darwinAs a biology teacher I am constantly bombarded by the never-ending conflict between the forces of Creationism and the minions of Evolution. It becomes a new adventure in conflict management each year. Occasionally it becomes difficult as my own personal views enter the conflict and so I have chosen this opportunity and venue to present my own opinions.

As a committed Christian I am disinclined to embrace the scientific view that all life began as a random combination of chemicals in some primordial sea. It is, however, on rational grounds that my strongest objections are based.  The theory of Spontaneous Generation is described as “the hypothetical process by which living organisms develop from nonliving matter; also, the archaic theory that utilized this process to explain the origin of life. According to this theory, pieces of cheese and bread wrapped in rags and left in a dark corner, for example, were thus thought to produce mice, because after several weeks there were mice in the rags. Many believed in spontaneous generation because it explained such occurrences as the appearance of maggots on decaying meat.”   The theory was refuted completely in the 18th century and yet here we are in the supposedly enlightened 21st century, embracing the same idea. A combination of simple chemicals somehow mixes together with no outside influence beyond lightning or sunlight to form life.  The animate springs from the inanimate.  We are unable to duplicate or observe this phenomenon of generating life.  All efforts have been unsuccessful.  (See the Bubble Theory and the Primordial Soup Theory by Stanley Miller and Harold Urey).  No matter how many eons of time pass, the chemicals just don’t mix to form the necessary proteins.  Contrary to popular opinion, life doesn’t just happen, thus the necessity of a prime mover.

I have no difficulty with the idea of Natural Selection.  Selective breeding and its results are an observable and replicable phenomena.  We have changed many species to fit our wishes using nothing but selective breeding.  It stands to reason that if we can create a breed of horses only a few inches tall by breeding small horses to small horses then in nature, the continued breeding of the strongest, fastest, and smartest organisms would reinforce those traits and the genes responsible for them and by this process a species may be improved and even change its appearance.  However,  the miniature horses we produce are still horses.  They can still breed with normal horses and produce viable offspring.  Their chromosomes still match up with any other organism of the species Equus ferus caballus.  Chihuahuas and Great Danes are all still genetically compatible.  They are all biologically the same animal. Selective breeding, whether natural or otherwise, can improve a species or modify a species but it can not transform one species into another.  Selective breeding can change the frequency of alleles that already exist but it can not create new ones or remove old ones.  Selective breeding can make a bigger dog or a smaller dog or a faster dog, but it can not make a dog into a cat.

It is said the mutation is the source of drastic genetic change and I agree.  However, one of the by-products of Hardy Weinberg is that recessive alleles can never be bred out of a population.  The recessives continue no matter how much the dominant genes improve an organism’s chances of survival.  Should a dominant positive mutation occur, the original recessive stock should still exist as well.  Those gene frequencies can be reduced but can never be completely removed from the population.  Should mutation lead to man and monkey, the origin species of the mutation should still exist.  Mutation and Natural Selection are not enough to cause extinction.  Also, in the end, mutation is a universally destructive process.  Genetic mistakes in the form of Huntington’s Chorea, Spina Bifida, Turner’s Syndrome, and the like are all too common in our world.  The X-men, on the other hand,  have yet to make an appearance.  Given the general degradation of the natural environment and the prevalence of harmful chemicals in the air, water, and soil, the occurring of mutants is becoming more and more common and  the chances of a positive mutant decline daily.

According to Schleiden, Schwann and Virchow, all living things are composed of, and give rise to offspring composed of cells.  Cells are the fundamental functional, as well as structural, units of all organisms, and the ONLY place cells can rise from is another cell.  I accept that with only one concern.  Given that life on Earth began at some point AFTER the Earth came to be, where did that original cell come from?  Cells as a vehicle for DNA and heredity are the only forms of life that we can find any record of, or can even imagine.  Absolutely no evidence of any other form of life can be found within the fossil record or in extant species.  As with spontaneous generation, cells don’t just happen.  The structures are too complex and precise to have just spun up from nothing.  Cells are orderly and elegant structures.  The idea that they could have somehow come to be spontaneously by trial and error is chaotic and messy.

Well there you have it.  This is my justification for my beliefs.  Please don’t bother to comment on how backward, misinformed, or deluded I am and I will not remind you of your ultimate destination when you leave this world for the next.  In the end, the only thing we can be certain of is that we do not and can not know what really happened.  The scientific method requires duplication and repetition to validate a theory.  As these things have not been possible and continue to be impossible, so validation or proof remain beyond us.  An honest scientist will refer to evolution and its attendant ideas as theories and it is only the sensationalist and pseudo-intellectuals who declare them to be absolute truth.  Matters of faith, on the other hand, require no such validation.  Faith allows the surrounded and defeated soldiers of the Alamo to turn aside the attack of a much larger army.  Faith persuades the martyr to face lions and tigers and bears (oh my) rather than renounce their beliefs.  Faith powers revolutions, creates heroes and moves mountains.  Only a fool discounts or denies the efficacy of faith.
