Intelligent
Design, Part I
by Justin
Hart
"If
it could be demonstrated that any complex organ existed which could
not possibly have been formed by numerous, successive, slight modifications,
my theory would absolutely break down." (Origin of Species,
6th ed. (1988), p. 154) – Darwin
It’s understandable
that there exists a theological debate among differing religious
views. After all, religious understanding and belief derives its
momentum from faith-driven exercises rather than hard empirical
evidence. But one would expect scientific debate to avoid such
quibbles and disagreements in light of their own scientific method,
which does derive its momentum from hard empirical evidence.
Unfortunately, science is overseen by humans, and the same biases,
institutionalized thinking, and raw power involved with any human
venture are also present in science.
One debate,
looming large on the horizon, pits the “high priests” of evolution
against the proponents of “intelligent design.” In this article
I examine Intelligent Design and its claims against evolution.
Intelligent
Design
In
1802, William Paley penned his famous pocketwatch analogy. To wit,
if we find a pocketwatch in the desert we assume that some human
hand was involved and that the watch did not materialize through
some blind natural process. The analogy here is that the complexity
of nature points to an intelligent designing force.
This was the
prevailing scientific view until Darwin published his Origin
of Species in 1859. The evidence that Darwin asserted took
the scientific community by storm and evolution has been the prevailing
modus operandi since that day.
Evolutionary
biology teaches that all biological complexity is “the result of
material mechanisms.” In short, evolution claims that all things
came into existence by means of natural selection and mutation,
in minute “baby steps” of progression over millions of years. Organisms
adapt for conditions adding to their functionality piece by piece
until we are what we are today.
We should note
here that no one doubts natural selection as a robust scientific
theory. For example, a desert fox has developed longer ears over
time to help expel heat from his body. If this were all that evolution
purports, everyone would go home happy. Instead the debate turns
on Darwin’s theory that all species evolved from a handful of previous
species. Intelligent Design is a growing scientific movement that
challenges Darwin and his naturalistic legacy.
Intelligent
Design derives its impetus from systems that are “irreducibly complex.”
Here’s a common analogy that’s used to explain the theory.
An everyday
example of an irreducibly complex system is the humble mousetrap.
It consists of (1) a flat wooden platform or base; (2) a metal
hammer, which crushes the mouse; (3) a spring with extended ends
to power the hammer; (4) a catch that releases the spring; and
(5) a metal bar that connects to the catch and holds the hammer
back. You can't catch a mouse with just a platform, then add a
spring and catch a few more mice, then add a holding bar and catch
a few more. All the pieces have to be in place before you catch
any mice. [1]
According to
evolution, you should be able to reduce every biological system,
piece by piece, down to its beginning. Evolution then could not
be the scientific origin of the mouse trap, there must have been
some intelligent hand involved. As Darwin admits in our opening
quote, if you can demonstrate a complex biological system along
the same line of reasoning, then his theory would break down.
Bacterium
Flagellum
The
question then is this: Are there biological systems that exhibit
such complexity? One prominent example is that of bacterium flagellum.
Bacterium flagellum are whip-like appendages that move bacteria
throughout our body. These flagellum work very much like a motor;
each has a rotor, a stator, O-rings, bushings, and a drive shaft.
They are powered by the combination of 50 different proteins. These
proteins exist independently within the human body and come together
to power the flagellum. Take one of these proteins away, and the
flagellum fails to operate. The mathematical probability of these
50 proteins coming together under the theory of evolution is so
outrageous as to almost insist that there was some higher power
involved.
Plasmids
Plasmids
are circular pieces of DNA that can easily be exchanged among bacteria.
Plasmids can also confer antibiotic resistance. When one bacterium
releases a plasmid, another can absorb it, information from the
Plasmid is infused from one into the other. The problem begins
when we ask "where did the bacterium that released the plasmid
information in turn derive it?" Any evolutionary explanation
will be circular reasoning and insufficient to explain the matter.
