Being a big fan of the theory of
evolution, it disappoints me to no end to see that there is one entity
where there are no apparent signs of evolution and that entity is the
creationists’ arguments against the theory of evolution. I have been
sparring with creationists for more than a decade now in a sincere
effort to understand their viewpoint and present mine. I’m a novice when
it comes to the theory of evolution. People with monumental knowledge
and skills have been answering these creationist arguments for ages it
seems but the arguments are still there refusing to grow and improve.
That is why I found Mr. Ziauddin Ahmad’s essay
“Nature on Nature” so refreshing. It didn’t resort to the
same old rehashing of old and tired arguments. Once
again, I am up against rehashed arguments of creationism in shape of
this article by
Harun Yahya.
The argument is very simple and
it’s based on personal incredulity. In simplest words possible, it is,
“how can something happen that I can not fathom?” How can natural
selection, an unguided and blind force can give rise to such complex
mechanisms? Unbelievable, hence false. And yet these very same people
find no trouble in believing that there is a deity that said “Be” and
everything “Became”. That they find no trouble comprehending but
simple mathematics is unbelievable. I say simple mathematics because
that’s almost all there is to complexity in nature. Maybe because most
of us don’t think in exponential terms so the idea of accumulative
exponential growth seems strange to grasp.
When I was teaching computer
sciences (and corrupting young minds in the process), I used to give
certain assignments to my students who were learning to write computer
programs. I designed these assignments to challenge their programming
expertise as well as their mental notions. One of my
favorite assignments in the early part of their training used to be the
following.
A normal page of paper is 0.1 mm
thick. That’s one-tenth part of a one thousandth of a meter (or 0.0001
meter). The distance of moon from earth is 384,400 KM (or 384.4 million
meters). Every time you fold a paper, its thickness gets doubled. Lets
suppose that we have a page that is unimaginably wide and long, how many
times would I need to fold it so that it touches moon?
Before they started working on
the assignment, I used to ask them to venture guesses. Their guesses
usually ranged somewhere between 10,000 and 384 million times (except
for some occasional brainiac who’d ruin my fun with guessing a number
close to the actual answer). And then I used to see their faces with
amusement when they wrote the programs and found out that the answer is
42. Just 42. In fact 42 folds would take the paper 50,000 KM beyond the
moon. Most of them would look at the result with disbelief and checked
if they made an error in their programs. Why? Because they had never
thought about the power of accumulative exponential growth.
The argument from personal
incredulity that I described very much forms the basis of the main
creationist thought and that is quite visible in Mr. Yahya’s essay. Lets
deal with the essay now.
The article purportedly deals
deathblows to the theory of evolution and the philosophy of materialism.
I don’t care much about the philosophy of materialism, or any philosophy
for that matter, so I wouldn’t spend much time on that part.
The author starts by presenting
the example of DNA by comparing it to a book full of information. I
would rather compare DNA with a recipe book instead of informational
book. One might consider that a difference of semantics which it is not.
For current discussion, lets not get into that. Here is what Mr. Yahya writes,
It is information which separates a volume of the
Encyclopedia Britannica from a "book" formed by randomly arranged
letters like ABICLDIXXGGSDLL. Both have paper, ink and binding, but one
has information while the other does not. The source of information is
the author of that book, a mind with consciousness. Therefore we can't
deny that an intelligent being placed the information in DNA there.
That's quick. Just
because DNA is useful information and not junk like ABICLDIXXGGSDLL,
there’s got to be a writer and that’s that. One must give credit where
it’s due. I have seen the argument of intelligent design presented
hundreds of times but this is the shortest form of it ever.
Anyway, the analogy with the Encyclopedia Britannica doesn’t serve
author’s purpose. A large part of DNA is junk, not used by the body, and
it’s called parasitic or non-coding DNA. To establish the analogy of the
Encyclopedia Britannica with DNA, we’d have to say that of the 12
volumes of Encyclopedia Britannica, 2 contain meaningful information
while the rest of the 10 contain gibberish like ABICLDIXXGGSDLL. Taking
a lead from the argument above, we must maintain that whoever placed the
information in DNA must be half mad. But lets resist the urge of
oversimplification.
