@jeeprs,
It doesn't contain. It represents. It expresses. It points to an immaterial agent that predetermines a specific manifestation into physical reality.

Information is immaterial. Nothing immaterial may be contained.

How do chemicals decide? We must be careful not to personify chemicals. This is the work of RNA. And the Nobel Prize Winner Barbara McClintock was demonized for two decades having to take her work underground until her findings could no longer be ignored that gene regulation was in fact controlled, and non random at all. James Schapiro and many others have confirmed her work. You'll notice a protein alphabet at the end of Yockey's model.

Yockey's model starts with the double helix. It has already been encoded. We don't know how. That's what we're trying to figure out in this discussion. Where did the genesis source of information come from? He simply takes us from double helix to final protein.

Yes, DNA is technically alphabet B. RNA is technically alphabet C. We don't know the source for the original alphabet A. Yockey's model does not address the original encoding of DNA. We've seen the physical mechanism, when genes are selected from both parents and assembled into one new double helix. We just don't know what drives or instructs that mechanism to do so.

My personal theory is that RNA is reading non coding pseudogenes, actively selecting the best it has to offer, and thereby instructing the two codes to combine. The Russians are making progress with this, as they are beginning to see that DNA/RNA is not binary, but has the efficiency of quaternary/ternary logic to process in a holographic manner.

I'm moving this weekend. But will attempt to provide the research as soon as I can. Thanks!

@richard mcnair,
I went to get Yockey's book out of the library previously, but it is technically challenging. But I do recall that there is a chapter addressing the issue of 'intelligent design' and denying that his book amounts to evidence for it. Although from the Amazon reviews, it seems that according to his theory, the 'origin of the code' (or life, as such) is not something we know or are likely to. (Of course this leaves a lot of space, which personally I am OK with. Space presents many possibilities.)

The second point that comes back to me was from lectures from the professor I had for Indian Philosophy, Dr Arvind Sharma. A phrase he used frequently in explaining Indian cosmology and the nature of Being, was that 'what was latent, becomes patent'. This is the idea that Brahman was always already 'latent' within the universe, (in the immanent aspect) and becomes manifest as living beings. Rather an Hegelian idea, but the phrase stayed with me.

I think what is coming out of all of this, for me, is the idea of the heirarchy of being. Of course Western material science is primarily concerned with one level of this heirarchy, namely the material level, which in the various traditional philosophies was understood as the lowest level. (Mind you, a lot has been done with it as a result of this concentration.) However it seems that various discoveries in all of the main sciences are unavoidably pointing towards other levels of the heirarchy of being. The nature of meaning is one such indication, but there are many others.

So this idea of 'the latent becoming patent' does that in that there is a kind of 'latent intelligence' in the universe which gradually becomes manifest in sentient beings. So again, this is the idea that intelligence doesn't evolve, our capacity for it evolves.

Whereas in the 'current scientific model', intelligence emerges only at the end of a very long evolutionary process having really been completely absent until it bootstraps itself into existence.

Yes, I've read elsewhere that Yockey is an atheist. In fact, as far as I know, all of my references are atheists or don't speak on the matter. Claude Shannon had a co-author to his book, Mathematical Theory of Communication, Weaver. I believe he is the only self proclaimed theist in the bunch. But I myself don't even know what the term theist means any longer. It's so, so... vague?

Intelligent Design is wrought with lies, ego, agenda... ignorance. It's embarrassing to be considered in that "camp", lumped together with hard 7 day creationists and the self proclaimed Name it and Claim it mega church pew parkers. Most of whom reject evolution altogether, but have no idea why.

I hope to promote the term, Intelligent Evolution. Noting that Darwin never mentioned the term Random Mutation in Origin of Species. He did however mention the need for an as yet unknown mechanism for Natural Selection to act upon. In the race to find that mechanism, Random Mutation was born. They may as well have called it Singularity. It means, "We don't know, but we can't let you know that. What would happen to our grants and funding?"

