL research for
what it currently is:
A) A bottom up approach which has discovered several pieces of a
naturalistic Rube Goldberg for production of intelligent life. Still
very incomplete, the conceptual Rube Goldberg is growing and becoming
more and more complex as it does so.
[The Szostak lab recently produced a more succinct and relevant summary here.]
B) A top-down approach which has discovered several pieces of a
synthetic program for intelligently designing life. Still very
incomplete, this program is growing and becoming more streamlined and
efficient as things progress.
[Look to J. Craig Venter's lab and Church and Jewett at Harvard for the cutting edge developments.]
At any rate, if thinking for yourself is really your goal (as you've
repeatedly stated), then I'd advise against copying and pasting broad
swaths from known culture warriors that you've met at the swamp like
Hurd. These agenda driven crackwhores prefer to use science as a
bludgeon to attack religion rather than use it as a tool for
understanding.
It's up to you, TP. You can do some critical thinking, or you can simply follow the Hurd!
Geez, you guys don't even slow down for Christmas do ya? Get out
there and sing some Christmas carols. And TP, olegt, get your asses to
church! And TP, for chrissake, no talking about quantum physics there.
Just shaddup and sing for a change.
Anyway, some quick comments before I return to the fun of making
cookies, enjoying the holiday and last minute shopping. One by one.
Guts,
How can something be both designed and have occured naturally?
DS already answered this aptly, but I'll second the response and
repeat it: If nature is designed, then what "occurs naturally" can be
designed as well. That's one of the principal non-atheist complaints of
ID, and one I think has merit – they put 'design' in the running with
'nature', as if the two must be opposed. That's just not necessarily the
case.
Comment by nullasalus — December 20, 2010 @ 9:26 pm
While I have a special response for olegt, I want to note the
flipside of olegt's claim. He claims that "an omniscient, omnipotent
designer" could be responsible for each and every pattern we see. But
the flipside of this is that, in principle, "nature" can be responsible
for each and every pattern we see too – including the ones we normally
attribute to minds.
"Natural processes", whatever those are, could have resulted in this
lovely HDTV I've got in front of me. Maybe it was all chance. Maybe it's
a kind of natural process we don't understand yet (sound familiar to
anyone?) As I wrote in my naturalist YEC post a while back, 'nature' or
'nature + luck' is dramatically unbounded in principle.
Comment by nullasalus — December 20, 2010 @ 9:32 pm
Do you agree that it makes no sense to ask the question
"Is this an ID model?" Any process, including a naturally occurring one,
could have been designed. Chemists make the same compounds nature does.
Dear God. You really are a TE, aren't you? All this time you've been saying you're an atheist – you're just eastern orthodox.
Olegt here is unleashing the atomic bomb of anti-ID arguments. In
fact – Mike, please take no offense at this – he sounds like Mike Gene
here. To take olegt at his word here means that not only is there no,
but there cannot be 'science versus religion/God' conflict. Not in
evolution, not in the OoL, not in anything – because each and every
'scientific explanation' can and would double as a design explanation,
with no way to settle the dispute decisively.
I am calling this the atomic bomb of anti-ID arguments because it
wipes everyone off the map. It wipes out Dawkins along with Dembski, it
takes out Behe along with Ruse. There reason it "makes no sense" to ask
if ev or this or that "is an ID model" is because the answer is obvious:
"Sure, why not." Any given model of what happened or happens in nature
can be a reflection, however imperfectly, of a designer's intent. In
which case no one's ever provided a model of "unguided, blind nature"
that wasn't just a needless, extraneous assertion of same on their part.
Incidentally, note that "omnipotence and omniscience" is not strictly
needed here. One doesn't need to be omniscient to have evolution guided
towards even extremely specific ends – they just need to be quite smart
and capable. You'll note that Francis Crick didn't start talking about
omniscient, omnipotent aliens when it came to the OoL question – regular
ones would do the trick.
But there's another, nastier problem for olegt. See, each and every
one of us – simply by virtue of responding to this thread – have
first-person, undeniable, subjective experience that design is a real
phenomenon. We arrange letters according to intent. But this "unguided,
blind" crap? According to olegt's view, none of us have seen it – and
none of us ever can. All we can see is some empirical 'stuff' that could
just as easily be attributed to design as non-design. And that puts us
in a curious position: "Design", we know exists to some degree,
undeniably – and it can explain all we see. "Non-design", in principle,
may not exist whatsoever, and it explains nothing that Design doesn't
explain already.
But either way, to see olegt deploy the atomic bomb – and thus cut
off over a hundred years of atheist apologetics at the knees – warms my
black heart. In fact, I consider it a Christmas gift! Thanks, olegt!

