Mutations And “Faded” Genes (Part 2)

Sunday, May 29th, 2011

In my previous post we were examining the claims of evolutionary theory which says that every living thing which exists is the result of an unguided process of natural selection acting upon random mutations.  The point that I emphasized was the fact that natural selection is powerless to create the very thing that is most needed-  new genetic information.  I ended by saying that the evolutionist would remind us that we are overlooking the most important factor of all-  mutations.

            So, do mutations have what it takes to save evolutionary theory?  It’s highly unlikely.  Just as with natural  selection, mutations cannot create any new information.  When asked if new information can originate through mutations, Dr. Werner Gitt, a director and professor at the German Federal Institute of Physics and Technology answered this way:

             “…this idea is central in representations of evolution, but mutations can only cause changes in existing information.  There can be no increase in information, and in general the results are injurious.  New blueprints for new functions or new organs cannot arise; mutations cannot be the source of new (creative) information.”

Gitt,W., In the Beginning Was Information, CLV, Bielefeld, Germany, p. 127, 1997

            It’s bad enough that mutations are not the “hero” that the evolutionist was hoping for.  To make matters worse, mutations actually turn out to be the villain in the story!  Not only do mutations lack the very thing that it takes to drive us forward in some onward, upward evolutionary direction, mutations are actually driving us irreversibly and inescapably in a direction toward decay and death.  In fact, mutations are the primary reason that all of us age and eventually die.  But not only do our bodies, individually, age and die, the overall effect of genetic decay (entropy) is that the entire human race is “aging” genetically and will eventually die.

            In order to understand why that’s the case, we need to understand what mutations are and how they work.  In short, mutations are “typographical errors” that occur in our DNA code as that information is replicated during cell division.  Similar to word-processing errors, mutations can occur as deletions, insertions, “letter substitutions” (point mutations), and inversions.  Just as errors in word-processing corrupt the meaning and integrity of a text, mutations corrupt genetic information.  As a result, the cumulative effect is that the genetic information necessary to build human beings is in a state of disintegration

            In his presentation, “The Mystery of Our Declining Genes”, retired Cornell University Professor Dr. John Sanford comments that a famous geneticist once stated that if the mutation rate was as high as one mutation per person, per generation, human extinction and human degeneration would be certain.  Dr. Sanford goes on to point out that current research in human genetics has confirmed that there are more than one hundred new mutations per person, per generation-  a fact that is well-known among human geneticists.  By the way, the “genetic mistakes” of each generation are passed along and added on to each successive generation.  In other words, each of us will have one hundred more mutations than our parents did.

            Evolutionists insist that it all makes sense once you include natural selection in the process-  that natural selection acting upon those mutations is the key to understanding evolution.  However, that explanation is entirely inadequate to salvage the theory.  For the most part, natural selection cannot select for “beneficial” mutations because they are extremely rare and much too subtle at the genetic level-  so subtle, in fact, that they are virtually “invisible” to natural selection.  On the other hand, natural selection has the additional problem of not being able to select against  (get rid of) bad genes for the same reason (too subtle to detect). 

            Here’s the problem:  Since nearly all mutations are harmful, and since most of them are so subtle that they go largely undetected by natural selection, the overall, cumulative effect on an organism is one of decay and disintegration.  Sanford compares the effect of harmful mutations to rust on a car.  The rusting of metal is a subtle process (one atom at a time) that takes place long before there are any visible signs, and  the overall effect is always destructive not constructive.  In addition to this, it’s important to keep in mind that natural selection cannot “pick and choose” between which genes it “likes” and which ones it “doesn’t like”.  It can only select the entire organism-  it must take the bad genes (the majority) along with the “good” genes (extremely rare by comparison).

            Dr. Sanford says that the declining condition of our genes is well known among human geneticists.  He goes on to say that he is puzzled by the fact that even though geneticists agree that the human race is degenerating, many of those same geneticists continue to believe in evolution despite evidence to the contrary.  What doesn’t surprise Dr. Sanford is why they withhold that information from the general public.  After all, it’s not easy to face up to the fact that the human race is dying, and dwelling on it can leave a person feeling hopeless and in a state of despair.

            However, the good news is that we are not the “byproducts of time plus matter plus chance”.  You and I were created by the purposive act of an awesome, all-powerful God-  the same God who sent His one and only Son, Jesus Christ, into this world to vanquish death and to offer eternal life to those who are willing to place their trust in Him.
