[Editor’s note: In June 1990 The John Ankerberg Show
taped a series of interviews with men from several branches of the
sciences regarding the evidence for creation. For technical reasons we
were unable to air these interview. Nevertheless, we have decided to
release portions of these interviews in a series of articles so you
could read the arguments that were being made at that time—more than a
decade ago.
Considerable effort has been made to quote the
gentlemen correctly. We have attempted to find the correct spelling of
the scientific terms used. However, the reader should keep in mind
that this is a transcription of oral interviews. Mistakes in spelling
and in the technical language should be laid at the feet of the
editor.]
Dr. John Ankerberg: I want
to begin by talking about the origin of life. How did life begin on
earth? My first guest is Dr. Duane Gish who received his Ph.D. from
the University of California, Berkeley in 1953. Dr. Gish, give us the
two difference models. What is the evolutionary model saying today and
what is the creationist model?
Dr. Duane Gish: John,
according to the evolutionary model or evolutionary theory, concerning
the origin of life, life arose through processes which were strictly
naturalistic, mechanistic, according to properties inherent in matter.
That is, no intelligence was involved; God was not involved; no
outside agency was involved. Now I want to emphasize that certainly
not all evolutionists are atheists, but that theory is non-theistic.
God simply was not involved; it was not necessary.
According to this theory on the hypothetical
primordial earth there were simple gases, perhaps something like
hydrogen, ammonia, and methane, and nitrogen, and carbon dioxide and
carbon monoxide and things like that. And by the interaction of raw
energy such as lightning and ultraviolet light converted the simple
chemicals to more complicated chemicals such as amino acids, which are
the building blocks of proteins, and the nucleotides, which are the
building blocks of DNA and RNA. And then somehow, through strictly
spontaneous natural processes, these building blocks combined with one
another.
Not only did they combine with one another, but
somehow through pure chance meaningful molecules arose: a DNA molecule
that supposedly contained information and that information could be
then transcribed and translated into a protein molecule which could do
something meaningful. And then these molecules dissolved in the
hypothetical primordial ocean, somehow assembled themselves into a
living cell, with membranes and energy factories, and protein
factories and all these metabolic cycles that are necessary for life.
And this all happened spontaneously without any intervention of any
outside agency.
Now the creation scientist says no, that is not
possible. We don’t see anything like that happening in nature. We
don’t see things assembling spontaneously in any meaningful way. But
the evolutionist says, "There was an informational molecule there with
information in it." Now the creation scientist says, "If there is
information there, that has to be imposed from the outside."
Ankerberg: Talking about
DNA, Dr. Francis Crick was the Nobel Prize winner and biochemist and
co-discoverer of the structure of the DNA molecule. And he said in his
article, "Life Itself," page 88, "An honest man armed with all the
knowledge available to us now could only state that in some sense the
origin of life appears at the moment to be almost a miracle, so many
are the conditions which would have had to have been satisfied to get
it going." Now, Dr. Gish, what did Francis Crick mean by that
statement?
Gish: Well, when we look
at the alleged self-assembly of these molecules, and then the assembly
of these molecules supposedly into a self-replicating,
self-maintaining entity called life, the probability of that happening
through natural processes is so infinitesimally small that you would
ordinarily ascribe that to a miraculous cause.
And you know, John, the more we learn about life,
the more we understand the processes involved, the more miraculous it
becomes. When I was in college, for example, we thought that the
synthesis of the DNA molecule was a rather simple thing. You have the
nucleotide triphosphate, you have a polymerace and then put it
together. We know now however, that the synthesis or replication of
DNA molecule involves at least twenty different proteins, many, many
enzymes and other factors. It is vastly more complex than we thought
then. And as we study life and understand more about it we’ll find
that it is even vastly more complex than we believe today.
Ankerberg: I read in the
newspaper, "In the human body, DNA programs all characteristics such
as hair, skin, eyes and height. DNA determines the arrangement for 206
bones, 600 muscles, 10,000 auditory nerve fibers, 2 million optic
nerve fibers, 1 billion nerve cells, 400 billion feet of blood vessels
and capillaries..." and so on. So, this is just what this does. Now
what’s the problem chemically, biologically if you want, to get that
thing together?
Gish: Let me add just a
little bit to what you’ve said, John. The human brain contains about
12 billion brain cells, and since each brain cell is connected to
10,000 other brain cells, that means that there are about 120 trillion
connections in the human brain. Now, that information, how this must
be put together, is coded somewhere. We know how the DNA sequence
codes for protein. We know that. But we don’t know why you have blue
eyes and I have brown eyes, while you’re maybe tall, I’m short, or
something like that. We have no idea, really, where that information
is. So we know really very little about the genetic system, except
that we know that it is incredibly complex.
Now, about your question. Let me start out by
emphasizing what information is. I have a book here and we say it
conveys information—there’s information here. Now, John, there is
absolutely no information here unless there is a human being to read
it. If every human being died tomorrow, there would be absolutely no
information in this book. So the very fact that there is information
here implies or requires that there is something able to utilize it.
