"To grasp the reality of life as it has been revealed by molecular biology,
we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalelled complexity and adaptive design. On the surface of the cell we would see millions of openings, like port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity... (a complexity) beyond our own creative capacities, a reality which is the very antithesis of chance, which excels in every sense anything produced by the intelligence of man..."

- W.H. Thope. Cambridge Professor of Zoology

Another gem from the same thread, by onyerbike :

Alasdair Noble has written a pretty sensible article. However intelligent design or Intelligent Design seem to mean different things to different people.

The trouble is that we have three quite different disciplines overlapping in this debate about origins:

Natural Science deals with the repeatable regular material level of things only

Philosophy perhaps is the most apposite discipline for arguing about nature and order in the universe, and what it implies.

Theology comes in with divine revelation about the role of the Creator in fashioning the material Universe.

A number of the commentators on this blog have only scorn for anything other than what they imagine to be natural science. Contemnunt quod non capiunt.

Whether evolutionary biology is a true science in the sense of physics and chemistry is a moot point. It is really a form of biological archaeology, with a great deal of surmise and theorising thrown in. You can't repeat the 2 billion year experiment of evolution upon earth.

Those who - for their own private reasons - adopt a philosophical stance of atheism or materialism, are left with evolutionism as their only mechanism for explaining the origin of life, and tend to cling to it with a faith far greater than that of most religious believers. They insist upon it and hurl venom and vitriol at anyone who questions it.

Those who hold to a theistic position, have no trouble in accepting that a Creator may well have operated by evolution, by designing the language of DNA, and perhaps by helping the process over some high negative entropy and statistically extremely unlikely steps.

To my mind the big gaps seem to be:

How were the building blocks of life - RNA, DNA - assembled, and in the amino-acid rich ambience required, and in an oxidising atmosphere? This is a pre-evolutionary question, because evolution couldn't have started at this point of mere chemical assemblages.

Where did the biological info input of the DNA code come from?

The history of evolution is far from a smooth steady advance. There are catastrophes, there are other periods of rapid development - pre-Cambrian explosion etc. Moreover, macro-evolution has not really been observed in th laboratory, though micro-evolution is. Why is the rate of evolution not constant but goes in odd very intense periods interspersed by very long geological periods of species stability?

The irreducible complexity arguments of Behe and others like him seem very difficult to answer, at least to someone with a Cambridge PhD in organic chemistry like me.

It is very wrong, I think, to insist that evolution is a proven fact, when there are so many unanswered questions as to how it may have worked. We need to know a lot more about how changes in the genetic code relate to changes in physical build, before we can be so dogmatic. If we facilely assert that evolution is proven, we will not investigate properly and scientifically the difficulties in its path. True science will suffer at the hands of an evolutionist dogmatism. .

Pfft. Ending everything with "God did it" will kill scientific endeavor faster than anything else.

6. Viruses mutate and adapt all the time...
What is he talking about evolution not being observable.

And those viruses evolve in reaction to a threat or an opportunity.

I know viruses are different in structure than a living cell, but if a viruses can "adapt" to a threat or opportunity, why can't living cells?

Btw, I know a living cell might not be the term to use, but it is the only term I can think of to compare it to a virus which, we are told, is different from normal cells or living cells...

4. ID = Magic
I wish magic was real too. ID can not be science. It does not explain who designed this alleged designer. Only magic can explain it. It is based on magic.

5. Behe is a moron.
You need look no further than the Dover trial in 2005.

Herman Muller showed that irreducible complexity is a prediction of evolution. Using it as an argument against evolution is little more than an argument from ignorance.

7. "To my mind the big gaps seem to be"
Yeah, well, your mind is rather uneducated bub.

How were the building blocks of life - RNA, DNA - assembled, and in the amino-acid rich ambience required, and in an oxidising atmosphere?