Barbara McClintock has handily demonstrated Controlled Mutation as the likely mechanism. I believe that quaternary(DNA)/ternary(RNA) logic is the next necessary acknowledgment to provide answers for the decision making capacity of the genome. Binary is just switches, yes or no, on or off, susceptible to cause and effect only. Quaternary/ternary can emulate "knowing".

jeeprs;106565 wrote:

Yes. More of this please. Very compatible with Bhartrihari and any teaching directed at principles of The Word, or The Way. Remember that Christianity was first called The Way. It wasn't called Christianity until religion got a hold of it.

Sound eerily familiar to Terrence McKenna and his rap about the Great Attractor. Rather than a Singularity that pushes outward from the beginning of time, this Great Attractor is actually pulling us inward, towards it, meeting at the end of time. His Novelty Theory concludes that time as 12/21/12 (independently of the Mayans or Hopi). Interesting fun side note, that 122112 maps to ABBAAB. Hebrew, as read left to right, is BAABBA. BA ABBA translates in English as "Father Returns".

Well there's a few slurs against scientists (good scientists anyway) in there.

I don't know what you mean when you say "random mutation was born" as if to say scientists now sum evolution up as random mutation. The random elements of reproduction are actually downplayed by most scientists - and exaggerated wildly by those who hope to equate randomness with chaos in order to reduce evolution to an absurdity.

Evolution is evolution. It doesn't need rebranding just because a single aspect of it is under some scrutiny as to exactly how big a role it plays (and even Barbara McClintock was working on the assumption that randomness plays a role).

As for scientists not admitting they don't know. I think that's pretty unfair. On a quest for knowledge you need be skeptical and admittedly ignorant in order to make the incremental steps required to edge closer to your goal. Scientists speaking honestly will admit they don't know - that they even don't know what they are sure of - and describe the implcations of what is known using tentative language. "It is thought that Tiktaalik provides a perfect example of a transitional form between fish and tetrapod", etc.

What scientists do like to do is hypothesise "it could be this, it could be that" - but that's just part of the process needed to forge ahead with the search - it isn't "please don't take our money away" anymore than any other justification for any other profession.

Quote:

She demonstrated a number of things, and factors favouring a degree of ability in some cellular processes to positively select for some mutations over other ones, or some unmutated stretch of genetic material over a mutated bit, are among them.

Her personal theological beliefs in regard to her study are not science.

Saying "she thinks transposition implies some sort of external intelligence, so if she's right about the science of transposition she must be right about the intelligence" is like saying "Richard Dawkins finds justification for atheism in his understanding of evolution, therefore evolution is atheist".

Wrong.

Her (or his) scientific understanding can inform her (or his) metaphysical philosophy all it wants - but that doesn't mean she (or he) has demonstrated the philosophy - just the science.

To state that that's "the likely mechanism" for natural selection is to jump ahead of oneself, because it's more apparent that natural selection resulted in the "error checking" processes.

I'm quite familiar, though I'm not sure pseudogenes are what you're thinking of. Pseudogenes are genes that do not get expressed, and this is often because they lack a promoter sequence. It would be very easy in the lab to pick up pseudogene expression, you can do reverse transcriptase-based PCR to amplify RNA transcripts, so any RNA gene product of a pseudogene would be picked up. There was one that I worked on -- no mRNA expression and no polypeptide at all. You may be thinking of gene silencing, which is partly done by siRNA (not mRNA). But I also don't want to hijack the discussion with too much scientific nuance, I mean we can talk about gene regulation and epigenetics all day but in the end, a lot of people here have very little scientific background and it's sufficient to just focus on the so-called "central dogma" of genetics for the purposes of this discussion.

And that's provided by molecular genetics -- whether or not one ascribes conscious agency to it.

Mutation is not random. It's probabilistic. But even if it were 100% totally random, that's fairly unimportant: the real issue behind selection as one (of several) mechanisms of population genetic evolution is that mutations are not preserved randomly, even if they arise randomly.