How do you understand the term “signs” in the New Testament? It seems
to me that these are phenomena that have a clear hallmark of design and
that can serve as a kind of calling card of Yahweh.
In the Bible everything is not a “sign” only some things are.
In your schema how do you understand such things.

I'd need you to be more specific. Are you talking miracles, or express attempts at communication by Yahweh?
If so, consider this. Imagine a piece of paper God creates. And when I
say creates, I mean a full-blown ex nihilo creation of every particle
and atom, on the spot. And on this paper are the words "Nullasalus, get
your ass to church."
In that case, I think it's clear that everything in that paper is
'designed'. But the paper itself isn't telling me 'go to church'. It's
the pattern formed by the ink, the intention behind it, and my ability
to read the intention.
Does that address your question at all?
Comment by nullasalus — December 20, 2010 @ 10:05 pm

The Bible talks of signs and wonders(miracles). A sign might be a
miracle as in multiplying loaves and fish (John 6:14) Or it might be
just an unlikely occurrence like a baby in a manger (Luke 2:12).
What makes a sign a sign is that it does not look natural it reeks of design.
It's the pattern formed by the ink, the intention behind it, and my ability to read the intention.
Sorry but I’m not sure I follow. If I gave you a piece of paper
saying get your ass to church it might be a message from God but it
would not be a sign regardless of intent.
Signs are special………..
They show that Aslan is a foot.
This man came to Jesus by night and said to him, "Rabbi, we know that
you are a teacher come from God, for no one can do these signs that you
do unless God is with him." (John 3:2)
Yet many of the people believed in him. They said, "When the Christ
appears, will he do more signs than this man has done?" (John 7:31)

What makes a sign a sign is that it does not look natural it reeks of design.
I'd say what makes a sign a sign is that it's of a particular type of
design, even among the backdrop of a greater design. And remember, the
example I gave wasn't just 'here's a paper' – I specified for the sake
of argument exact how that paper and ink and even that atoms within it
came to be. It's miraculous through and through, you can even say the
entire thing is a 'sign' given that context – but still, the 'entire
paper' wasn't communicating, nor did it need to.
If you want another example, consider a multiplayer online game. The
entire game can be designed top to bottom, but an act by an admin or GM
could be designed as well, yet in a way which stands out against that
greater design. 'Only an admin/GM could do that'.

What makes a sign a sign is that it teaches a spiritual message.
Both the feeding with the loaves and the babe in the manger harken to
Jesus’s teachings. The miracles of the NT are not gratuitous displays
of power, as we might expect from a trickster God, but as displays of
God’s character and teachings.

You are welcome, nullasalus. This gift is a Trojan horse, so enjoy the ride!
I would like to see a reference followed by a more or less complete
explanation as to what relevance it has to OOL research. I've never seen
that done. One of my complaints about ool is that yes, many of the
players can be gotten, but how does it all fit together? The
meta-question is “How did the dissipative systems begin to become more
complex?”
ID Guy: The "pattern" of leaves on the ground (think
autumn up North) is not designed but left to chance. The shape of
clouds- left to chance.
But what do you mean by "chance?"
Any statistically stochastic set of events in nature could be the
result of a very sophisticated deterministic algorithmically based
random number generator. If that were the case, a very smart
intelligence might know the state of the generator(s) at every step,
even though we might not have a prayer in figuring out the algorithm.
So, what Daniel says is not conceptually untenable. If stochasm is not
based on a deterministic algorithm, then we are left with grappling with
some concept of "true randomness", i.e, events without a clear cause,
which is inconceivable. It still may be true, but it is inconceivable.