Uh, because they weren't. #1, no one says that the RNA or DNA molecules just self-assembled as they exist today from individual atoms. #2, Earth's early atmosphere had little to NO oxygen. It didn't come about until the first lifeforms started making it as a WASTE PRODUCT.

Where did the biological info input of the DNA code come from?

Begging the question.

Why is the rate of evolution not constant but goes in odd very intense periods interspersed by very long geological periods of species stability?

This person has obviously not studied ANY modern evolutionary theory and instead (like most Cretinists) assumes that what Darwin wrote is the be-all, end-all summary of all that is known about evolution.

The irreducible complexity arguments of Behe and others like him seem very difficult to answer

Really? The talk.origins website has a number of demolitions of Behe's claims right here.

Basically the whole creationist / "intelligent" "design" argument is the one from personal incredulity (with a healthy portion of ignorance).

12. "personal incredulity" -- hits the nail on the head.
Edited on Fri Dec-04-09 12:30 AM by eppur_se_muova
Some people are overwhelmed by the complexity, so they assume everyone else should be too. DOES. NOT. COMPUTE.

Your remarks were very concise and to the point. Quite evidently you've kept up with the science better than a certain Cambridge PhD in organic chemistry. You'd think this guy had never done any reading about prebiotic chemistry.

ETA: a quick Google on "prebiotic chemistry" gives some idea on how much research has been done in this field, and just how complex the systems being studied have become since this field began.

13. actually they DO say...
"#1) no one says that the RNA or DNA molecules just self-assembled as they exist today from individual atoms."

They DO say that, and I personally believe that is what happened. Amino acids form naturally in space and on earth. RNA is composed of amino acids, phosphate, and ribose. The current accepted hypothesis for the origin of life is RNA that "spontaneously" self-aggregated.

14. Key words: "as they exist today"
Creationists basically want to look at a modern-day living cell as their "example" of how life should have begun. It should be noted here that they are conflating two different subjects (evolution and abiogenesis), but regardless, the very first self-replicating molecule in the muck was most definitely not the RNA or DNA we have in our cells today. But that's what they think it SHOULD have been for evolution to be true at all.

15. this happens all the time in my Bio class
"they are conflating two different subjects (evolution and abiogenesis)"

some students cant believe that life spontaneously formed in a chemical soup so they dismiss all evolution. very sad.

"the very first self-replicating molecule in the muck was most definitely not the RNA or DNA we have in our cells today"

correct. the first "life" was presumably "RNA-like" with a handful of amino acids. It needed enought to catalyze a reaction, but certainly not the dozens or hundreds of base pairs we find in our RNA today.

11. We can watch evolution on a microbiological scale in real time.
We even set up experiments to make microbes evolve the way we want them.

Evolution has been documented in living species of insects.

Recently, on this board, there was a story where scientists documented speciation (that would be evolution from one species to another) in birds on Galapagos, complete with photographs.

We have documented evidence of thousands of local mutations in the human genome (one being dryer earwax among in eastern Asian populations) that shows we humans are evolving.

Unless you can measure out a pound of God or an ounce of Deity, there is no room for intelligent design or other fantasies in science.

Religion holds many comforts for many people, but it holds nothing for science except a broadening of ignorance.

Edited on Fri Dec-04-09 02:53 PM by Joe Chi Minh
character, all sorts. Why even these guys agree on that, at least in relation to more recent times, but there's an awful lot more to it, apparently, so that they are now talking about an Extended Evolutionary Synthesis:

'Suzan Mazur, Scoop, NZ, July 10 It's not Yasgur's Farm, but what happens at the Konrad Lorenz Institute in Altenberg, Austria this July promises to be far more transforming for the world than Woodstock. What it amounts to is a gathering of 16 biologists and philosophers of rock star stature - let's call them "the Altenberg 16" - who recognize that the theory of evolution which most practicing biologists accept and which is taught in classrooms today, is inadequate in explaining our existence. It's pre the discovery of DNA, lacks a theory for body form and does not accommodate other new phenomena. So the theory Charles Darwin gave us, which was dusted off and repackaged 70 years ago, seems about to be reborn as the "Extended Evolutionary Synthesis".

