Michael Ruse debates Stephen C. Meyer on intelligent design and evolution on NPR

Here’s a debate between:

  • Stephen C. Meyer, author of Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design
  • Michael Ruse, Director of the History and Philosophy of Science Program at Florida State University

The MP3 file is here. (28 minutes)

The following summary is rated S for Slightly Snarky. Reader discretion is advised.

Topics:

  • Moderator: (to Meyer) define creationism, evolution, and intelligent design
  • Meyer: creationism is based on an interpretation of the Bible
  • Meyer: evolution is an unguided process of mutation and selection that produces organisms
  • Meyer: intelligent design is the idea that the best explanation for certain features of life
  • Moderator: (to Ruse) Where do you disagree?
  • Ruse: Intelligent design is similar to creationism, but I won’t say how exactly
  • Meyer: ID is a good explanation for the sudden origin of animal body plans in the Cambrian era
  • Moderator: (to Meyer) Is the designer God? Is the designer the Christian God?
  • Meyer: No, ID theory is an inference that is rooted in scientific evidence, not in a religious text
  • Meyer: ID can be inferred from the origin of biological information and from molecular machines
  • Moderator: (to Ruse) Where do you disagree?
  • Ruse: Meyer is disingenuous because ID requires the designer to be God
  • Meyer: The biological evidence for intelligent design by itself does not implicate God
  • Meyer: The fine-tuning of the cosmos is intelligent design in physics, and that *would* require God
  • Moderator: (to Meyer) Explain what the Cambrian explosion is
  • Meyer: sudden origin of 36 body plans in 10 million years 530 million years ago
  • Moderator: So you think that 36 body plans in 10 million years is too sudden for Darwinian mechanisms to produce?
  • Meyer: Yes, for two reasons. One, there are no precursors prior to the start of the explosion in complexity
  • Meyer: And two, the complexity of animal life includes code, circuitry, hierarchies – best explained by a designer
  • Moderator: (to Ruse) Is it a problem for you?
  • Ruse: There is no peer-reviewed paper that denies that the Ediacaran fauna are precursors to the Cambrian animals
  • Ruse: There is no peer-reviewed paper that denies that microfossils are precursors to the Cambrian animals
  • Ruse: There is no peer-reviewed paper that denies that animal complexity goes from simple to complex in the fossil record
  • Ruse: There is no peer-reviewed paper that shows that the Cambrian explosion took place over a few million years
  • Ruse: There is no peer-reviewed paper that shows that there were complex organ types at the start of the Cambrian explosion
  • Ruse: There is no peer-reviewed paper that denies that we already have a materialist explanation for the Cambrian explosion
  • Ruse: everything is solved! nothing to see here! (folds arms and beams) I trust that my unsupported assertions have relieved your doubts, yes?
  • Moderator: Is intelligent design undermined by more recent science?
  • Meyer: no, there is an absence of precursor fossils in the period before the Cambrian explosion
  • Meyer: there are other things that make the problem even worse for naturalism, like information from epigenetics
  • Moderator: (to Ruse) Answer that
  • Ruse: He is just pulling out passages out of context because he is a creationist!
  • Moderator: The leftist New Yorker reviewer Gareth Cook says that the Cambrian explosion took tens of millions of years
  • Meyer: Actually, the peer-reviewed science is clear that the standard date is at most 10 million nears
  • Moderator: (to Ruse) Deny the mainstream date
  • Ruse: Well, Prothero says no! Ho ho ho! (folds arms) He just says it. No it’s not published in peer-reviewed research
  • Ruse: We know so much more than Darwin did, how could the progress of science disprove my materialist pre-supposition? It’s unpossible!
  • Moderator: (to Meyer) Isn’t ID pseudo-science?
  • Meyer: If we limit ourselves to materialist explanations only, then we cannot infer intelligence when we see artifacts like the Rosetta Stone
  • Meyer: wind and erosion is not an adequate explanation for certain systems – systems that are rich in information
  • Meyer: the best explanation is the explanation that relies on known causes – we know that intelligence produces information
  • Moderator: (to Meyer) so the intelligence is the best explanation of systems that have information?
  • Meyer: yes, think about software code – the best explanation of new computer instructions is an intelligence
  • Meyer: we have uniform and repeated experience of intelligence bringing new information into being, and new animals need new information
  • Moderator: (to Ruse) must science only work with natural explanations?
  • Ruse: intelligent design is religion! Ho ho ho ho! (folds arms)
  • Ruse: there is no a priori way of ruling out supernatural causes in order to explain nature
  • Ruse: We don’t need to introduce supernatural causes to explain information in living systems or in software code
  • Ruse: Steve is asking me to explain the Cambrian explosion, but why does he want me to explain that?
  • Ruse: How did anything start to fly? How did whales come? There, those questions explain the Cambrian explosion naturalistically
  • Ruse: Steve’s answer to explain new information is to bring in miracles, like when he said that new computer code requires God
  • Ruse: inferring intelligence as an explanation for information like the computer code is religion! God! Creationism! Prayer in schools!
  • Ruse: we have to keep looking for naturalistic explanations for the Big Bang, the DNA, the fine-tuning, the Cambrian fossils, etc.
  • Ruse: we are never justified in inferring an intelligence to explain information, because that would deny my religion of materialism
  • Moderator: (to Ruse) what are the requirements for a theory to be scientific?
  • Ruse: any explanation has to be naturalistic, because I am an atheist and that’s my religion, and we can’t go against my religion
  • Ruse: it’s “really stupid” to infer God as the explanation of the creation of the entire physical universe or the cosmic fine-tuning
  • Moderator: (to Meyer) why is intelligent design so popular when we have court cases saying it is not science?
  • Meyer: the Discovery Institute does not have an agenda to teach intelligent design in public schools
  • Meyer: intelligent design is about inferring intelligence as a causal explanation for information in living systems, and elsewhere
  • Moderator: (to Ruse) are evolutionists unwilling to entertain the possibility of intelligence being the best explanation?
  • Ruse: scientists have to make sure that that all their explanations don’t go outside of the materialist reservation
  • Ruse: intelligent design is evangelical Christianity dressed up to look like science, the Dover judge said so
  • Ruse: Meyer is disingenuous! Ho ho ho ho ho! (folds arms contentedly)
  • Meyer: first, judges don’t decide science, evidence decides science
  • Meyer: the Dover people made a mistake by trying to go to the courts to get things into the schools
  • Meyer: intelligent design is about research, writing books and papers based on what we learn from science
  • Moderator: (to Ruse) is intelligent design dangerous?
  • Ruse: yes, intelligent design is about politics, it’s not about cosmic fine-tuning, origin of life, molecular machines or Cambrian explosion
  • Ruse: intelligent design is about abstinence, prayer in schools, burdening women with unwanted babies and male-female marriage
  • Ruse: my reason for opposing ID is the socially conservative agenda which emerges from protein folding probability calculations
  • Ruse: I don’t want to be drafted to fight in Vietnam, I don’t want them to take away my drugs, etc. so that’s why I believe Darwinism
  • Moderator: (to Meyer) why do you want to take abortion away, you meany?
  • Meyer: actually, intelligent design is about science, and in any case National Review gave my book a bad review
  • Moderator: (to Ruse) are science and religion in conflict?
  • Ruse: well religion can just abstain from making any claims about the physical world, and just stick to subjective nonsense – that’s fair
  • Moderator: (to Meyer) isn’t all opposition to evolution rooted in fundamentalist religion?
  • Meyer: you can believe in Darwinism and be a theist, but the real reason for doubting Darwinism is the scientific evidence, not religion