The argument is still a form of
personal incredulity. It is, “since I can not fathom how such complex
information could have been created thru an unguided, unintelligent
process, there must be a God”. Please note there are no other
possibilities presented or pondered. Why haven’t I ever seen someone
saying, “this DNA thing is too organized to have come up randomly so
there must be a superior alien civilization somewhere in the universe
that created us”? Or, “this DNA thing is eerily similar to computer
programs. That damn movie Matrix must be right”. Not only that, if a
Christian looks at the apparent design, he/she doesn’t go, “hey, there
is definitely a design which opens up the possibility that Vishnu
exists”. I haven’t seen anyone saying that because the flow of the logic
is not to deduce a conclusion from argument but to shape the argument to
reach a pre-decided conclusion. There is apparent design so there must
be a Yahweh/God/Allah who talked to Moses/Christ/Muhammad so I must
believe in Old Testament/New Testament/Koran. Does that seem like a logical
flow of deductions to you? Isn’t it interesting that
the same evidence that leads Philip Johnson to believe that Jesus was
Son of God, leads Harun Yahya to believe that he was just a prophet and
leads Gerald Schroeder to believe that both Johnson and Yahya are wrong?
I suspect that all the intelligent design proponents are doing is trying
to validate their pre-held beliefs but making it sound like they are
reaching there thru some intellectual discourse (I used to do that with
salt analysis in chemistry labs. First ask/bribe the assistant
what salt was it and then perform the experiments to “find out”). I
don’t know whom they are trying to deceive, others or themselves. Many
people have told me that they first looked at evolution and didn’t find
the theory probable and then they compared the religions and found that
x was the best option out there when they know that that’s not how it
happened. They didn’t FIRST look at evolution and while they were
looking at it (if they ever actually did), their God was looking over
their shoulders to make sure they don’t spend enough time finding out
all the details. And when they rejected it, they, quite miraculously,
ended up adopting the religion that they were born into in the first
place. Anyway, back to the article.
The argument is that DNA is
organized like a book containing information and since every book leads
to an intelligent author and not an unintelligent process, there must be
a God. This makes my life very easy. All I have to do is to write a book
thru a process that has no intelligence pertaining to the contents of
the book. I will demonstrate how it can be done. In fact, what I am
going to do is to write every book in the history, and that includes
future as well, on all the topics like psychology, architecture,
mechanical engineering, things that I know nothing about.
Is that a crazy claim?
Apparently yes, but not with enough resources. Here is how.
Lets say that an average book
contains 100 pages and an average page contains 500 letters (letters,
not words). That would mean that an average book contains 50,000 letters
in it. Please note that these are arbitrary numbers and you can replace
them with other numbers and it won’t affect the end-result.
Lets establish a character set.
A character set is a set of characters that can possibly be in a book.
Lets say the set contains all the English alphabets, A to Z, all the
digits, 0 to 9, all punctuation marks, all currency signs, all
scientific signs and a character that we call space. Lets say, for the
arguments sake that the set totals 256 characters.
Now, lets write our first book.
Pick the first character in our set and write it down 50, 000 times.
Lets say that first character is A. Our first book contains 50,000 A’s;
a stupid book but a necessary start to our process.
Our second book will resemble
very closely to our first book with only a single difference. Instead of
50,000 A’s, it will contain 49, 999 A’s. The last character in our book
will be B. The next book will be exactly the same except for the last
character, which now will be C. After we exhaust the 26 alphabets, lets
proceed to the other characters in our character set. Following is a
table to save me from typing

If you look at it closely, its
like the odometer of your car. Only that instead of 5 or 6 wheels, this
odometer has 50,000 wheels and instead of 10 digits per wheel, every
wheel has 256 characters. Rest is the same. So when you drive this car
with this imaginary odometer for 25650000 miles or
kilometers, you’d have scrolled thru all the 100 pages books that were
ever written or will be written in future.
If I program a computer with
that kind of computing power and ask it to print every one of those 25650000
volumes, you’ll have a library that will contain every book in history.
