Evolution News reported on a 27-minute debate featuring Dr. Stephen C. Meyer – probably the best proponent of intelligent design there is.

Description:

We often say that Darwinists are reluctant to debate advocates of intelligent design, but here are two who deserve a tip of the hat. Keith Pannell is a chemist at the University of Texas at El Paso who hosts a program, Science Studio, on the NPR station there. He invited Stephen Meyer on to talk about the science of ID, pegged to the Dover anniversary.

Clearly Pannell is an ID critic so he gets kudos for being willing to have a civil and informative conversation. Perhaps feeling insecure about facing the author of Darwin’s Doubt by himself, Dr. Pannell invited a biologist colleague, Ricardo Bernal, to serve as “co-host.”

So it was two against one, but no worries. Meyer is, as always, superb, and the discussion sounds like it was an education for the two Texas scientists. Listen and enjoy.

I took a back-up of the MP3 file here.

Summary:

  • How did Dr. Meyer get interested in science?
  • What is intelligent design? (origin of life, fine-tuning)
  • What is creationism? (young Earth, different epistemology)
  • Who does Dr. Meyer think the intelligent designer is?
  • Finding the best explanation from multiple competing hypotheses
  • Critic: aren’t you arguing for a designer from ignorance, then?
  • The importance of naturalists acknowledging what they do and do not know about the origin of life
  • We do have experience with intelligent causation, whenever we sequence symbols to have meaning and purpose, e.g. – writing
  • Critic: information in DNA is not digital information, is it?
  • Information in the cell follows a 4-character alphabet
  • the sequences are composed of many parts / symbols
  • the sequences themselves are specified to have function
  • Critic: the complexity just emerges from change over time
  • the origin of the first life is immune to explanation of change over time, because there is no replication – this is the first replicator
  • Critic: but isn’t it just ignorance about the origin of life?
  • what we do is look at a number of competing hypothesis and what they are capable of, and see whether each cause is capable of generating the effects we observe in nature
  • Critic: where is the experimental verification of your theory?
  • well, in the appendices of Signature of the Cell, we predicted that the non-coding regions of DNA (junk DNA) would be found to have function, and that was later proven out
  • the Darwinists said that non-coding regions of the DNA was junk, but that’s not what has been proven experimentally
  • Critic: where was this prediction written up, who wrote it?
  • intelligent design theorists predicted it: Dembski, Kenyon, Mims, Sternberg
  • Critic: but we used the scientific method to disprove the Darwinian predictions, you don’t like the scientific method
  • intelligent design proponents love science, and the scientific method, and they do work in labs to confirm their hypotheses, (WK:for example, the probability of generating a protein by chance)
  • Critic: what about the Dover court case that you lost?
  • the Discovery Institute objected to actions taken by the Dover school board
  • Critic: what about the molecular machines, how are they related to intelligent design?
  • even in the simplest living organisms, there are tiny machines that are tightly integrated, and cannot be built up in a stepwise fashion
  • Critic: I’ve worked with the ATP-synthase and other molecular machines, but “you can kind of begin to tease how some of these molecular machines have come about” – pieces have multiple functions, and they are co-opted into larger systems
  • the problem with the co-option argument breaks down when you look at the specific details of different machines
  • for example – the type III secretory system cannot be an precursor to the bacterial flagellum, it is younger, not older than the bacterial flagellum
  • Critic: what would it take for your view to be falsified?
  • demonstrable undirected processes that are capable of creating functional information in DNA, or processes that can build up an irreducibly complex molecular machine within the time available with a decent probability

Information Enigma: 21-minute video explains intelligent design

Can random mutation and natural selection create new functional information?
Can random mutation and natural selection create new functional information?

The video is here:

I have read and listened and watched a lot of material on intelligent design, but I have never seen so much value packed into such a short lecture. I really hope you’ll watch this and that it’s helpful to you.

Summary:

  • the big question when discussing the origin of life: where did the information in living systems come from?
  • Until 530 million years ago, the oceans were largely devoid of life
  • In a 10 million year period, many new forms of animal life emerged
  • New biological forms of life require new information
  • the discovery of DNA shows that living systems work because cells have information that allows them to build the components of molecular machines: cell types, proteins, etc.
  • can random mutation and natural selection create new functional information?
  • normally, random mutations tend to degrade the functionality of information, e.g. – randomly changing symbols in an applications code does not usually introduce useful new functions, it usually renders what is there non-functional
  • the majority of possible sequences will NOT have functions, so random mutations will more likely give you non-functional code, rather than functional code
  • example: a bicycle lock  with 4 numbers has many possible sequences for the 4 numbers, and only one of them has unlock functionality, the rest have no functionality
  • if you have lots of time, then you might be able to guess the combination, but if the lock as has 10 billion numbers, and only one combination that unlocks, you can spend your whole life trying to unlock it and won’t succeed
  • how likely is it to arrive at a functional protein or gene by chance? Is it more like the 4-dial lock (can be done with lots of time) or the 10 billion dial lock (amount of time required exceeds the time available)?
  • the probability is LOW because there is only one sequence of numbers that has unlock function
  • consider a short protein of 150 amino acids has 10 to the 195th power possible sequences
  • if many of these sequences of amino acides had biological function, then it might be easier to get to one by random mutation and selection than it is with a lock that only unlocks for ONE sequence
  • how many of the possible sequences have biological function?
  • Thanks to research done by Douglas Axe, we now know that the number of functional amino acid sequences for even a short protein is incredibly small…
  • Axe found that the odds of getting a functional sequence of amino acids that will fold and have biological function is 1 in 10 to the 77th power
  • Is that number too improbable to reach by chance? well, there are 10 to 65th atoms in the entire Milky Way galaxy… so yes, this is a very improbable outcome
  • can random genetic mutations search through all the sequences in order to find the one in 10 to the 77th power one that has biological function? It depends on how much guessers we have and how many guesses we get in the time available
  • even with the entire 3.5 billion year history of life on Earth, only about 10 to the 40th organisms have ever lived, which far smaller fraction of the 10 to the 77th total sequences
  • even with a very fast mutation rate, you would not be able to reach a functional protein even with all that time, and even with all those organisms