Papers are in. MIT will publish the findings in 2009 - the 150th anniversary of Darwin's publication of the Origin of Species. And despite the fact that organizers are downplaying the Altenberg meeting as a discussion about whether there should be a new theory, it already appears a done deal. Some kind of shift away from the population genetic-centered view of evolution is afoot. . .'

And here is more interesting information you will not find to your taste:

'Suzan Mazur: Are there alternatives to natural selection?

Stuart Kauffman: I think self-organization is part of an alternative to natural selection. . . In fact, it's a huge debate. The truth is that we don't know how to think about it.

Suzan Mazur: You said in your forward to Investigations: "Self organization mingles with natural selection in barely understood ways to yield the magnificence of our teeming biosphere. We must, therefore, expand evolutionary theory."

Stuart Kauffman: I'm still there. . . .

Suzan Mazur: You've said: "The snowflake's delicate six-fold symmetry tells us that order can arise without the benefit of natural selection." So it can arise without natural selection, but it's not living.

Stuart Kauffman: But it's not living. Right. There are all sorts of signatures of self-organization. I'll give you one that very few would doubt. . . If you take lipids like cholesterol and you put them in water, they fall into a structure - a liposome, which is called a bilipid membrane, that forms a hollow vesicle. . . . Now if you look at the structure of this bilipid membrane, it's virtually identical to the bilipid membrane in your cells. So this is a self-organized property of lipids. That's physics and chemistry. . . . And evolution has made use of it to make lipid membranes that balance cells. So that's a snowflake. It's hard to look at that and doubt it. Nothing mysterious or mystical. . .

Suzan Mazur: No genes in the mix.

Stuart Kauffman: Genes by themselves are utterly dead. They're just DNA molecules. It takes a whole cell in the case of a fertilized egg to grow into an adult. So there's a lot of physics and chemistry. . . . And somehow the right answer is that this is a whole integrated system in which matter, energy, information, whatever that means - it turns out to be a very slippery concept - and the control of process is all organized in some way. . .
Suzan Mazur: So natural selection exists throughout the universe?

Stuart Kauffman: Well, yes, wherever there's life. But notice that there's self-organization too. . .

There are people who are spouting off as if we know the answer. We don't know the answer.

Suzan Mazur: So you're saying we should enjoy life.

Stuart Kauffman: Well, we should enjoy life. But we have to rethink evolutionary theory. It's not just natural selection. Self-organization is real.'

http://www.scoop.co.nz/stories/HL0807/S00214.htm

Yet there is no rational alternative to Intelligent Design. Einstein, did't belieive in a personal God, yet was in absolute awe of what he called, '.... illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind.' Vegetable life, bereft as it is of intelligence, can neither organise themselves or select a robust partner to help them perpetuate the species. The agency responsible must be transcend the empirical, be omniscient and omnipotent.

Ironically (and topically), it's the Hidden Hand that the moral philospher, Adam Smith, was alluding to. In reality, he was simply iterating and commending the age-old Christian axiom that grace builds upon nature. 'All things work together for good to those that love God.' Don't scorn the activities of the suicidally worldly, rapacious businessman, use his lowly skills. But be very, very sure that you monitor his every action, as if by electronic tagging, because otherwise, he will be your master. And a very, very cruel and vicious one at that. We are all of us body as well as spirit. They can help us feed our bodies; with God's grace we can help nurture their spiritual nature. In the end, God has no favourites.

That was evidently what Smith meant by his Hidden Hand. He was contending against the Norman (norseman) aristocracy and upper-class, whose treasure derived from the plundering of other nations and their own British subjects; and they would have been envious of the merchants' endless capacity for capacity for money-making. Smith was saying that hobbling them in the ways the latter favoured was short-sighted. Don't throw the baby out with the bath-water.