ID guy: Is that in the Bible or just your say-so or do you have some reasonable argument?
It is based on the definition of "omniscient".
Nothing can be "unaccounted for" to an omniscient being. (See my machine analogy for clarification.)
If God knows everything, then he knows beforehand the pattern the leaves will form on the ground and—since he designed every factor that controls the leaves—even their pattern can be said to be by design.
The definition of omniscient is from fallable humans. And I don't see God as a micromanager.

Apparently the setup is this: Researchers come up with EV, claiming it simulates evolution in nature. They also claim EV is a 'blind, unguided' search.
This paper argues that actually EV is a targeted search.

You have no idea what ev does, do you? Maybe you should read a brief description of the program on Tom Schneider's site. Perhaps you will find something like this:
From this passage, one may reasonably conclude that the evolutionary process modeled by ev has two parts: (1) random, unguided mutations and (2) non-random, guided selection. It is a targeted search in the sense that there is a fixed genetic sequence with the best chance of survival and digital organisms invariably converge to that sequence when the program is run.
Note that Schneider wrote this in 2001. If it took 9 years to realize that ev is a targeted search, boy, are they slow!

Further correction-
EV was detected as a bogus example for "evolution" when it was first presented as such an example.
That it was just recently put in a peer-reviewed paper- what has been known for some time- is not any indication of when it was known.
Also from the way EV actually is written it is reasonable to conclude that all reproduced sequences are matched against a TARGET and then selected. IOW there is a fixed sequence- a target- that the mutated sequences are trying to match. The better the match the better the chance of survival and reproduction.

So, let's assume Dembski and company are right in their paper. Does this mean that ev, insofar as it is offered as a model of nature, is in fact an ID model?
Dembski, Marks and company claim: ev is an evolutionary search algorithm proposed to simulate biological evolution. As such, researchers have claimed that it demonstrates that a blind, unguided search is able to generate new information.
So, what are you saying here olegt? That no researchers claim claim that evolution is "blind" or "unguided" in any sense relevant to this paper? That they do, but they're full of crap and speaking nonsense? Or maybe you're saying that evolution is guided and the arrival of various species, humans included, was downright inevitable?

I explained my understanding of ev here. It has a random component (mutations) and a non-random one (selection of a pre-specified target). Tell us what you mean by "a 'blind, unguided' search." I have asked you, like, a bazillion times and you have been unable to explain.

Well, we've gone back and forth enough times. Let's review.
The second paragraph is patently wrong. It is well known that ev has a fixed target that is known in advance. Schneider's 2001 description of the program explicitly mentions that.
There is no need for "ID researchers" to prove that ev is a targeted search.
The first paragraph contains an ill-defined term 'blind, unguided' search. The meaning of this term remains obscure despite multiple inquiries directed at its creator.

Tom Schneider sed EV modeled classic Darwinian principles. So either he is a liar or he is ignorant of classic Darwinian principles.
Now olegt sez "ev is a model of evolution"- well it ain't a model of biological evolution as biological evolution does not posit targeted searches. OTOH ID does posit targeted searches as a mechanism.

kornbelt,
What you just did is tautological: ev is an ID model because ev is an ID model.
What you should do is point me to a description of an ID model that is described elsewhere, compare to to ev and then declare victory.
I am not holding my breath, though. One of the ID luminaries, who coauthored the paper we are discussing, wrote this once:
So, no, by very definition, ID does not do models. A designer can do whatever he wants. Particularly if he is omnipotent. No point in trying to model that.

Hi Kornbelt,
You asked…
This is the kind of hypothetical question politicians avoid for good reason because their answers will often be taken out of context and become headline news.
Since I’m not running for office I’m not shy about agreeing that ev can be thought of as a model in support of ID Science.
The usual problem comes down to the definition of "intellegence".
If "intelligence" is the "ability to learn and adapt" then Natural Selection provides life a kind of intelligence in a macro sense.
I happen to think there is additional "intelligent" coordination in life via quantum links.
However, evidence of intelligence does not automatically mean a purposeful designer is involved.
Comment by Thought Provoker — December 19, 2010 @ 10:36 am
December 19th, 2010 at 10:41 am
The omnipotency of the designer means that any model is an ID model. So arguing whether this or that is an ID mechanism is pointless. Any natural process could be faked by a skillful designer.
At the same time, ev is clearly a Darwinian model. It has all the requisite ingredients: random variations, heritability, and selection. It is a very simple model: e.g., it has a fixed fitness landscape with a single minimum. So it cannot be used to understand coevolution. But that's what models are for: they are simplified versions of reality.

