Round-up of stories about intelligent design, from the Discovery Institute

The Discovery Institute is the headquarters for ID research and advocacy in the United States. They send out a newsletter by e-mail and I though this week’s hit on all cylinders. Below are some of their stories from the newsletter. Thanks to commenter ECM for an earlier tip on the Junk DNA story.


When “Junk DNA” Isn’t Junk: Farewell to a Darwinist Standard Response

Richard Sternberg, research scientist at the Biologic Institute supported by the Center for Science and Culture, is now blogging at Evolution News & Views, weighing in on the latest research showing that so-called “Junk DNA,” which Darwinists have discounted as “rubbish,” are actually “anything but that.”

Sternberg writes:

In the Darwinist repertoire, a standard response to evidence of design in the genome is to point to the existence of “junk DNA.” What is it doing there, if purposeful design really is detectable in the history of life’s development? Of course this assumes that the “junk” really is junk. That assumption has been cast increasingly into doubt. New research just out in the journal Nature Genetics finds evidence that genetic elements previously thought of as rubbish are anything but that. The research describes tiny strands of RNA, previously thought to be junk, that now turn out to play a role in gene expression. Another finding by Dr. Geoff Faulkner shows that “retrotransposons,” a further variety of “junk” as the dogma previously taught, play a similar role.

Also at ENV, Dr. Sternberg takes a look at the old Darwinian tripe that biological systems couldn’t possibly have been designed because they exhibit “shoddy engineering”:

We often hear from Darwinians that the biological world is replete with examples of shoddy engineering, or, as they prefer to put it, bad design. One such case of really poor construction is the inverted retina of the vertebrate eye. As we all know, the retina of our eyes is configured all wrong because the cells that gather photons, the rod photoreceptors, are behind two other tissue layers. Light first strikes the ganglion cells and then passes by or through the bipolar cells before reaching the rod photoreceptors. Surely, a child could have arranged the system better — so they tell us.

The problem with this story of supposed unintelligent design is that it is long on anthropomorphisms and short on evidence. Consider nocturnal mammals. Night vision for, say, a mouse is no small feat. Light intensities during night can be a million times less than those of the day, so the rod cells must be optimized — yes, optimized — to capture even the few stray photons that strike them. Given the backwards organization of the mouse’s retina, how is this scavenging of light accomplished? Part of the solution is that the ganglion and bipolar cell layers are thinner in mammals that are nocturnal. But other optimizations must also occur. Enter the cell nucleus and “junk” DNA.

Jerry Coyne Recycles: Why Darwinism Is False

Jonathan Wells is reviewing Jerry Coyne’s Why Evolution Is True over at ENV, and already the list of problems with Coyne’s book is mounting:

On Earth Day 2009, we are reminded of the ecological importance of recycling. As a professor in the Department of Ecology and Evolution at The University of Chicago, Jerry A. Coyne must be keen on recycling: He even recycles worn-out arguments for Darwinism.

If “evolution” meant simply that existing species can undergo minor changes over time, or that many species alive today did not exist in the past, then evolution would undeniably be true. But “evolution” for Coyne means Darwinism — the theory that all living things are descendants of a common ancestor, modified by unguided natural processes such as DNA mutations and natural selection.

Coyne discusses the fossil record, embryos, vestigial structures, the geographic distribution of species, artificial and natural selection, and the origin of species. In the process, (1) he ignores the Cambrian explosion — which Darwin considered a “serious” problem — and he rearranges the fossil record to fit Darwin’s theory; (2) he defends Ernst Haeckel — who faked some drawings of vertebrate embryos to provide support for Darwinism — and he dredges up the doctrine that ontogeny recapitulates phylogeny; (3) he claims that much human DNA is useless junk — despite abundant recent evidence that this is not true — and he relies on theological arguments that have no legitimate place in natural science; (4) he invokes “the well-known process called convergent evolution” to explain many cases of the geographic distribution of species — even though the “well-known process” is merely speculation — and he again falls back on theology to justify a supposedly scientific theory; and (5) he describes examples of natural and artificial selection — none of which show anything more than minor changes within existing species — and he misrepresents experimental evidence to make it sound as though the origin of species by natural selection has been directly observed.

