Well, no one "knows," but that wasn't the question. The question was do you believe it's possible?

@Thomas,

DNA probably evolved from RNA....RNA, in turn, very likely evolved from simpler replicators still.


Easy to say, and easy to believe, if you're so inclined. Everything that supports one's preferred conclusion always seems "probable" (if not virtually certain), as a matter of course. As previously noted, there are dozens of mutually exclusive hypotheses about how abiogenesis could occur. All raise serious questions of consistency with what we do know. To quote one scientific critic of the RNA world hypothesis:

Quote:
Joyce and Orgel further argued that nucleotides cannot link unless there is some activation of the phosphate group, whereas the only effective activating groups for this are "totally implausible in any prebiotic scenario", particularly adenosine triphosphate...Joyce and Orgel proposed to reject "the myth of a self-replicating RNA molecule that arose de novo from a soup of random polynucleotides"[56] and hypothesised a scenario where the prebiotic processes furnish pools of enantiopure beta-D-ribonucleosides.


https://en.wikipedia.org/wiki/RNA_world

But, as Leddy noted, none of the theories even address the issue of where the information comes from. They are strictly confined to an attempt to reconstruct the physical components of self-replicating life.

To say: "It was probably like this, but all the evidence has been destroyed," sounds like a "faith-based" conclusion, eh?

@layman,
I left out this part, eh?
Quote:

"Molecular biologist's dream" is a phrase coined by Gerald Joyce and Leslie Orgel to refer to the problem of emergence of self-replicating RNA molecules, as any movement towards an RNA world on a properly modeled prebiotic early Earth would have been continuously suppressed by destructive reactions.

Joyce and Orgel specifically referred the molecular biologist's dream to "a magic catalyst" that could "convert the activated nucleotides to a random ensemble of polynucleotide sequences, a subset of which had the ability to replicate".


So what's wrong with magic, I ask ya? How else ya gunna explain it all? And what's wrong with dreams? I hear-tell that sometimes they foretell the future.

This whole idea of DNA "evolving" is one that lead Crick to reject the whole idea of the DNA code developing on earth. If the code itself is subject to 'mutation" and evolution, he asked, then why does every living species have exactly the same code after 4 billion years? We could only expect to see many different codes, but we don't.

Why is there this incessant interpretation of the word "intelligence" as meaning God? Those are two radically different things, aint they? This treatement of "intelligence" as a synonym for God is absurdly over-simplified. I can't see any reason whatsoever for it. Quoting the notorious ID'er, Stephen Myers here:

Quote:
Q: It seems like the idea or inference of anything supernatural scares scientists away. Do you agree?

A: Well, all we are inferring is intelligence. Whether it is supernatural or natural is a matter for further deliberation. I don’t even like the term “supernatural.” I think the better philosophical distinction is between transcendent and immanent. Are we talking about an intelligence within the cosmos or an intelligence that is in some way beyond it? And that’s a theological distinction. I think it is possible to reason about that, and whether you call it a philosophical deliberation or not, it doesn’t really matter. All the theory of intelligent design is doing is establishing that intelligence was responsible for certain features of life. We recognize intelligence all the time, and we have scientific methods for it. If you’re an archaeologist and you’re looking at the Rosetta Stone, are you duty-bound to continue looking for naturalistic explanations even though you know full well that wind and erosion and everything else you can imagine is not capable of making those inscriptions? No, you’re not. You really ought to conclude the obvious, which is that a scribe was involved. There was an intelligence behind it.


http://magazine.biola.edu/article/10-summer/can-dna-prove-the-existence-of-an-intelligent-desi/

Using Myer's distinction, there is a huge difference between transcendent intelligence and immanent intelligence.

I have to admit that Im unaware of the mountains of research thats going on in ID. Can you fill me in?


I aint go no clue neither Farmer, but if you really want to know (I'm sure you don't) here's what Myers claims:

Quote:
In the back of Signature in the Cell I lay out the research program of ID and an appendix that develops 10 key predictions that the theory makes. There’s a new journal called BIO-Complexity that is investigating the heuristic fruitfulness of intelligent design. It’s testing the theory, looking at papers that generate predictions based on the theory, publishing papers that are developing new lines of research based on the theory.

To the point that it’s mainly a negative enterprise — that is completely incorrect. ID is proposing an alternative explanation of life. It’s not just criticizing Darwin or criticizing chemical evolution; it’s proposing a contrary explanation and in light of that explanation, developing a number of important hypotheses that can be tested in a laboratory.


So, if ya wanna know....

@layman,
Personally, I tend to agree with the comments of this poster on the site previously linked:

Quote:
Even if there was an intelligent designer (which I highly doubt, but ID is still valid as a theory), there is no reason to believe the designer (or designers) were anything like any of the "gods" conjured up by man -- the Christian version or otherwise...even if intelligent design could somehow be proven, it still doesn't guarantee that a "god" did the deed.

And yes, I will read his book. I'm ready to be convinced if his argument is sound, but this interview doesn't give me much hope. Again, I don't dismiss the idea of intelligent design as a remote possibility for how life came to be, but I am disappointed in people who employ its scientific branding towards justifying their own shoddy entrenched belief systems.


Ya gotta give the guy credit for being willing to read the book, rather than just sneer at it based on a dogmatic ontology, eh? It sometimes amazes me to see how much most people, including those who style themselves as empirical scientists, think they know, for certain, a priori.

It seems that some scientists believe there is immanent (not to say transcendant) intelligence in the cosmos, eh?