Most of it would be junk (like our DNA) but not all. Did I
say every book? What about a book of 200 pages? Well, it won’t be
there in one volume but there will be a part one, containing first 100
pages and a part two containing rest of the pages somewhere in this
cosmic library. That’s still not every book. What about a book written
in Persian? True, it won’t be there, but its English translation would
be. And if you want it to include the Persian books, all you need to do
is to increase the character set and you’ll have all the Persian books.
So this library contains all the
books written on Psychology by Dr. Khalid Sohail, including the ones
that he hasn’t even thought about writing so far by a process that knows
not the first thing about Psychology. This library would contain the
translations of Quran without knowing who Muhammad was. Not only that,
it would contain all the possible twisted and turned interpretations of
religious scriptures that people do to satisfy themselves that what they
believe in is the truth. You can’t blame me for not thinking about my
religious friends.
You might be thinking that this
process requires incredible amount of time and resources. That’s true,
it does. Nature had those kinds of resources and 4 billion years to come
up with the biosphere we are looking at today which, in my opinion, is
complex but not flawless. The process that I described to create the
cosmic library is not very efficient. Natural Selection, the force that
leads evolution, is much more cost effective than my process. Please
note that I didn’t impose any “selection pressure” on the books. Neither
is there kinship between books or an arms race between them or
aggression towards other books. All of these factors help natural
selection to make the process much more efficient to produce much better
results with lot less resources. With a little tweaking, I can introduce
some of that in the process but I think I have flogged that horse enough
for now.
Creationists at this point like
to talk about the intelligence of the process. Well, that’s a whole
another debate. I just wanted to tackle the claim that a book can’t come
about without an intelligent author thru a blind process and the process
that wrote those books is not intelligent by any definition of the word.
If that process is intelligent than the odometer in my car is also
intelligent.
Mr. Yahya writes:
“Evolutionary biologists have failed to realize that
they work with two more or less incommensurable domains: that of
information and that of matter… These two domains will never be brought
together in any kind of the sense usually implied by the term
"reductionism." …The gene is a package of information, not an object...
In biology, when you're talking about things like genes and genotypes
and gene pools, you're talking about information, not physical objective
reality... This dearth of shared descriptors makes matter and
information two separate domains of existence, which have to be
discussed separately, in their own terms”
I fail to see what Mr. Yahya
means. Evolutionary biologists do not realize that gene is information
as well as a physical object? What the heck have I been reading all
these years? You mean Mayr, Dawkins, Gould, Ridley, Patterson and the
plethora of the evolutionary biologists have only been pretending
that they know that gene is a package of information as well as a
physical reality? The author must be talking about evolutionary
philosophers who say crazy things, not biologists. And what is
“reductionism”? I have seen this term bandied about but never understood
what it means. It seems like some philosophical insult because once
somebody is pronounced “reductionist”, it seems to settle the argument
in the favor of “non-reductionist”.
If you go to a pebbly beach, you
will see a certain order in which the pebbles are arranged. The waves
would throw the pebbles in a somewhat organized manner. You will see
that the similar size pebbles will end up together. This must be because
of the intelligent design, right? The waves must be carrying some
information (at atomic level like the atomic weight of water), which
interacts with the information stored at the atomic level in the pebbles
on how to order the pebbles which makes the waves and pebbles
information carrying physical objects. I don’t think so. I think its
happening because of simple laws of physics. But then I must be a
reductionist.
Mr. Yahya than spends most of
the article dealing with materialistic philosophy, which I am not
interested in to respond. As for evolutionary biology, there are two
remaining points that I would like to answer.
Mr. Yahya quotes from Philip
Johnson and labels him “a leading critic of Darwinism”. This is the
second time Philip Johnson, an evangelical Christian lawyer, has found
his way into this discussion (first he was quoted by Mr. Don Joshua) so
I think he deserves my attention. Regardless of what an author believes
in or his/her ideological position, the most fundamental trait that I
look for in an author is honesty. I am really sorry to say that Philip
Johnson lacks that fundamental trait. I have, in front of me, his most
famous book “Darwin on Trial” and I am just going to quote two instances
of his dishonesty.