This is a bogus argument. Observe the beach goer. Moves small mounds of sand when walking. Wind accomplishes the same. Was that sand purposely shifted by those feet? Perhaps. But design would be undetectable to an investigator. OTOH, a sandcastle is a different kettle of fish. Design can be present but whether it is detectable is a separate issue. That not all causal trails lead to design detection, even where the omnipotent cause was present, makes a practical distinction between omnipotence and evidence for design.

Not all sand patterns are attributed to design. A sandcastle is. A wavy mound may or may not be designed. There is a design sifter at work here.
As for the possibility that natural forces are insufficient to generate an outcome, that should not be dismissed as an option by rational minds. Discontinuity. Therein lies an indicator of insufficiency.

Olegt, you need to make a distinction between a theological tenet- omnipotence- and design detection. The former posits a broad claim of all the physical universe resulting from a singular causal source. The latter makes a distinction among parts of the created universe. Some provide evidence of a causal trail leading to an intelligent source by virtue of their physical properties. Others can lead to that same source only by imputing conceptual explanations that are extrinsic to the physical reality of that which is observed.

For the sake of argument (only) – That would be why we need POSITIVE evidence for a designer's presence. (However I am not sure that any sand pattern could have been created by a (human) designer- what about patterns dated to before humans were supposed to be around?) IOW we don't infer a designerdidit until BOTH conditions are met.

No need to wax philosophical. The question was much simpler and more specific: do you agree that pretty much any sand pattern (within physical limits) could have been created by a human designer?

It certainly makes sense to ask that question. I think you mean to say that the answer is irrelevant with regards to Ev's significance. But it isn't. Ev is model of Darwinian evolution except for the fact that, unlike the Darwinian model, the fitness landscape was intelligently designed. The "watchmaker" is not "blind". It was endowed with "sight" from intelligent designers. Is this how nature works?

On the other hand, we have physical models of magnets such as the Ising model. We know that the lowest-energy configurations of spins in this model are ones with all spins pointing up and all spins pointing down. We can also simulate the ordering process via on of the Monte Carlo methods, which includes random changes to the state and feedback from the environment that encourages the magnet to go downward in the energy landscape.
Here is a question for you, kornbelt. Does the Ising model emulate a natural process or a designed one? There are great parallels with ev here, in more ways than you can appreciate.

Discontinuity suggest a basis for a filter. We observe organisms requiring a minimal degree of genomic complexity to sustain life. We know of no process consistent with current theories able to bridge a chasm between inert matter and a self-replicating cell. The discontinuity is a double gilded gap. For naturalists it suggest we simply have not found nature's hidden process. For a Dembski IDist it suggest the exact circumstance one would look for to identify a causal nexus where intelligence bridges a gap.

This is the fatal flaw with the ID argument: it needs to separate "design" from "natural" in nature.
It's ALL designed. This is why chemists can reproduce the compounds God made: because he designed them to bond a certain way.
Now, olegt has no explanation as to why nature is made up of objects that seem to always behave as if they are programmed to do what they do. He has no explanation as to why nature is predictable. He has no explanation as to why nature seems to behave lawfully.
He dismisses form and essence as medieval (and therefore useless) ideas. Yet form, essence, causality – all of these things are at the heart of nature.
olegt does not want to discuss that. He'd rather make ID proponents look silly (or so he thinks) by pointing out the obvious – everything in nature could have been designed. Yet, by doing so he unwittingly acknowledges that nature behaves as if designed.
And that's why he clams up when we try to discuss nature at a fundamental level.