Why Physicists Are Saying Consciousness Is A State Of Matter, Like a Solid, A Liquid Or A Gas

There’s a quiet revolution underway in theoretical physics. For as long as the discipline has existed, physicists have been reluctant to discuss consciousness, considering it a topic for quacks and charlatans. Indeed, the mere mention of the ‘c’ word could ruin careers.

That’s finally beginning to change thanks to a fundamentally new way of thinking about consciousness that is spreading like wildfire through the theoretical physics community. And while the problem of consciousness is far from being solved, it is finally being formulated mathematically as a set of problems that researchers can understand, explore and discuss.

Today, Max Tegmark, a theoretical physicist at the Massachusetts Institute of Technology in Cambridge, sets out the fundamental problems that this new way of thinking raises....Tegmark’s approach is to think of consciousness as a state of matter, like a solid, a liquid or a gas. “I conjecture that consciousness can be understood as yet another state of matter. Just as there are many types of liquids, there are many types of consciousness,” he says.

Interestingly, the new approach to consciousness has come from outside the physics community, principally from neuroscientists such as Giulio Tononi at the University of Wisconsin in Madison.

In 2008, Tononi proposed that a system demonstrating consciousness must have two specific traits. First, the system must be able to store and process large amounts of information. In other words consciousness is essentially a phenomenon of information.

And second, this information must be integrated in a unified whole so that it is impossible to divide into independent parts. Both of these traits can be specified mathematically allowing physicists like Tegmark to reason about them for the first time. He begins by outlining the basic properties that a conscious system must have...

Sounds a little like Meyers and other ID'ers are trying to do with math, etc., eh?

Certainly, but I hope it can be honestly presented in a means that recognizes that for anything thats going on in this research, it has certainly not risen to any level of "theory". Thats a bit much. Its almost like that TV show "ANCIENT ALIENS" wherein, these guys who believe that aliens made us, gave us fire , toothbrushes, and color tv are called "Ancient Alien Theorists".

I am a bit irascible and impatient with "theories" like that youve clipped wherein the authors start with a given and then, through mathturbation, prove it was reasonable.

SCience , has for years, recognized that specific chains of physical and physical-chemistry reactions seem follow exclusive and fixed sequences, all over the world . These are chemical and physical imperatives. They are well unerstood.

Its not "incessant". It was the original "MISSION STATEMENT" of the Discovery Institute when it began as a Fundamental Christian Organizatiion after the Edwards v Aguillard. It has merely changed its focus by "Degodding" its huckster language for folks like some here who seem to deny the organizations history as an outgrowth of the Institute for Creation SCience then they and claim that they dont concern themselves with that "religious stuff". They are only interested in pure science(In a rats ass, I say)

History needs to be respected so we dont have to relive the messes of the past.
I like discussing these matters with you (although you seem to be brief on your own understandings and long on clips that "recite" dogma). However, I havent changed my own opinion that you are like a few other "true believers" weve had here in the past years.

So what? As usual, Farmer, you refuse to address the point, and simply re-assert your strongly-held animosities. Forget what THEY were trying to do. Is that possible, for you? It seems not. You always reduce this to some us against them ideological battle.

BTW, when you start mindlessly quoting various authors and "Scientists" you should know of whom you speak. It wasnt PZ Myers of whom you were speaking (even though that's who , by misspelling, was the authority youve tried to invoke).

The "other guy" is STEVEN C. MEYERS (totally different) who has been a long time IDer who lived through the "degodding" of the Discovery Institute, and probably had a hand in that gag. In fact, SC MEYERS helped set up the Center for SCience and Culture and was a prime author of the Discovery Institutes "Wedge Strategy" .

BTW, he was hozking for a new ID magazine (thats so DI could probably claim more "peer review")

There are reputable scientists who believe that all matter has "consciousness" in varying degrees. So far as I know, they don't apply that to fundamental forces, like gravity, but rather to structures of matter.

Integrated Information Theory (IIT), which has become quite a hot topic in contemporary neuroscience, claims to provide a precise way to measure consciousness and express the phenomenon in purely mathematical terms.

The theory was put forth by psychiatrist and neuroscientist Giulio Tononi, and has attracted some highly regarded names in the science community. One such name is Christof Koch, Chief Scientific Officer at the Allen Institute for Brain Science, who now champions the idea along with Tononi. Koch may be best-known for bringing consciousness research into the mainstream of neuroscience through his long-term collaboration with the late DNA co-discoverer Francis Crick.

Christof Koch's answer: Consciousness is a fundamental property of the universe. Wherever there is integrated information, there is experience.

Koch writes: "Even simple matter has a modicum of Φ [integrated information]. Protons and neutrons consist of a triad of quarks that are never observed in isolation. They constitute an infinitesimal integrated system."

Koch goes on: "The entire cosmos is suffused with sentience. We are surrounded and immersed in consciousness; it is in the air we breathe, the soil we tread on, the bacteria that colonize our intestines, and the brain that enables us to think."

IIT turns out to be a modern twist on an ancient philosophical view known as "panpsychism". But before you go dismissing the concept because of its name, you should know that intellectual heavy hitters such as Baruch Spinoza, Gottfried Leibniz, and William James are all considered panpsychists. Its central tenant is that all matter has a mental aspect, which makes consciousness universal.

No, Farmer, you are just being a pig-headed fool who can't cope with any nuances, including those which Meyers himself makes rather articulately.