1- on page 9 in the first
chapter of his book, Johnson writes, “according to [Colin] Patterson,
Darwin's theory of natural selection is under fire and scientists are no
longer sure of its general validity”. On the next page he writes,
“Patterson suggested that both evolution and creation are forms of
pseudo-knowledge”. For reference Philip Johnson points to a speech Colin
Patterson made at the American Museum of Natural History (AMNH) in 1981.
This museum is my usual stomping ground and I went to their library and
read the speech referred by Johnson. The speech was not about theory of
evolution at all. It didn’t even mention theory of evolution. Its about
taxonomy. Its about the science that allocates names to species. That is
why Philip Johnson refrained from giving actual quotes from the speech
and instead provided his own dishonest summary.
2- I don’t have to go too far
for the next one. On page 11, Johnson quotes Stephen
Jay Gould and says that the neo-Darwinian synthesis, according to
Stephen Gould, “as a general proposition, is
effectively dead, despite its persistence as textbook orthodoxy." The
quote is taken verbatim from Gould’s article in Paleobiology from its
June, 1980 issue. Any evolution student will fall out of his chair
reading this. Gould, one of the most vocal proponents of neo-Darwinism,
is proclaiming it dead? Not really. Here is the full quote, including
the starting part of the sentence that Philip Johnson omitted:
“if [biologist Ernst] Mayr's
characterization of the synthetic theory is accurate, then that theory,
as a general proposition, is effectively dead, despite its persistence
as textbook orthodoxy.” Here is the quote from Mayr that Gould is
talking about, “The proponents of the synthetic theory maintain that all
evolution is due to the accumulation of small genetic changes, guided by
natural selection, and that trans-specific evolution is nothing but an
extrapolation and magnification of the events that take place within
populations and species.” What Gould is referring to is the last part of
the Mayr’s sentence that deals with “trans-specific evolution” That is a
disagreement based on what we call “Punctuated Equilibrium” that deals
with the mechanism of evolution but Philip Johnson is treating it as
Gould had issued a sentence of death to the theory of evolution.
If this is the
quality of arguments of “a
leading critic of Darwinism”, one can only guess what would be the state of
arguments from the
non-leading critics.
Mr. Yahya writes:
“The discovery of this fact [information in DNA] has
sent materialist philosophy and Darwinism, its application to the
natural sciences, into a dead end”
Oh really? And what maybe the
reason of that?
“because materialist philosophy claims that matter
forms all living things alone and that genetic information appeared
somehow by "chance." This is like saying that a book could be formed
from a random assemblage of paper and ink”
What’s wrong with the above
assertion? Lets read again with the added emphasis
“The discovery of this fact [information in DNA] has
sent materialist philosophy and Darwinism, its application
to the natural sciences, into a dead end, because
materialist philosophy claims that matter forms all living
things alone and that genetic information appeared somehow by "chance."”
First of all, saying that
evolution claims that genetic information appeared by “chance” shows
author’s ignorance about theory of natural selection but that’s not the
biggest blunder in the above sentence.
Darwinism is not the
application of materialist philosophy to the natural science. It’s
not the application of any philosophy. Its hard science. I know
that philosophers like to think that they are the holders of supreme
knowledge but I take exception to that idea. The only thing hard science
follows is facts, not this or that philosophy. The only way you can
falsify a scientific theory is thru facts, not some philosophical word-play. The main assertion that somehow the DNA information is a lethal
blow to Darwinism is so naiive that it borders on the ridiculous. DNA actually answered the questions Darwin himself struggled
with and conceded that he had no answers at that time. Don’t take my
word for it. Ernst Mayr, Professor Emeritus in the museum of Comparative
Zoology at Harvard University writes in his book “What Evolution Is” on
page 112 [emphases added]
“In 1953 Watson and Crick
discovered the structure of DNA, and after this major discovery followed
the other, culminating the discovery of the genetic code by Nirenberg in
1961. Finally, every step in the translation of genetic information in
the course of the developing organism was understood in principle.
Unexpectedly, the basic Darwinian concepts of variation and selection
were not affected in any way. Not even the replacement of proteins by
nucleic acid, as the carriers of genetic information required a change
in the evolutionary theory. On the contrary, an understanding of the
nature of genetic variation greatly strengthened Darwinism.”