Tell me how you think Dr. Meyer did in the comments.

How brief was the period in which the Cambrian phyla suddenly appeared?

The Cambrian explosion refers to the sudden appearance of new body plans in the fossil record. ID proponents think that the period is between 5-10 million years at the most. Naturalists want to stretch out the period in which the body plans appear to tens of millions of years. The two sides can’t both be right. What’s the truth?

Evolution News has the answer.

Excerpt:

To establish the length of the most explosive period of innovation within the Cambrian explosion itself, Meyer cites the work of MIT geochronologist Samuel Bowring and his colleagues as well the work of another group led by Smithsonian paleontologist Douglas Erwin. The Bowring-led study showed that (in their words) “the main period of exponential diversification” within the Cambrian lasted “only 5-6 million years” (emphasis added). Meyer explains:

An analysis by MIT geochronologist Samuel Bowring has shown that the main pulse of Cambrian morphological innovation occurred in a sedimentary sequence spanning no more than 6 million years. Yet during this time representatives of at least sixteen completely novel phyla and about thirty classes first appeared in the rock record. In a more recent paper using a slightly different dating scheme, Douglas Erwin and colleagues similarly show that thirteen new phyla appear in a roughly 6-million-year window. (p. 73)

[…][T]ake a look first at the following figure that Bowring and his colleagues included in their definitive 1993 article, published in the journal Science. They use radiometric methods to date the different stages of the Cambrian period, including the crucial Tommotian and Atdabanian stages in which the greatest number of new animal phyla and classes arise. Note that the so-called Manykaian stage of the Cambrian period lasts about 10-14 million years. Note also that the main pulse of morphological innovation didn’t begin during this stage but rather during the Tommotian and Atdabanian — a period that they describe as taking between “5 to 10 million years,” and in a more detailed passage as taking about 5-6 million years.