Other stuff

The newsletter also discussed historian A.N. Wilson’s return to faith from atheism, which is really interesting because he seems to be well-rounded in his reasons for rejecting atheism. And the newsletter mentions that Jay Richards’ forthcoming book, “Money, Greed, and God: Why Capitalism Is the Solution and Not the Problem” is out May 6th! Jay gave a great lecture on basic economics for Christians and another great lecture on what Christians should think about global warming.

How well do Darwinists do in debates with skeptics?

UPDATE: Welcome Post-Darwinist readers! Thanks for the link Denyse!

I thought that I would introduce a couple of my favorite critics of Darwinian fundamentalism, Stephen C. Meyer and Jonathan Wells. Here they are debating with Michael Shermer. I like Michael Shermer for two reasons – fiscal conservatism and engagement with his opponents. I’ve seen him MC sessions at Christian conferences. So let’s give him a chance to make his case.

Biographies of our debaters

Michael Shermer

Dr. Michael Shermer is the Founding Publisher of Skeptic magazine (www.skeptic.com), the Executive Director of the Skeptics Society, a monthly columnist for Scientific American, the host of the Skeptics Distinguished Science Lecture Series at Caltech, and Adjunct Professor of Economics at Claremont Graduate University. Dr. Shermer received his B.A. in psychology from Pepperdine University, M.A. in experimental psychology from California State University, Fullerton, and his Ph.D. in the history of science from Claremont Graduate University (1991).

Stephen C. Meyer

Stephen C. Meyer is director and Senior Fellow of the Center for Science and Culture at the Discovery Institute, in Seattle. Meyer earned his Ph.D. in the History and Philosophy of Science from Cambridge University for a dissertation on the history of origin of life biology and the methodology of the historical sciences. Previously he worked as a geophysicist with the Atlantic Richfield Company after earning his undergraduate degrees in Physics and Geology.

Jonathan Wells

Jonathan Wells has received two Ph.D.s, one in Molecular and Cell Biology from the University of California at Berkeley, and one in Religious Studies from Yale University. He has worked as a postdoctoral research biologist at the University of California at Berkeley and the supervisor of a medical laboratory in Fairfield, California, and he has taught biology at California State University in Hayward.

Massimo Pigliucci

Massimo Pigliucci, Ph.D., is a professor in the Department of Ecology and Evolution at State University of New York at Stony Brook, where he conducts research on the ecology of plant populations and the evolution of adaptations…. He received his doctorate in genetics at the University of Ferrara in Italy, his Ph.D. in botany from the University of Connecticut, as well as a Ph.D. in philosophy of science at the University of Tennessee.

Let’s get ready to rumble!

Let’s start with a short 15-minute debate between Michael Shermer and Stephen Meyer, moderated by Lee Strobel.

Meyer starts with these points:

  • the origin of the universe implies a Creator who exists outside of time, space and matter, because he created time, space and matter
  • the physical constants and ratios of physics must be fine-tuned in order to support the minimal requirements for life
  • the cell is filled with molecular machines that are identical to machines built by humans, such as rotary engines
  • the cell contains biological information in the DNA, and the origin of this information cannot be explained by evolution

Shermer makes these points:

  • we should never infer intelligent causes, we should keep searching for a materialistic explanation and say we don’t know until we find an explanation that allows me to continue to be an intellectually-fulfilled atheist
  • who made the designer?
  • maybe the big bang will be overturned and then we can go back to the eternal universe that I want to be true in spite of the evidence
  • we can speculate (without any experimental evidence) about alternative theories of how the universe got here, unlike the standard big bang theory which is backed by multiple lines of scientific evidence

Then a dialog ensues:

Shermer: The design of life is sub-optimal – if God did it, it should be perfect, with no trade-offs between non-functional requirements, just like Wintery Knights’ software architecture designs and Java code are perfect

Meyer: There is no such thing as a perfect design. Software architects, like Wintery Knight, who have studied software design, will tell you that non-functional requirements must be traded-off against one another. (Source: Software Engineering Institute at Carnegie Mellon University)

Shermer: Let me commit the ad hominem fallacy by attacking the motives of intelligent design proponents instead of dealing with their arguments and evidence.