Also, again, realize that when one mentions mutation, we are really talking about allelic or haplotype polymorphisms -- these may be single nucletoide polymorphisms, they may be crossovers, they may be duplications, deletions, etc. There are lots of alterations in gene sequence that get lumped together as mutation here.

Just kidding friend. I certainly did not mean to suggest that all science is bad or driven by personal agenda. What I refer to is a human ego problem, and not directed at any one group over another. My sincere apology if I have offended you. It is the human propensity for fixity of assumptions that concerns me. That being a dogmatic trap to those who cannot release themselves from it.

Darwin never mentioned it. The concept was "born" out of a desire to identify a mechanism for natural selection to act upon. And no, absolutely not, most current scientists do not "sum evolution up as random mutation". It pleases me greatly to see (what I call) NeoNeo Darwinism downplay the role of randomness in light of new discoveries. Classic Darwinism (sans random mutation) is therefore reinforced.

Well, the fundamental principles may be solid, but the intricacies of the theory have evolved, like any other theory has, does, will, and should. How to best distinguish this evolution without rebranding? Isn't that a fundamental principle of evolution, to rebrand (note the change) of when mutations arise?


Dave Allen;106618 wrote:

Perhaps at the beginning, as taught to her from others. But her recognition is not from running with the pack of the times, under the "assumption" of "randomness". Her recognition is attributed to her evolving beyond those assumptions.

I never said that. You've misread me. I don't know of any "external" intelligence reference ever made from Barbara McClintock.

"Over the years I have found that it is difficult if not impossible to bring to consciousness of another person the nature of his tacit assumptions when, by some special experiences, I have been made aware of them. This became painfully evident to me in my attempts during the 1950s to convince geneticists that the action of genes had to be and was controlled. It is now equally painful to recognize the fixity of assumptions that many persons hold on the nature of controlling elements in maize and the manners of their operation. One must await the right time for conceptual change".
Barbara McClintock
Barbara McClintock - Wikipedia, the free encyclopedia

The fixity of assumptions she refers to are from those who were threatened by her discovery of controlled mutations. Those who's research was founded around an ill conceived (and heavily funded) concept random mutation.

I think Aedes just did by citing probables.

But if you like - a dice provides a certain number of results that are as likely or not as one another (or maybe not if it's poorly cut).

So there's a random factor in there - you can't predict the result even if you can guess at it.

But it isn't pure chaos - you'll get a number, or maybe a sexual position or something depending on the dice - I dunno. But you won't get chaos, despite the random factor.

The random factor's influencing the changes in DNA from the moment it splits to the moment it recombines are greater than those of a dice (any dice we could feasably make anyway).

So it's random in the sense of not knowing what the results will be.

But it's not chaos in the sense of the results might be anything, or are ungoverned by factors that limit them to set types, or that you can't say what they might be with some insight or general confidence.

Quote:

Very possibly. There was some talk on another thread of basing some metaphysical beliefs on her research. I'm possibly being unfair to her to claim she was responsible for such a thing herself, the testimony on that thread is pretty doubtful after all.

So if you aren't proposing the interferance of external intelligence I apologise for assuming you did.

However, even transposition results in some unpredictability, and may itself have arose out of natural selection of earlier processes that were even more unpredictable.

To be random means that all possible outcomes have equal probability, at least when "random" is not being used colloquially.

In its colloquial use, it's often interchanged with chaos, i.e. unpredictability.


By analogy, think about car accidents. Car accidents are a great example of chaos. At the beginning of the day, you cannot predict which two cars will collide with one another at the end of the work day, 10 hours later. The number of initial variables is too great, and the outcome partially dependent on so many of them. This is the so-called "butterfly effect".

But car accidents are NOT random. Elderly drivers, teenage drivers, males, distracted drivers, drunk drivers, speeders, etc are all more likely to be in accidents than sober, middle aged soccer moms driving the speed limit with their kids in the back. In other words, not all cars are equally likely to be in a collision.