Now first of all, we had to invent language and only
human beings do that. But once the language has been invented, we have
something we can use, then that language had to be put into this form
where the letters had to be arranged in precise sequence, the word had
to be right in certain sequence. And then we have information.
Much is the same with a living cell. We say that DNA
contains information. Well, there is absolutely no information in any
DNA molecule without a living cell that can read that information and
can utilize it and put it into use. And so, there must be information
there, but there must be an apparatus to utilize it.
Now the evolutionist believes the DNA molecule came
first and it had information. I maintain that’s absolutely, totally
false. The primitive ocean couldn’t care less what the sequence of
these nucleotides were. The only meaning is when there is machinery to
utilize it.
Let’s take a look first of all at the replication of
the DNA molecule—what that does involve and I can only say a few
things about it. First of all, there must be enzymes that unwind the
DNA molecule. The DNA molecule is a double-stranded molecule that must
be unwound, there is an enzyme that does that. Then there are DNA
polymeraces that put these nucleotides together in segments and there
is an enzyme that adds short primer segments to get this chain
assembly started. Then there are ligases that link the DNA segments
together. And there are many other enzymes involved. There are, as a
matter of fact, about 20 different enzymes in this synthesis of DNA
itself. You see, when any living organism replicates itself, or
reproduces, it must make copies of the DNA—its genes, you see. That’s
an incredibly complex machinery required to do that.
Now, we have then the so-called information in this
DNA molecule, in other words there’s a sequence of the units, we call
them nucleotides, the sequence of which tells the cell, say for a
certain protein, which amino acid is to be first, which amino acid is
to be second, which is to be third, and so forth, so we have a
biologically active molecule, such as an enzyme, or human growth
hormone or hemoglobin, the red blood protein, and so forth and so on.
Now, you see that information in the DNA molecule is found in the
nucleus, but where all the action takes place is out in the cell
itself, out in the cytoplasm. So, we’ve got to move that information
from the DNA somehow out into the cell.
That’s a very, very complicated process. First of
all, the information in the DNA molecule must be transcribed into an
information in what is called a messenger RNA. That requires quite a
complex apparatus. Then the messenger RNA moves to the ribosome,
contains ribosomal RNA. (By the way, a ribosome, which is absolutely
essential for the synthesis of protein, contains three RNA molecules
and about 55 different protein molecules.) The ribosome is very
complex, so we must have the information the DNA molecule transcribed
into the information in the messenger RNA which then moved to the site
of the ribosome and there it must cooperate with the ribosome.
Now how does this information get translated into
protein? Well, each individual amino acid which forms a protein first
must be linked to a transfer RNA, so there is another RNA molecule.
And there is a particular transfer RNA molecule for each particular
amino acid and there is a particular enzyme for each amino acid and
each transfer RNA that will link the particular amino acid with its
particular transfer RNA. So you have to have the transfer RNA, the
amino acid, and the particular enzyme.
Then after the amino acid has been linked to the
transfer RNA, that moves to the site where the messenger RNA is there
with the ribosome. Well, the transfer RNA then positions itself in the
proper place in the messenger RNA, where that amino acid to which it
is linked is supposed to go. Then you have another enzyme that links
the amino acid then to the growing protein chain, another enzyme that
cuts loose to transfer RNA and another enzyme that finally releases
the protein and many other enzymes. Now you see, it is incredibly
complicated machinery.
Now, where did this machinery come from? You see the
machinery had to be there to utilize that information. There could be
no information there until we had all this complicated machinery that
could utilize it, you see. Now the creationist says that that
information could not spontaneously produce itself.
This book was not produced by the ink and the paper
or a typesetting machine or a typewriter, you see. That’s an important
part of it, but it had to be done by intelligence. The creationist is
saying that the fact that there is information there and then there is
this very complicated machinery required to utilize that information,
that that had to come from the outside. It could not have arisen
spontaneously from within the system. And it’s a very, very compelling
argument. We believe that it’s more than persuasive; it’s coercive
evidence that life, you see, is the secret of DNA. DNA is not the
secret of life, but life is the secret of DNA.
Now, this information has been so powerful as you
quoted from Dr. Crick, who certainly is no believer, others have been
so persuaded, one of those is Sir Fred Hoyle, a famous British
astronomer. He, working with a friend, Professor Chandra Wikramasinghe,
also a very well known British astronomer, became interested in this
problem of the origin of life, and they calculated the probability of
life evolving on this planet in 5 billion years. Actually they
considered only a small part of it. The probability of getting, say, a
protein molecule together, or a DNA molecule together, they didn’t
even consider the probability of assembling all of this into a cell.
And their conclusions were that the spontaneous
origin of life is impossible. And as a matter of fact there was an
article which appeared in the August 14, 1981 issue of the Daily
Express in London about this statement by Hoyle and Wikramasinghe
and what they’ve said. After they had considered these possibilities
involved, they concluded, as Hoyle put it, "The probability of the
evolution of life is equal to the probability that a tornado sweeping
through a junkyard would assemble a Boeing 747." And Hoyle and
Wikramasinghe considered only a part of the problem—the problem of
putting nucleotides together in a meaningful sequence or amino acids.
They didn’t even consider the bigger picture of the origin of the cell
itself.