Hi Bradford,
You asked…
I was going to ask you to go first but I strongly suspected you would rather continue to avoid it. But, who knows, you might surprise me and actually provide a readily understandable summary of your position. Therefore, I will go first…
One of my main focus points is understanding how Vernanimalcula guizhouena came into existance. This Precambrian animal was bilateral with a differentiated gut, a mouth, an anus, and paired external sense organs (eyes?). Compared to this, the evolution of modern lifeforms was trivial.
I understand life had three billion years to go from prokaryotes to the Vernanimalcula guizhouena. It is evident life started taking advantage of quantum effects very early. We now know the role quantum entanglement plays in photosynthesis. (link) We also have discovered the DNA search algorithms strongly suggest quantum processing.(link) Therefore, I presume life has had enough time and extreme processing power to convert information gained via quantum effects into lifeforms as complex as the Vernanimalcula guizhouena.
The next hurdle to address is the origin of DNA and prokaryotes. I think the proponents of the RNA World have made their case. (link)
I could be talked out of it. But I think there was some kind of RNA half-step preceding DNA.
Bradford, as I indicated, I was going to let you go first but as it happens Dr. GH at AtBC provided a link to his “short” summary of OOL.
Here is the link to Dr. GH's post. It includes a lot more references and discussions on chirality.
However, Dr. GH focused mostly on the hardware.
My presumption for life's software and source of information is via Quantum Mechanics. If there is a designer, it looks like he/she/it/they manipulate life through quantum effects.
I am partial to A. Patel. His papers include…

However, Patel isn't the only one considering the origin of the genetic code is related to Quantum Mechanics. Here is the abstract of the 2010 paper titled…
Speculation on Quantum Mechanics and the Operation of Life Giving Catalysts
Ok Bradford… Your turn… What's your model?

So all deaths, including naturally occurring deaths, could be homicides. And all rocks, including naturally occurring rocks, could be artifacts.
It all boils down to parsimony, as in what is the minimum it takes to do X.
Science deals with the HOW things came to be the way they are. Methinks olegt doesn't understand that.

Back to the topic-
The EV program is admittedly a targeted search and as such does not model Darwinian evolution. Therefore Tom Schneider has lied or even worse, he, a evolutionary biologist, is ignorant of the theory of evolution.
Is this really what evolutionary "science" has become?

Pulllease- here we have a polypeptide of 32 amino acids. Then they add two polypeptides – one of 15 AA and the other of 17 AA- The 15 and 17 are the same as the first 15 and last 17 of the 32 AA string.
The 32 AA string facilitates the bond between one 15 AA and one 17 AA- ONE peptide bond- everything else was provided by the scientists.

Oh those 15 and 17 aa peptide strings- yup they match the 32AA- that is the 17 AA string matches the first 17 AA of the 32 AA string and the 15 AA string matches the last 15 AA of the 32 AA string.

olegt: Here is a question for you, kornbelt. Does the Ising model emulate a natural process or a designed one?
A natural process that may be designed.
At any rate, the difference between Ev and the Ising modeling is that Ising is known to be analogous to the process it is simulating. Ev is not known to be analogous to nature with respect to "blind fitness." In other words, Ev is positively not an example of a blind fitness context. Therefore it is not "proof of concept." For some reason the significance of that alludes you.
All Ev does is reward changes that conform to a set of fitness criteria. And it shows no capability for building up the kind of "mechanical" complexity we see in nature. Whoop-dee-doo. It is not known to be analogous to what is actually happening in nature. You Isling model citation is not analogous to Ev.

TP:
Sorry that's not a summary of OOL. It's mostly a summary of research, and a rather uncritical summary at that. He seems to be trying to countering some "creationist claim" that there is no valid research on OOL. (A claim that you probably won't find around here since we try to keep up with OOL research as it happens)
I realize that you are simply letting Gary Hurd do your thinking for you, but in the process of copying and pasting his thoughts did you happen to come across the explanation for spontaneous purine synthesis? Also, using your/Gary's model, can you explain in any detail the leap from protocell replication (elongation and agitation under static charge) to modern cellular reproduction (prokaryotic fission, chromosomal segregation and cytokenesis)? Also, please explain the mechanism by which cells went from inhabiting existing lipid vesicles to manufacturing their own lipid vesicles.
Once you get past the literature bluff and start to think critically about these and other questions you'll begin to see OOL research for what it currently is:
A) A bottom up approach which has discovered several pieces of a naturalistic Rube Goldberg for production of intelligent life. Still very incomplete, the conceptual Rube Goldberg is growing and becoming more and more complex as it does so.
[The Szostak lab recently produced a more succinct and relevant summary here.]
B) A top-down approach which has discovered several pieces of a synthetic program for intelligently designing life. Still very incomplete, this program is growing and becoming more streamlined and efficient as things progress.
[Look to J. Craig Venter's lab and Church and Jewett at Harvard for the cutting edge developments.]
At any rate, if thinking for yourself is really your goal (as you've repeatedly stated), then I'd advise against copying and pasting broad swaths from known culture warriors that you've met at the swamp like Hurd. These agenda driven crackwhores prefer to use science as a bludgeon to attack religion rather than use it as a tool for understanding.
It's up to you, TP. You can do some critical thinking, or you can simply follow the Hurd!