It's certainly possible to do if you have parental DNA as a reference.

That is not an explanation, that is an observation. It assumes all the terms that are in need of explanation - 'create', 'new' and 'evolve' for example.


Orthodox Hindu answer from neo-vedanta viewpoint (as I understand it): What is 'latent' in the example I gave is Brahman as 'the cosmic intelligence'. In Indian philosophy it is not 'the universe' that is creating 'all this' (because, apart from anything else, 'all this' simply is the universe). 'All this' is actually a grand cosmic spectacle which the Brahman emanates for no particular reason (or just because he can) as Lila, the divine play. And the point of it is, not to simply to understand the concept, but to transcend our entrapment in it through 'vidya' or right knowledge, which is the culmination of the various paths of Hindu yoga.

But anyway all these kinds of ideas, whether Hindu, Christian, or Transylvanian, are anathema to materialism. That's what Daniel Dennett in Darwin's Dangerous Idea, Carl Sagan in Demon-Haunted World and Dawkins in The God Delusion are arguing so fiercely against. Don't scientists want to be able to reduce or explain everything we see to one or another intelligible algorithm? Isn't this what natural selection + mendelian genetics is supposed to be doing? So what need is there for a cosmic intelligence in this picture?

But we are still left with a great many imponderables. I think the situation in regards to the materialist philosophy of science, is that they are questioning really whether there is any order at all beyond what their own intelligence is capable of discerning, and in so doing, cutting the ground from under their own feet. This I think it why they (and I don't think anyone here is doing this) give the concept of 'randomness' such centrality in the scheme of things. It is not only believed, but truly important, that nature is dumb. I really believe that this kind of 'scientific atheism' is actually deeply irrational, so forgive me for a rather extended quote from Sufi scholar Henry Bayman (in an analysis of Neitszche and Hume and their attitude to 'the cosmic order')

Quote:
[INDENT]Thus, the denial of God has driven Nietzsche to deny science, the laws of nature, the existence of order and even of causality. There is no purpose in the world, only chaos. Instead of "law," Nietzsche substitutes "necessity." But what is this but another name for "law"? Likewise, biologist Jacques Monod, in Chance and Necessity (1971), denied the purposefulness implied by "teleology" only to exchange it with an almost identical word, "teleonomy." What is gained by substituting one word for another if both are intended to describe the same thing?

Now it is interesting to note that Nietzsche is not alone in the conclusions he reaches. Before him, David Hume trod the same path, and in his efforts to deny God did away even with the connection between cause and effect. Thus, as Professor Jacques Barzun notes, Hume arrived at a distrust of science and religion alike: "Hume's last word of doubt on religion carries with it such a doubt about the mind of man that the certainty of science goes down in shipwreck too." It was Kant who, transcending Hume, slipped a fresh foundation under the work of science.

Strikingly, we find the same attitude in Nietzsche. In The Will to Power, he states: "the psychological necessity for a belief in causality lies in the inconceivability of an event divorced from intent... The belief in [causes] falls with the belief in [purpose]." Thus the denial of God leads to the denial of causality, the basic underpinning of science. The world is not an organism, it is not even a machine. Even grammar does not escape his attacks, for it is a system of rules, order, and the repository of a hidden belief in causality.

Why? Why do both Hume and Nietzsche, in their overzeal to deny God, end up debauching science as well? Because their denial of God is dependent on the denial of any order whatsoever in the universe. Because they knew that science took its origin, and is still based on, a world in which order prevails. If the world is chaos, there can be no order, and hence no laws either of nature or of science. (In our day, however, even the word "chaos" is being redefined, as mathematicians and scientists discern hidden order in chaos.) For the existence of any kind of laws presupposes a Lawgiver, and indeed the originators of modern science-Newton, Descartes, Leibniz, etc.-quite openly expressed their faith in a Divine Lawmaker. In order to deny the latter, Hume, Nietzsche, and those who follow their path must deny the existence of any kind of order at all. But without such order, the whole enterprise of science falls down, for it is then senseless to seek for laws, order or pattern in a disordered world. Nietzsche borders on Orwellian Newspeak in his implied conclusion: "truth is a lie," and falls into the same rut that he so despises in those who confuse mortality and immortality. Yet paradoxically, Nietzsche was also genius enough to recognize that his nihilistic teaching (and Zarathustra's) is a "rebound from 'God is truth' to the fanatical faith 'All is false'."