Well, maybe, since I do not
know, Mr. Yahya’s biological credentials are more impressive than Ernst
Mayr so lets ask ourselves this question: if the discovery of
double-helix DNA was such a profound blow to Darwinism, the people who
discovered the double helix (James Watson and Francis Crick) and got a
Nobel prize for that must be the first one to realize that. Well, that’s
a NO. Pick up Watson’s book “DNA: The Secret of Life” and Crick’s “What
Mad Pursuit?” to see for yourself. Writing
in Nature magazine in May 1973, Crick wrote: “Darwinian evolution was
only a theoretical frame-work before 1953. We validated it as a fact by
our discovery of DNA”.
As for his co-discoverer, James
Watson, the following is what he said in an interview to Academy of
Achievement in October 1991
“Evolution only
occurs by creating variants, and a lot of variation is harmful to the
individual who carries it. So evolution is not a kind thing, and we're
all products of evolution. Well society, you know, says we're products
of God. We're products of evolution and it's very different. You know, a
just God wouldn't have done anything, which didn't have a purpose. But I
think like most biologists, we don't think there's anyone to answer our
prayers and change the course of destiny. So, I mean, scientists and
doctors, you know, have this right of change -- have this ability to
change the future. In that sense we are the gods, and people are, of
course, afraid of evil gods, and then for some people, you know, my way
of speaking right now is just totally inappropriate and sacrilegious,
and you know, in some countries they'd shoot me, or just -- You know,
saying there's no one up there in the heaven telling us what to do, but
I don't think there is. “
I guess Watson and Crick, even after almost 40
years of their discovery and even after the human genome
project, didn’t realize the implication of their discovery and remained
evolutionists. It was only up to Mr. Yahya and Philip Johnson to break
the news to them.
Mr. Yahya goes on:
“Israeli scientist Gerald Schroeder who studied
physics and biology in universities like the Massachusetts Institute of
Technology (MIT),”
Did he? Schroeder
is not trained in biology. Anyway, I need not say anything regarding his
claims since Mark Perakh has written a very good review of his books at
http://www.talkreason.org/articles/schroeder.cfm
And obviously, I don’t feel any
particular urge to comment on the part that deals with the preserved
tablet. Apparently, Quran can tell you whatever you want it to. It
serves as the conjurer’s hat in the hands of intellectuals who keep
pulling all sorts of rabbits out of it.
In the conclusion, the discovery
of DNA, far from what Mr. Yahya claims, gave a resounding affirmative
answer to Darwin’s theory of evolution. Darwin was frustrated when he
was asked how the variation happened. He always answered that he didn’t
know how it happened. DNA’s discovery answered that question; it happens
thru mutation in genes, a simple copying error in the mechanism of
duplication. Currently, there are many raging debates going on between
evolutionary biologists on topics such as Punctuated Equilibrium that we
visited earlier but they are all within the framework of the general
theory of evolution. Taking advantage of those conflicts to state that
the evolutionary biologists don’t know anything what they are talking
about is unfair and, to some extent, dishonest. In their frustration,
creationists tend to equate evolutionary theory with religion saying
that since both are unproved entities, they must be equally faith-based.
Sorry, but I don’t see the parallel. Whenever I am presented with a
theory, the first thing I see is what it offers as tools of its own
falsification. If you read “Origin of Species” by Charles Darwin, you
will find him telling you on many places how can he be proven wrong. He
states many times that if you discover a modern mammal fossil from more
than 500 million years ago, his theory would absolutely break down. If
you prove that acquired characteristics are inherited, or you see a species that can’t be perfectly nested
within its taxonomical group, theory of evolution will be proven wrong.
Darwin has provided many breakdown points like that in his book. Show me
a religious scripture doing that. One of my creationist friends once
told me that if someday its shown how spontaneous life can emerge, he
would stop believing in creationism. I asked him if he was sure and
wouldn’t he say that, yes, life was born spontaneously but that is how
God meant it to be? His answer was a smile and that’s it. That’s the
power of faith. No matter how many times evolutionists deal with these
rehashed arguments, faith is not going to breakdown. But, to repeat what
I wrote earlier, the only thing that can prove evolution wrong is
scientific facts and not some fancy philosophy because that’s not where
evolution is based; its based in hard scientific facts.
