Timothy G. Standish, biology First published in In Six Days Science and origins testimony #9

Edited by John F. Ashton

Dr. Standish is associate professor of biology at Andrews University in Berrien Springs, Michigan. He holds a B.S. in zoology from Andrews University, an M.S. in biology from Andrews University, and a Ph.D. in biology and public policy from George Mason University (University of Virginia), Charlottesville, Virginia. He teaches genetics at Andrews University and is currently researching the genetics of cricket (Achita domesticus) behavior.

--------------------------------------------------------------------------------

Reading The Blind Watchmaker by Richard Dawkins was a pivotal experience for me. I had recently started my Ph.D. program at George Mason University and eagerly signed up for a class entitled “Problems in Evolutionary Theory.” The Blind Watchmaker was required reading, and with growing enthusiasm I noted glowing endorsements printed on the cover. According to The Economist, this book was “as readable and vigorous a defense of Darwinism as has been published since 1859.” Lee Dembart, writing for the Los Angeles Times, was even more effusive: “Every page rings of truth. It is one of the best science books—of the best of any books—I have ever read.” A book that was “Winner of the Royal Society of Literature’s Heinemann Prize, and the Los Angeles Times Book Award” must contain nothing but undistilled brilliance. I felt smug with confidence as I paid for the book and left the store, brimming with ebullience to start reading.

After wading through all the hyperbole, I was stunned by the ideas put forward by Dawkins in The Blind Watchmaker. Rhetoric burnished the arguments with a glittering sheen, briefly giving the impression that pebbles were gems. But once each metaphor was stripped aside, the core ideas did not support the idea that natural selection could account for the origin of life and the meaningful complexity of organisms. Most startling to me was the realization that, one of the book’s core theses, in fact, violated the principle of natural selection.

Dawkins wove two ideas together in supporting Darwinism. The first idea was that, given enough chances, the improbable becomes probable. For example, flipping a coin ten times in a row and getting heads each time is very unlikely; one would only expect it to happen about 1 in 1,024 tries. Most of us would not sit around flipping coins just to see it happen, but if we had a million people flipping coins, we would see it happen many times. This phenomenon is publicized in the newspapers when lottery winners are announced. Winning a million-dollar jackpot is unlikely, but with millions of people purchasing tickets, eventually someone wins.

Dawkins admits that the odds on life starting from a random collection of chemicals is very slim, but given an immense universe and the billions of years it has existed, the improbable becomes probable. In this is echoed the logic of Ernst Haeckel, who wrote in his book The Riddle of the Universe, published in 1900:

Many of the stars, the light of which has taken thousands of years to reach us, are certainly suns like our own mother-sun, and are girt about with planets and moons, just as in our solar system. We are justified in supposing that thousands of these planets are in a similar stage of development to that of our earth … and that from its nitrogenous compounds, protoplasm has been evolved—that wonderful substance which alone, as far as our knowledge goes, is the possessor of organic life.

Haeckel was optimistic about the presence of conditions that could support life on planets other than earth, and it is in this that one of the problems with Dawkins’ argument emerges. While the universe is immense, those places where life as we know it could survive, let alone come into being, seem to be few and far between. So far, only one place has been discovered where conditions for life are present, and we are already living on it. Thus, there is not much cause for optimism that the universe is teeming with planets bathed in a primordial soup from which life might evolve. Dawkins wrote glibly of the immensity of the universe and its age, but failed to provide one example, other than the earth, where the unlikely event of spontaneous generation of life might occur. Even if the universe were teeming with proto-earths, and the spans of time suggested by modern science were available, this is still not a great argument, as if something is impossible—in other words, the odds of it happening are zero—then it will never happen, not even in an infinite amount of time. For example, even if we had our million people flipping coins, each with ten flips in a row, the odds on any one of them flipping and getting 11 heads in ten tries is zero because the odds of getting 11 heads in ten tries with one person is zero. The bottom line is that the odds on life evolving from nonliving precursors is essentially zero. Ironically, this was the stronger of the two ideas, or arguments, presented by Dawkins.

The second argument was presented as an analogy: imagine a monkey typing on a typewriter with 27 keys, all the letters in the English alphabet and the space bar. How long would it take for the monkey to type something that made any sense? Dawkins suggests the sentence spoken by William Shakespeare’s Hamlet who, in describing a cloud, pronounces, “Methinks it is like a weasel.” It is not a long sentence and contains very little meaning, but it works for argument’s sake. How many attempts at typing this sentence would it take a monkey, which would presumably be hitting keys randomly, to type the sentence?

As it turns out, the odds can be easily calculated as the probability of getting each letter or space correct raised to the power of the number of positions at which they have to be correct. In this case, the probability of the monkey typing “m” at the first position of the sentence is 1/27 (we won’t worry about capitalization). The sentence has 28 characters in it, so the probability is (1/27)28 or 1.2 x 10–40. That is about one chance in 12,000 million million million million million million! You would want a lot of monkeys typing very fast for a long time if you ever wanted to see this happen!