But is all this true? "By their fruits you shall judge them." Science works-it is the most successful enterprise in the history of humanity. Even chance, even probability, has its laws and is not chaos. In that case, it makes sense to view the world as ordered, a place where laws-laws of science, laws of nature-hold. So it makes sense, in turn, to talk about a Lawgiver-which Newton, Copernicus, et al. had told us right from the very beginning, and which we would never have lost sight of had we not extended our debunking of the Christian conception of God to God Himself. The alternative is to assume that we ourselves project order onto the universe, which is a form of solipsism. In that case, though, the basis for an objective universe and materialism collapses. Even granting the point of solipsism, however, if man finds meaning within himself, where does he dredge up this meaning from? For according to Sufism, God is both Within and Without, so that we approach God even when we go within. God is both transcendent and immanent. Contrary to what Nietzsche thought, He is not just incarnate in Jesus, and not just beyond the universe.

Yes and it is perfectly true that you do not characterise the outlook that I am talking about...

As to 'why', that is a very interesting question and one that I have spent a lot of time contemplating. And I think it is historically determined, if you look at the specific historical and cultural origins of the rise of materialism in the European Enlighenment, and the rejection at that time of religious authority....although now it has gone much further than that, as Bayman notes, not just the rejection of religious authority but the whole idea of anything spiritual...but as we both know, you can be scientific without being materialist (and visca versa) and besides, the times they are a'changin, I think you're correct and the materialism of Dawkins, Dennett, Wilson is on the wane..perhaps it is, as Hegel foresaw, it is all part of a dialectic....

Well, I am. Barbara isn't, but I am.

I do not suggest that everyones individual DNA must be authored externally. That may or may not be the case and I have no position on that at all ([SIZE="2"]well, I am actually starting to plum for the internal intelligence[/SIZE]]). I'm suggesting sentient authorship for the genesis source of information. The code that got it all started.

Computer Science and A.I. are full of examples where code may sense, react, adapt, modify and re-author its own programming, with no external sentient intervention. But in all cases, the program must be sentient designed to do this from the very beginning.

Thanks for the explanation of random vs chaos. It makes perfect sense and I embrace the reasoning behind it.

I'm still in the middle of my move, but I did get the computer I needed set up. Not much time to enjoy our conversation, but I wanted to pass along that Russian research I mentioned earlier. I would love to get your impressions on this.

And thank you kindly for the excellent explanation of random vs chaos. I'm pleased to see a clear separation between the two.

Going to sleep now Wink

To be random means that all possible outcomes have equal probability, at least when "random" is not being used colloquially.

In its colloquial use, it's often interchanged with chaos, i.e. unpredictability.

By analogy, think about car accidents. Car accidents are a great example of chaos. At the beginning of the day, you cannot predict which two cars will collide with one another at the end of the work day, 10 hours later. The number of initial variables is too great, and the outcome partially dependent on so many of them. This is the so-called "butterfly effect".

But car accidents are NOT random. Elderly drivers, teenage drivers, males, distracted drivers, drunk drivers, speeders, etc are all more likely to be in accidents than sober, middle aged soccer moms driving the speed limit with their kids in the back. In other words, not all cars are equally likely to be in a collision.


So - I might be stating the obvious - you have the minute and unpredictable changes being brought about by genetic variation, on the one hand, and on the other hand, 'selection' due to circumstances which favour some of them, ever so slightly. All well and good. But then, it is not really feasible to completely seperate the genotype (if that is the right word) FROM the environment. So the totality of the change is not really just with regards to the organism but the organism-in-an-environment. So even though with regards to this or that variation, or this or that particular species, you can isolate exactly what might have changed between this and an earlier form, in another sense, the change reflects nature itself, the universe at large. So in this perspective an organism is a function of nature, rather than something existing apart from nature.