I was once having a discussion with a woman about the research that Axe did at the Cambridge University lab. He published four articles in the Journal of Molecular Biology. I held out one of the papers to her and showed her the numbers. She said over and over “I hate the Discovery Institute! I hate the Discovery Institute!” Well, yeah, but you can’t make the Journal of Molecular Biology go away with hating the Discovery Institute. JMB is peer-reviewed, and this was experimental evidence – not a theory, not a hypothesis.

We have been blessed by the Creator and Designer of the universe in this time and place with overwhelming evidence – an abundance of riches. For those who have an open mind, this is what you’ve been waiting for to make your decision. For the naturalists who struggle so mightily to block out the progress of experimental science, they’ll need to shout louder and shut their eyes tighter and push harder to block their ears. Maybe if they keep screaming “Star Trek” and “Star Wars” over and over to themselves, they will be able to ignore the real science a little longer.

Harvard University astrophysicist discusses fine-tuning in the Washington Post

Christianity and the progress of science

I’m pretty sure my readers already know about the fine-tuning argument, but it’s not every day you see it discussed (however briefly) in a far-left mainstream newspaper like the Washington Post. (H/T Carmen)

The author is Howard A. Smith:

Howard A. Smith is a senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, and a member of the Harvard Department of Astronomy. His research emphasizes the origins of stars, stellar systems and galaxies, and he is an author on more than 250 scientific articles. Previously he was Chair of Astronomy at the Smithsonian’s National Air and Space Museum; he also served for three years as a visiting scientist at NASA Headquarters.

Here is some of what he wrote in the far-left Washington Post:

There was a time, back when astronomy put Earth at the center of the universe, that we thought we were special. But after Copernicus kicked Earth off its pedestal, we decided we were cosmically inconsequential, partly because the universe is vast and about the same everywhere. Astronomer Carl Sagan put it this way: “We find that we live on an insignificant planet of a humdrum star.” Stephen Hawking was even blunter: “The human race is just a chemical scum on a moderate-sized planet.”

An objective look, however, at just two of the most dramatic discoveries of astronomy — big bang cosmology and planets around other stars (exoplanets) — suggests the opposite. We seem to be cosmically special, perhaps even unique — at least as far as we are likely to know for eons.

The first result — the anthropic principle — has been accepted by physicists for 43 years. The universe, far from being a collection of random accidents, appears to be stupendously perfect and fine-tuned for life. The strengths of the four forces that operate in the universe — gravity, electromagnetism, and the strong and weak nuclear interactions (the latter two dominate only at the level of atoms) — for example, have values critically suited for life, and were they even a few percent different, we would not be here. The most extreme example is the big bang creation: Even an infinitesimal change to its explosive expansion value would preclude life. The frequent response from physicists offers a speculative solution: an infinite number of universes — we are just living in the one with the right value. But modern philosophers such as Thomas Nagel and pioneering quantum physicists such as John Wheeler have argued instead that intelligent beings must somehow be the directed goal of such a curiously fine-tuned cosmos.

It seems likely that exoplanets could host extraterrestrial intelligence. But intelligence is not so easy to produce. Paleontologist Peter Ward and astronomer Donald Brownlee summarize the many constraints in their book “Rare Earth: Why Complex Life is Uncommon in the Universe ” and show why it takes vastly more than liquid water and a pleasant environment to give birth even to simple (much less complex) life. At a minimum, it takes an environment stable for billions of years of evolution, plus all the right ingredients. Biologists from Jacques Monod to Stephen Jay Gould have emphasized the extraordinary circumstances that led to intelligence on Earth, while geneticists have found that DNA probably resulted from many accidents. So although the same processes operate everywhere, some sequences could be unlikely, even astronomically unlikely. The evolution of intelligence could certainly be such a sequence.

There is, moreover, a well-known constraint: the finite speed of light, which ensures that even over thousands of years we will only be able to communicate with the comparatively few stars (tens of millions) in our cosmic neighborhood. If the combined astronomical, biological and evolutionary chances for life to form and evolve to intelligence are only 1 in 10 million, then we probably have no one to talk to.

What is really strange is when I try to talk to atheists about this evidence, and they tell me about Star Trek and Star Wars and how the universe isn’t specially designed and there are aliens everywhere.  Atheists like the science fiction, they don’t like the science facts.

If you would like to hear a good lecture on the fine-tuning argument, this one with Robin Collins is very good. You can hear him debate the fine-tuning argument with Peter Millican here. And in this lecture Collins talks about his new research. Another discussion between Luke Barnes and an atheist is useful to understand how objections to the argument can be answered.