To overcome this problem with probability, Dawkins proposed that natural selection could help by fixing each letter in place once it was correct and thus lowering the odds massively. In other words, as a monkey types away, it is not unlikely that at least one of the characters it types will be in the correct position on the first try. If this letter was then kept and the monkey was only allowed to type in the remaining letters until it finally had the correct letter at each position, the odds fall to the point that the average diligent monkey could probably finish the task in an afternoon and still have time to gather bananas and peanuts from admiring observers. Dawkins got his computer to do it in between 40 and 70 tries.

Luckily I had taken biochemistry before reading The Blind Watchmaker. Organisms are made of cells, and those cells are composed of little protein machines that do the work of the cell. Proteins can be thought of as sentences like “Methinks it is like a weasel,” the difference being that proteins are made up of 20 different subunits called amino acids instead of the 27 different characters in our example. The evolution of a functional protein would presumably start out as a random series of amino acids one or two of which would be in the right position to do the function the protein is designed to do. According to Dawkins’ theory, those amino acids in the right location in the protein would be fixed by natural selection, while those that needed to be modified would continue to change until they were correct, and a functional protein was produced in relatively short order. Unfortunately, this ascribes an attribute to natural selection that even its most ardent proponents would question, the ability to select one nonfunctional protein from a pool of millions of other nonfunctional proteins.

Changing even one amino acid in a protein can alter its function dramatically. A famous example of this is the mutation that causes sickle cell anemia in humans. This disease causes a multitude of symptoms, ranging from liver failure to tower skull syndrome. It is caused by the replacement of an amino acid called glutamate, normally at position number six, with another amino acid called valine. This single change causes a massive difference in how the alpha globin subunit of hemoglobin works. The ultimate sad consequence of this seemingly insignificant mutation in the protein causes premature death in thousands of individuals each year. In other proteins, mutations to some, but not all, areas can result in a complete loss of function. This is particularly true if the protein is an enzyme, and the mutation is in its active site.

What Dawkins is suggesting is that a very large group of proteins, none of which is functional, can be acted on by natural selection to select out a few that, while they do not quite do the job yet, with some modification via mutation, can do the job in the future. This suggests that natural selection has some direction or goal in mind, a great heresy to those who believe evolutionary theory.

This idea of natural selection fixing amino acids as it constructs functional proteins is also unsupported by the data. Cells do not churn out large pools of random proteins on which natural selection can then act. If anything, precisely the opposite is true. Cells only produce the proteins they need to make at that time. Making other proteins, even unneeded functional ones, would be a wasteful thing for cells to do, and in many cases, could destroy the ability of the cell to function. Most cells only make about 10% of the proteins they are capable of producing. This is what makes liver cells different from those in the skin or brain. If all proteins were expressed all the time, all cells would be identical.

In reality, the problem of evolving life is much more complex than generation of a single functional protein. In fact, a single protein is just the tip of the iceberg. A living organism must have many functional proteins, all of which work together in a coordinated way. In the course of my research, I frequently physically disrupt cells by grinding them in liquid nitrogen. Sometimes I do this to obtain functional proteins, but more often to get the nucleic acids RNA or DNA. In any case, I have yet to find that the protein or nucleic acid I was working on was not functional after being removed from the cell, and yet, even though all the cell components were present and functional following disruption, I have never observed a single cell start to function again as a living organism, or even part of a living organism. For natural selection to occur, all proteins on which it is to act must be part of a living organism composed of a host of other functional protein machines. In other words, the entire system must exist prior to selection occurring, not just a single protein.

“Problems in Evolutionary Theory” was a class that made me realize the difficulties those who discount the possibility of a Creator have with their own theories. The problems with evolutionary theory were real, and there were no simple convincing resolutions.

Progressing in my studies, I slowly realized that evolution survives as a paradigm only as long as the evidence is picked and chosen and the great pool of data that is accumulating on life is ignored. As the depth and breadth of human knowledge increases, it washes over us a flood of evidence deep and wide, all pointing to the conclusion that life is the result of design. Only a small subset of evidence, chosen carefully, may be used to construct a story of life evolving from nonliving precursors. Science does not work on the basis of picking and choosing data to suit a treasured theory. I chose the path of science which also happens to be the path of faith in the Creator.

I believe God provides evidence of His creative power for all to experience personally in our lives. To know the Creator does not require an advanced degree in science or theology. Each one of us has the opportunity to experience His creative power in re-creating His character within us, step by step, day by day.

"Methinks it is like a weasel."

Who could possibly dream up a description more suited to the philosophy of evolution than millions of monkeys, one of which finally arrives at the truth.

What is missing from the equation is the meaning behind that sequence of letters. Monkeys typing randomly are doing just that, so even if they typed out a whole volume of Shakespeare, unless there were a design in place for interpereting the sequence of letters they are just random letters.

And showed that random guesses could arrive at a solution, just as evolution arrived at our "solution".