[…]In the figure above, the Tommotian and Atdabanian stages of the Cambrian period together span only about 5 million years, starting at about 530 and ending about 525 million years ago. Bowring’s figure also depicts the total number of classes and orders present at any given time during the Cambrian period. The biggest increases in morphological innovation occur during the Tommotian and Atdabanian stages. Indeed, during this period the number of known orders nearly quadruples. Moreover, Bowring and his colleagues also make clear that this period corresponds to the main pulse of Cambrian morphological innovation as measured by the number of new phyla and classes that first appear. They note that, while a few groups of animals do arise in the earliest Manykaian stage of the Cambrian, the most rapid period of “exponential increase of diversification,” corresponding to the Tommotian and Atdabanian stages, “lasted only 5 to 6 m.y.”

You can see the figure they are reference in the Evolution News article.

Also, check out these clips that explain the Cambrian explosion:

Part 1:

Part 2:

The first clip features James Valentine, a professor of biology at the University of California who just co-authored a new book on the Cambrian explosion and is not a proponent of intelligent design.

The consensus among scientists regarding the period of time in which the new body plans appear is 5-6 million years. Biologically speaking, that’s a blink of an eye. You aren’t going that kind of complexity and innovation in such a short period of time any more than you can expect to win the lottery by buying 5-6 million tickets when the odds of winning are 1 in a googol (10 to the 100th power – 1, followed by 100 zeroes). You don’t have enough lottery tickets to make winning the lottery likely. Similarly, 5-6 million years is not enough time for naturalistic mechanisms to code brand new body plans from scratch. It would be like trying to research and write a Ph.D thesis during a single lunch hour. It’s just not enough time to produce the amount of information that’s required.

Did your science textbook teach that embryo drawings prove evolution?

Haeckel's embryos and scientific fraud
Haeckel’s embryos and scientific fraud

Jonathan Wells, a biologist with Ph.Ds from Yale and UC Berkeley, writes about one example of fake evidence here:

Charles Darwin thought that “by far the strongest” evidence that humans and fish are descended from a common ancestor was the striking similarity of their early embryos. According to Darwin, the fact that “the embryos of the most distinct species belonging to the same class are closely similar, but become, when fully developed, widely dissimilar… reveals community of descent.” 2 To illustrate this, German Darwinist Ernst Haeckel made some drawings in the 1860s to show that the embryos of vertebrates (fish, amphibians, reptiles, birds and mammals) look almost identical in their earliest stages.

But Haeckel faked his drawings. Not only do they distort vertebrate embryos by making them appear more similar than they really are (in a way that Stephen Jay Gould wrote “can only be called fraudulent” 3), but they also omit classes and stages that do not fit Darwin’s theory. Most significantly, Haeckel omitted the earliest stages, in which vertebrate embryos are strikingly different from each other. The stage he portrayed as the first is actually midway through development. Yet according to Darwin’s logic, early dis-similarities do not provide evidence for common ancestry.

Haeckel used his faked drawings to support not only Darwinian evolution, but also his own “Biogenetic Law,” which stated that embryos pass through the adult stages of their ancestors in the process of development.

…Haeckel’s drawings were exposed as fakes by his own contemporaries, and his Biogenetic Law was thoroughly discredited by 20th century biologists. It is now generally acknowledged that early embryos never resemble the adults of their supposed ancestors. A modern version of recapitulation claims that early embryos resemble the embryos of their ancestors, but since fossil embryos are extremely rare, this claim is little more than speculation based on the assumption that Darwin’s theory is true.

Now the standard response from Darwinists: no textbooks are still using the fraudulent embryo images.

You can see the actual faked pictures from the modern textbooks here. These textbooks were being produced as late as 2004, even though the fraud was detected in the 1800s! Is this the vaunted self-correction of science, or science being twisted to support social and political goals?

And this excerpt from that article is interesting:

Some Darwinists continue to deny that there has been any misuse of Haeckel in recent times. If that is the case, why did Stephen Jay Gould attack how textbooks use Haeckel in 2000? Gould wrote: “We should… not be surprised that Haeckel’s drawings entered nineteenth-century textbooks. But we do, I think, have the right to be both astonished and ashamed by the century of mindless recycling that has led to the persistence of these drawings in a large number, if not a majority, of modern textbooks!” (emphasis added) Similarly, in 1997, the leading embryologist Michael K. Richardson lamented in the journal Anatomy and Embyology that “Another point to emerge from this study is the considerable inaccuracy of Haeckel’s famous figures. These drawings are still widely reproduced in textbooks and review articles, and continue to exert a significant influence on the development of ideas in this field.” (emphases added)

Here is a link to the peer-reviewed journal Science, where there is an article talking about the fraudulent embryo drawings. Yes – the drawings really are fraudulent.