Hi chunkdz,
One of the problems with commenting on blogs is while responding to one person others can come in and attack from a different direction.
Bradford made a request.
I have attempted to respond to that request.
While it is likely he, too, will be dissatisfied with my response it would be reasonable of me to ask Bradford to answer his own request.
Which is why I ended my comment with…
Since you have decided to join in the fun, hopefully you are prepared to respond to Bradford's request.
After you do that, I would be more than happy to do a compare and contrast.
Meanwhile, I thank you for pointing out some specific areas for me to look into. This is one of the main reasons I comment on blogs.
I like to provoke thinking, especially my own.

Guts,
DS already answered this aptly, but I'll second the response and repeat it: If nature is designed, then what "occurs naturally" can be designed as well. That's one of the principal non-atheist complaints of ID, and one I think has merit – they put 'design' in the running with 'nature', as if the two must be opposed. That's just not necessarily the case.

Bradford,
While I have a special response for olegt, I want to note the flipside of olegt's claim. He claims that "an omniscient, omnipotent designer" could be responsible for each and every pattern we see. But the flipside of this is that, in principle, "nature" can be responsible for each and every pattern we see too – including the ones we normally attribute to minds.
"Natural processes", whatever those are, could have resulted in this lovely HDTV I've got in front of me. Maybe it was all chance. Maybe it's a kind of natural process we don't understand yet (sound familiar to anyone?) As I wrote in my naturalist YEC post a while back, 'nature' or 'nature + luck' is dramatically unbounded in principle.

olegt,
Dear God. You really are a TE, aren't you? All this time you've been saying you're an atheist – you're just eastern orthodox.
Olegt here is unleashing the atomic bomb of anti-ID arguments. In fact – Mike, please take no offense at this – he sounds like Mike Gene here. To take olegt at his word here means that not only is there no, but there cannot be 'science versus religion/God' conflict. Not in evolution, not in the OoL, not in anything – because each and every 'scientific explanation' can and would double as a design explanation, with no way to settle the dispute decisively.
I am calling this the atomic bomb of anti-ID arguments because it wipes everyone off the map. It wipes out Dawkins along with Dembski, it takes out Behe along with Ruse. There reason it "makes no sense" to ask if ev or this or that "is an ID model" is because the answer is obvious: "Sure, why not." Any given model of what happened or happens in nature can be a reflection, however imperfectly, of a designer's intent. In which case no one's ever provided a model of "unguided, blind nature" that wasn't just a needless, extraneous assertion of same on their part.
Incidentally, note that "omnipotence and omniscience" is not strictly needed here. One doesn't need to be omniscient to have evolution guided towards even extremely specific ends – they just need to be quite smart and capable. You'll note that Francis Crick didn't start talking about omniscient, omnipotent aliens when it came to the OoL question – regular ones would do the trick.
But there's another, nastier problem for olegt. See, each and every one of us – simply by virtue of responding to this thread – have first-person, undeniable, subjective experience that design is a real phenomenon. We arrange letters according to intent. But this "unguided, blind" crap? According to olegt's view, none of us have seen it – and none of us ever can. All we can see is some empirical 'stuff' that could just as easily be attributed to design as non-design. And that puts us in a curious position: "Design", we know exists to some degree, undeniably – and it can explain all we see. "Non-design", in principle, may not exist whatsoever, and it explains nothing that Design doesn't explain already.
But either way, to see olegt deploy the atomic bomb – and thus cut off over a hundred years of atheist apologetics at the knees – warms my black heart. In fact, I consider it a Christmas gift! Thanks, olegt!