Since you're a fan, here's some more recent Gould (1994).

I like reading Gould because he shows some skepticism about the things in evolution that I find questionable (large transitional events).

Thanks for the quotes and links.

"The religious response to that seems to be that God created a "mature" universe that looks to us like it is billions of years old when in fact it is not"

My answer is God created a mature Adam. Adam was not created as a baby. Why would creating a mature Earth be somehow off limits for Him?

I see no reference in Genesis to Adam being an adult male at his creation.

ROFLMAO Most fossils have no carbon whatsoever. "Many people have been led to be skeptical of dating without knowing much about it. For example, most people don't realize that carbon dating is only rarely used on rocks."

http://www.asa3.org/ASA/resources/Wiens.html

I don't see how "excess" carbon is pertinent to dating fossils that are millions of years old, when it is the rock around the fossil that is dated, not the fossil itself.

"With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr. Hovind is confusing the carbon-14 "clock" with other radiometric "clocks.""

"The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period. Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. It's just one of the tricks that have been used to make the work a little more precise." The above is from a different article, but it seems to address the claims you are making.

"If you get your information from a creationist source, you'd better triple-check it! Errors get handed down in the creationist literature like the family jewels!"

Another article contained the above warning. I think you should heed it.

Gould just said he resents people doing what you just did, but you went ahead and put words in his mouth anyway.

What large transitional events are you talking about? Most scientists think evolution takes place rather gradually.

"I'm taking the history recorded in Genesis as one piece of evidence and I'm trying to find theories that can fit with all the evidence."

See, you are doing it wrong. First you must have hypotheses that are supported by evidence. Then when you get a bunch of hypotheses together that have actual evidence, you can form a theory explaining an observed phenomenon with them. They all have to explain the theory. You can't have any hanging out, like there was no global flood.

Actually it is evidence and it is supported by scientific analysis. It is all supported hypothesis and it all fits the theory, making it unlike any "creation science" extant.

Dr. Wiens:

"Rightly Handling the Word of Truth

As Christians it is of great importance that we understand God's word correctly. Yet from the middle ages up until the 1700s people insisted that the Bible taught that the Earth, not the Sun, was the center of the solar system. It wasn't that people just thought it had to be that way; they actually quoted scriptures: "The Earth is firmly fixed; it shall not be moved" (Psalm 104:5), or "the sun stood still" (Joshua 10:13; why should it say the sun stood still if it is the Earth's rotation that causes day and night?), and many other passages. I am afraid the debate over the age of the Earth has many similarities. But I am optimistic. Today there are many Christians who accept the reliability of geologic dating, but do not compromise the spiritual and historical inerrancy of God's word."

"Prove to me that Argon isn't seeping into the rocks and fossils and contaminating everything that has been dated."

If we "prove" this to you, will you accept that evolution is the fact it is?

He didn't particularly care for my response that it would be MORE likely for the AR to leak out than leak into the rocks.

Apparently, God did not know before hand that a pet would not suffice for Adam. And Adam gaveth names to all cattle, and to the fowl of the air, and to every beast of the field; but for Adam there was not found an help meet for him.  (Ge 2:20) I guess since the speed of light had not slowed down yet, the kryptonite was interfering with omniscience.

I can prove that it isn't (neither as a contamination in "everything", nor as a contamination in any particular sample) because if it were, that would be obvious as a nonlinearity on the isochron lines.

Most dating has not been done by using the Isochron Parent/Daughter/Daughter method, so on the vast majority of dates, we don't know whether the P/D/D line was linear.

What's more, ICR has several research papers out showing, non-linear isochrons for Potassium Argon and if I read the first article below they have an example of a linear Argon Isochron showing a discordant date with a linear Isochron of another Isotope.

DISCORDANT POTASSIUM-ARGON MODEL AND ISOCHRON "AGES" FOR CARDENAS BASALT (MIDDLE PROTEROZOIC) AND ASSOCIATED DIABASE OF EASTERN GRAND CANYON, ARIZONA

From the conclusion..."Both the old and new data imply that the rocks leaked argon in nearly exact proportion to the abundance of potassium producing a "leakage isochron", an explanation not supported by a quantity of an appropriate mineral or mesostasis phase. "...."All three explanations offered as alternatives to the argon loss models invalidate using the K-Ar system as conventional geochronology would assume."

ANDESITE FLOWS AT MT NGAURUHOE, NEW ZEALAND, AND THE IMPLICATIONS FOR POTASSIUM-ARGON "DATING"

"Therefore, these considerations call into question all K-Ar "dating", whether "model ages" or "isochron ages", and all 40Ar/39Ar "dating", as well as "fossil dating" that has been calibrated against K-Ar "dates".

And while a linear P/D/D line is a logical test for contamination from Argon, even if not completely reliable, it dones nothing for excess argon captured in rock formation.

Well, his example was radon leaking out, so I don't see any problem with him buying argon leaking out.

You are doing an excellent job of holding his feet to the fire, btw.