But to revert to the "self-organisation" to which Kauffman refers, that still remains on the self-limiting path imposed by empirical science. They will need to go back to the original meaning of the word, 'science' as simply 'knowledge', incorporating the empirical bit wherever appropriate. Of course, atheists will cite the so-called 'God the Gaps', but that is very facile, since an omniscient and omnipotent God would necessarily be spared the limitations that entail gaps.

That emotional fixation you have with atheism is an intellectual cul-de-sac, and a very poor religion. The following article becomes heavy going, after a while, unless you're into the detailed complexity of philosophy at that level. But the blurb at the end of the article indicates the withering acerbity of her put-down of secular fundamentalism.

http://books.google.co.uk/books?id=3jUSU-r0lpMC&dq=Mary+Midgley&printsec=frontcover&source=an&hl=en&ei=5kDzSpjCM82hjAetkuWkDg&sa=X&oi=book_result&ct=result&resnum=6&ved=0CBsQ6AEwBQ#v=onepage&q=&f=false

Evidently, you would dismiss Galileo and Einstein as 'fundie' simpletons, because your penultimate sentence absolutely contradicts one of their most elementary axioms, best summarised by the latter: 'Not everything that can be counted counts, and not everything that counts can be counted.' The first article in the link below should give you a glimpse of the terminal limitations of Newton's mechanistic physics - limitations, that is, in terms of the frontiers of our research of the macro and microcosm. Quantum physics is pure magic, if my layman's understanding of such phenomena as 'ghost-like action from a distance' is any guide.

Strange, though, isn't it, that so many scientific break-throughs were achieved by men with a religious background. There seems to be an affinity between Christianity and empirical science, albeit at the rather higher level of inductive reasoning. Darwin majored in theology.

From Wikipedia:

'Darwin had to stay at Cambridge until June. He studied Paley's Natural Theology which made an argument for divine design in nature, explaining adaptation as God acting through laws of nature.'

'When exams drew near, Darwin focused on his studies and was delighted by the language and logic of William Paley's Evidences of Christianity.<21> In his final examination in January 1831 Darwin did well, coming tenth out of a pass list of 178.'

And this, again from Wiki:

'Gregor Johann Mendel (July 20, 1822<1> – January 6, 1884) was an Augustinian priest and scientist, who gained posthumous fame as the figurehead of the new science of genetics for his study of the inheritance of certain traits in pea plants. Mendel showed that the inheritance of these traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognized until the turn of the 20th century. The independent rediscovery of these laws formed the foundation of the modern science of genetics.'

Then of course there were Galileo and Newton:

Galileo Galilei (1564-1642) was a pivotal figure in the development of modern astronomy, both because of his contributions directly to astronomy, and because of his work in physics and its relation to astronomy. He provided the crucial observations that proved the Copernican hypothesis, and also laid the foundations for a correct understanding of how objects moved on the surface of the earth (dynamics) and of gravity.

'Newton, who was born the same year that Galileo died, would build on Galileo's ideas to demonstrate that the laws of motion in the heavens and the laws of motion on the earth were one and the same. Thus, Galileo began and Newton completed a synthesis of astronomy and physics in which the former was recognized as but a particular example of the latter, and that would banish the notions of Aristotle almost completely from both.

One could, with considerable justification, view Galileo as the father both of modern astronomy and of modern physics.'

http://www.google.co.uk/search?sourceid=navclient&ie=UTF-8&rlz=1T4ADFA_enGB339GB339&q=galileo+laws+dynamics

Rather pathetically, because of Galileo's confrontation with the institutional church of his day, atheists like to claim him as their own, but that is far from the truth. The truth is that, like Newton, he was what many would have called a 'religious nut'. It was only the influence of his powerful father tha prevented his joining the priesthood. Newton ended scorning mathematics and physics, albeit in favour of alchemy and a theology that doesn't seem to have made an impression then or now. But you'd have to agree, he was some physicist, and pretty smart.