Hey Null and DT,
I have a theological question for you all.
How do you understand the term “signs” in the New Testament? It seems to me that these are phenomena that have a clear hallmark of design and that can serve as a kind of calling card of Yahweh.
In the Bible everything is not a “sign” only some things are.
In your schema how do you understand such things.

fmm,
I'd need you to be more specific. Are you talking miracles, or express attempts at communication by Yahweh?
If so, consider this. Imagine a piece of paper God creates. And when I say creates, I mean a full-blown ex nihilo creation of every particle and atom, on the spot. And on this paper are the words "Nullasalus, get your ass to church."
In that case, I think it's clear that everything in that paper is 'designed'. But the paper itself isn't telling me 'go to church'. It's the pattern formed by the ink, the intention behind it, and my ability to read the intention.
Does that address your question at all?
Comment by nullasalus — December 20, 2010 @ 10:05 pm
December 20th, 2010 at 10:32 pm
The Bible talks of signs and wonders(miracles). A sign might be a miracle as in multiplying loaves and fish (John 6:14) Or it might be just an unlikely occurrence like a baby in a manger (Luke 2:12).
What makes a sign a sign is that it does not look natural it reeks of design.
Sorry but I’m not sure I follow. If I gave you a piece of paper saying get your ass to church it might be a message from God but it would not be a sign regardless of intent.
Signs are special………..
They show that Aslan is a foot.
This man came to Jesus by night and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him." (John 3:2)
Yet many of the people believed in him. They said, "When the Christ appears, will he do more signs than this man has done?" (John 7:31)

fmm,
I'd say what makes a sign a sign is that it's of a particular type of design, even among the backdrop of a greater design. And remember, the example I gave wasn't just 'here's a paper' – I specified for the sake of argument exact how that paper and ink and even that atoms within it came to be. It's miraculous through and through, you can even say the entire thing is a 'sign' given that context – but still, the 'entire paper' wasn't communicating, nor did it need to.
If you want another example, consider a multiplayer online game. The entire game can be designed top to bottom, but an act by an admin or GM could be designed as well, yet in a way which stands out against that greater design. 'Only an admin/GM could do that'.

Hi fmm,
What makes a sign a sign is that it teaches a spiritual message. Both the feeding with the loaves and the babe in the manger harken to Jesus’s teachings. The miracles of the NT are not gratuitous displays of power, as we might expect from a trickster God, but as displays of God’s character and teachings.

I would like to see a reference followed by a more or less complete explanation as to what relevance it has to OOL research. I've never seen that done. One of my complaints about ool is that yes, many of the players can be gotten, but how does it all fit together? The meta-question is “How did the dissipative systems begin to become more complex?”

I would say that chance still has a role- accidents still happen and randomness is still there.
The "pattern" of leaves on the ground (think autumn up North) is not designed but left to chance. The shape of clouds- left to chance.
Byproducts are not designed even though they wouldn't exist without the design.
I could go on and on…

If I design a machine and it behaves as expected, then everything it does is "by design".
If I design a machine and there are unexpected consequences, then those are not "by design" – although they could be said to be "caused by design".
If nature was designed by an omniscient God, then even chance and accidents are accounted for.
If it was designed by something less (a position that is metaphysically indefensible IMO), then chance and accidents are unaccounted for.

But what do you mean by "chance?"
Any statistically stochastic set of events in nature could be the result of a very sophisticated deterministic algorithmically based random number generator. If that were the case, a very smart intelligence might know the state of the generator(s) at every step, even though we might not have a prayer in figuring out the algorithm. So, what Daniel says is not conceptually untenable. If stochasm is not based on a deterministic algorithm, then we are left with grappling with some concept of "true randomness", i.e, events without a clear cause, which is inconceivable. It still may be true, but it is inconceivable.

It is based on the definition of "omniscient".
Nothing can be "unaccounted for" to an omniscient being. (See my machine analogy for clarification.)
If God knows everything, then he knows beforehand the pattern the leaves will form on the ground and—since he designed every factor that controls the leaves—even their pattern can be said to be by design.