I suppose this is a 'holistic' perspective. I don't know if I am saying anything, or not...

Well, it depends upon where you draw the line in the sand for what "nature" is allowed to represent.

If something does in fact exist, is it not appropriate to consider it as part and parcel of nature (that which is)? I reject the term "supernatural". I don't believe such a concept is even possible.

If a God exists, then it is perfectly natural for a God to exist. Nothing supernatural about it whatsoever. Yet most would not allow for this, as they most commonly reserve "natural" for that which consists of material energy/matter alone.

If that be the case, then all of life is beyond natural, and thus supernatural due to the third agent of immaterial information required for its existence.

So which is it, natural as energy+matter alone as non-life, or natural as energy+matter+information as life?

There are some shocking inaccuracies in that reference, things that would be obvious even to an undergraduate student in biology. Their bolded statement "The genome (total sum of all genetic material) of an organism cannot consist of 98% garbage. This is nonsense from the perspective of evolution, which throws away anything unnecessary." is absurd. Evolution does not "do" anything -- unnecessary genes are only lost if they are deleterious. They completely neglect that some of that 98% of noncoding sequences are regulatory or code for functional RNA segments (other than mRNA). Their statement about embryology is wholesale ignorance ("some of these proteins are synthesized in one place of an organism, while their action in the form of a command is immediately expressed in another place of the embryo separated from the first one by hundreds of cells. There is no explanation for this immediate distant transmission of the command.") There is outstanding research (and has been for at least 20 years) on protein gradients within oocytes, so that even an unfertilized egg already has polarity -- dorsal/ventral, cranial/caudal, and lateral polarity. Thus, when a fertilized egg divides for the very first time the cytoplasm of the daughter cells differ from one another. This leads to asymmetrical gene regulation. It may be that maternal helper cells are directly trafficking mRNA transcripts into oocytes, and these are translated within the oocyte to create protein gradients of genetic regulatory elements. The Homeobox genes are the most famous, but there are others (I worked on the bicoid gene when I was an undergrad, about 15 years ago).

So the very premises of the article display a striking lack of accuracy. The rest of it is essentially unreferenced, certainly not basing any substantial part of the text on research that's made it to a refereed journal (and with all due respect to Russian science, which is perfectly fine, the best research from anywhere in the world goes to English language journals because they have the strictest standards and largest readership).

Thanks so much for taking the time with that. Your assessment is valued, worthy of deep consideration.

True, and this is in part because DNA is nothing without regulation of its expression, and environmental cues can either directly modify DNA expression, or set in motion physiologic processes that in turn regulate expression.

But, jeeprs, even if these things aren't completely separable, that doesn't change the fact that the genome (of one organism), the genome (of a species), an organism, a population, are 'discrete' enough that you can study and understand them unto themselves too. This is particularly relevant when you can study lots of examples in lots of conditions (think of medical research), or you can study something in a lab with totally controlled conditions (think of a lab rat or a bacterial culture).

Nonetheless, the take home message for evolutionary biology is that selection acts on function and not on sequence, i.e. whether it's the structure of a gene product or if it's simply the amount of the same gene product, it's this end effect that matters in the end however it's achieved.

[large red flashing light icon]....God 'exists' - if God exists - in a completely different way to the way in which material objects or persons exist. But I think to discuss this requires some concept of the 'hierarchy of being' which I don't think is part of the modern, or scientific, lexicon. Probably not the thread to discuss theology though.

But I don't think these two perspectives - focussing on the individual in particular, or as part of a larger whole, are contradictory. One is more 'holistic', that is all - kind of an environmentalist's perspective. A considerable part of the modern angst can be overcome by overcoming one's sense of alienation from nature. I rather like the idea of nature becoming articulated via living organisms.