Eukaryotic
Cells
Michael
Behe, one of the major proponents of intelligent design explains
another example:
Another example
of irreducible complexity is the system that allows proteins to
reach the appropriate subcellular compartments. In the eukaryotic
cell there are a number of places where specialized tasks, such
as digestion of nutrients and excretion of wastes, take place.
Proteins are synthesized outside these compartments and can reach
their proper destinations only with the help of "signal"
chemicals that turn other reactions on and off at the appropriate
times. This constant, regulated traffic flow in the cell comprises
another remarkably complex, irreducible system. All parts must
function in synchrony or the system breaks down. [2]
Blood Clotting
The
system that prevents our blood from clotting is yet another example.
Blood clotting consists of a complex cascade of enzymes and cofactors
which must be in place to work. The evolutionist’s rebuttal to
this is that blood clotting experiments on mice have removed certain
enzymes successfully. The Intelligent Design (ID) response is that
the mice in the experiment were detrimentally affected by the reduced
enzymes; which flies in the face of another evolutionary postulate:
the mutated change in an organism must benefit the organism (survival
of the fittest after all).
People, Places
and Theories
There
are a number of prominent players currently working on ID. Here
are a few bios and links that you can peruse:
Philip E.
Johnson, is
a graduate of Harward and the University of Chicago. He was a law
clerk for Chief Justice Earl Warren and has taught law for over
twenty years at the University of California at Berkeley.
Johnson's most
prominent contribution has been Darwin
on Trial which examines Evolution from a standpoint of sound
reasoning and scientific support.
Michael Behe
received his Ph.D. in biochemistry from the University of Pennsylvania
in 1978, is a professor of biological sciences at Pennsylvania's
Lehigh University. His current research involves the roles of design
and natural selection in building protein structure. His book Darwin's
Black Box: The Biochemical Challenge to Evolution is available
in paperback (Touchstone Books, 1998).
Behe is one
of primary proponents of ID. His book has been the focus of many
of the evolutionist’s rebuttal. Behe has been lambasted and harangued
for his viewpoints and his responses are mostly ignored by peer
publications. Hmm… sounds like a familiar brick wall.
William A.
Dembski, holds Ph.D.'s in mathematics and philosophy, is an
associate research professor at Baylor University and a senior fellow
with the Discovery Institute in Seattle. His books include The Design
Inference: Eliminating Chance Through Small Probabilities (Cambridge
University Press, 1998) and No Free Lunch: Why Specified Complexity
Cannot Be Purchased Without Intelligence (Rowman and Littlefield,
2001). links
Dembski is known
as the Isaac Newton of ID. He has taken informational mathematics
to calculate the probability of irreducibly complex biological systems.
He has also brought an historical perspective to the movement demonstrating
how evolution failed to adequately dismiss British natural theology.
Jonathan
Wells received two Ph.D.'s, one in molecular and cell biology
from the University of California, Berkeley, and one in religious
studies from Yale University. He has worked as a postdoctoral research
biologist at the University of California, Berkeley, and has taught
biology at California State University, Hayward. Wells is also the
author of Icons
of Evolution: Science or Myth? Why Much of What We Teach About Evolution
Is Wrong (Regnery Publishing, 2000).
Wells’ book
has approached ID from an attack vantage point. He details 10 major
flaws within evolution and shows how many supposed supports of evolution
are nearly fraudulent but are still taught in our schools. Wells
has been at the front of a debate in Ohio which is considering whether
or not to allow ID to be taught as an alternative to evolution.
Conclusion
We
should note that Intelligent Design is a theory just like Evolution
is a theory. The debate between the parties is raging on and may
eventaully reach a fervent pitch. Currently, several school boards
across the country are examing its validity to determine if they
should allow it to be taught in schools. Intelligent Design is an
exciting venture for us to examine. In the coming months I will
report on several books, theories and debates on the issue.