Meyer: Two can play at that game, since evolutionists are atheists and secular humanists. But who cares? let’s stick to the arguments and evidence, ok?

Strobel: Meyer, are evolution and Christianity compatible?

Meyer: No, because evolution requires that the natural processes that create the diversity of life be random and unpredictable.

Shermer: Well, maybe the natural forces could be caused by the designer but in a totally undirected and undetectable way, so you Christians could have blind faith and we could run the public square.

Meyer: But Darwinism says and that no design is detectable in those processes, so they processes cannot be actually directed on Darwinism.

Shermer: But the designer could use natural selection and mutation.

Meyer: If so, then why did Darwin explicitly reject God having a role in these processes?

Shermer: I don’t believe in God because there isn’t enough evidence and it would require too many changes in my life. I like having autonomy from God and his moral demands. Also, we must always prefer material explanations, we can never infer that an intelligence played a role. I will only allow you to have two explanations of natural phenomena: 1) God didn’t do it, or 2) we don’t know.

Meyer: I like that you allow “we don’t know” as an explanation if we don’t know, because that is a rejection of dogmatic explanations that don’t fit the available evidence. But the arguments for design are based on what we do know, not what we don’t know – science gave us these arguments – and the progress of science has only strengthened them.

Conclusion

Well, I think it’s pretty clear who won, and who had the evidence! I like Michael Shermer, though, and I hope that he comes around to our point of view in time. At least he’s willing to debate, and he has a pretty moderate view compared to other Darwinian fundamentalists.

Other debates on Darwinism vs intelligent design

Michael Shermer debates Jonathan Wells at the pro-Darwinism Cato Institute (in 7 parts), MP3 audio is here.

Massimo Pigliucci debates Jonathan Wells for the pro-Darwinism PBS, downloadable video and audio.

John Lennox debates against Michael Shermer about the existence of God.

Further study

Here are posts on cosmological argument and the fine-tuning argument. I’ll respond to hopeful, but unwarranted, speculations about quantum mechanics and chaotic inflationary models, which I will be blogging about later. I’ll blog about molecular machines in a future post.

An essay on the origin of biological information by Meyer is here and a debate between two software engineers on it is here. I’ll also mention Meyer’s forthcoming book Signature in the Cell. Don’t forget about the upcoming debate between William Lane Craig and Francisco Ayala!

By the way, William Lane Craig has also debated Massimo Pigliucci on the topic “Does God Exist?”.

UPDATE: Did you see my post on why Darwinists don’t allow debates like this to happen in school classrooms?

Is there scientific evidence for an intelligent designer?

Dr. Walter L. Bradley
Dr. Walter L. Bradley

Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor, and a great example of the integration of Christian faith and a stellar academic career. He is not a “secret-service” Christian. Rejecting the notion of safe, private Christianity, he instead projects his Christian faith outward, where his students and colleagues can be aware of his beliefs.

Below I analyze a lecture I chose from the hundreds of public lectures he has given all over the world on the integration of Christian faith with other public, testable areas of knowledge. In this lecture, entitled “Is There Scientific Evidence for an Intelligent Designer?“, Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best current atheist response to this is to speculate that there may be an infinite number of unobservable and untestable universes. (I.e. – the Flying Spaghetti Monster did it)

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best atheistic response to this is to speculate that there is an unobservable and untestable hyper-universe outside our own. (I.e. – the Flying Spaghetti Monster did it)

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current atheistic response to this is to speculate that unobservable and untestable aliens seeded the earth with life. (I.e. – the Flying Spaghetti Monster did it)

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Conclusion

In all three areas, scientists expected that the data would be consistent with atheism. First, scientists expected that life could exist even if the physical constants and ratios were altered. The progress of science said NO. Second, scientists expected that the universe would be eternal. The progress of science said NO. Third, scientists expected that the origin of life would be simple. The progress of science said NO.