And finally, Casey Luskin has a new post up at Evolution News that lists all the textbooks that contain the fraudulent drawings. One is dated 2013! The drawings just keep getting recycled over and over as a “proof” of evolution.

What should you say when a co-worker asks you if you believe in evolution?

How did life begin?
How did life begin?

You only have a few minutes to respond, and your answer is going to go all around the office. So what should you say?

Stephen C. Meyer has the answer at Evolution News.

He writes:

I spoke recently to the Faith and Law group on Capitol Hill in D.C., a regular meeting of congressional staffers. At their request, I addressed the topic: “What Should Politicians Say When Asked About Evolution?”

[…]In my talk, I not only gave an answer to the question “What Should Politicians Say When Asked About Evolution?” but I first explained why it is a difficult question for many politicians, especially conservative ones, to answer. There are three main reasons.

I’m only going to give the first reason:

First, the term “evolution” can mean several different things, ranging from (1) the scientifically uncontroversial idea of “change over time” (think of small-scale variations in the shape and size of Galapagos finch beaks) to (2) the more controversial notion of universal common ancestry (think of Darwin’s tree of life) to (3) the increasingly controversial idea that the mechanism of natural selection and random mutation have produced all the forms of life we see today without any guidance or design. The last meaning of “evolution” is what Richard Dawkins calls the “Blind Watchmaker” thesis.

Equivocation in the definition of evolution can make it difficult for a politician to express legitimate skepticism about the controversial meanings of evolution without being presented to the public as being ignorant of established fact, or “anti-science.” In Walker’s recent case, media coverage traded on precisely this ambiguity to present him as being at odds with the majority of the American public, not to mention the scientific establishment. Media outlets repeatedly cited a poll showing that 65 percent of the American people believe that “human beings have changed over time” — i.e., the first and non-controversial meaning of evolution — without mentioning that a huge majority of Americans (and many scientists) reject the third and distinctly controversial meaning of evolution — the idea that the cause of the change over time is an unguided and undirected mechanism.

You can click through and read the other two, but for now, let’s jump to the right way to answer the question:

Most politicians, of course, don’t know about this tumult in the field or of any of the scientific problems with modern Darwinism. They are thus often unnecessarily intimidated by the consensus that supposedly exists in its favor.

In light of all this, any candidate asked about “the theory of evolution” would be well advised to give an answer that affirms the need to teach about contemporary evolutionary theory, but one that also makes clear distinctions between the different meanings of evolution and indicates an awareness of the scientific problems with the standard theory as demonstrated in the scientific literature. And frankly this is not party-specific advice. The scientific literature says what it says, whether consulted by Democrats or Republicans.

Politicians can also say that they think students should learn about those problems since they regard knowledge of the actual status of the theory as a matter of basic scientific literacy. They should not frame the issue as one of “Science versus the Bible,” or answer as if they were being asked about their personal religious beliefs, or as if they think the only alternative to current dogmatic teaching of Darwinian evolution (with its strict insistence on undirected evolution) is to teach Bible-based creationism. They can challenge the dogmatic (and often ideological) way the topic is currently taught and at the same time affirm their commitment to scientific literacy, academic freedom, and critical thinking.

And here’s a sample question and answer:

Reporter: “Do you believe in evolution?”

Candidate: “Of course, I believe that organisms have changed over time. I certainly believe in evolution in that sense. But I am skeptical about unguided evolution — the idea that natural selection and random mutations have produced the major changes in the history of life we observe without any guidance or design. In fact, in peer-reviewed scientific publications, many scientists have expressed doubts about the creative power of natural selection and random mutation. I think that students in learning about the modern version of Darwin’s theory should learn why scientists have these doubts. Understanding the strengths and weaknesses of scientific theories is a matter of basic scientific literacy. And there are scientific weaknesses in modern Darwinian theory.”

This is the right answer because you pull in the majority of people – the young Earth creationists, the intelligent designists and the guided evolutionists. The only people you leave out are the flat-out materialist naturalists, and they are in the minority. So that’s how you answer the question. It would probably help a great deal if you had read both of Meyer’s books on biological evolution, since he writes at the highest level – far higher than left-wing journalists who probably dropped biology because it was too much work.

He is President elect of the ASA and will serve his term in 2008.

You can read more about his recent research in this article from Science Daily.

Below, I analyze a 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.

The MP3 file is here.

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 NOT 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 non-theistic response to this argument is to postulate a multiverse, but that is very speculative and there is no experimental evidence that supports 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 non-theistic response to this argument is to postulate a hyper-universe outside of ours, but that is very speculative and there is no experimental evidence that supports 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 non-theistic response to this is to speculate that aliens may have seeded the Earth with life at some point in the past.

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.
