Evolution: The Walking Dead?




If macro-evolution is a fact, this should be illustrated by the fossil record and how its patterns of common descent are paralleled by accompanying genetic similarities. In other words, common structures should have common genes if common descent is a reality. We should be able to detect a genetic and morphological pattern of lineal descent, not a hodge-podge of common traits (homologies) or structures found in unrelated species.

This assumption is so fundamental to the theory of evolution that Linus Pauling and Emile Zuckerkandl predicted that there would be no difficulty in demonstrating that common structures and their assumed common ancestry – as reflected in the Darwinian tree of life – should coincide with the tree of life generated from molecular (genetic) studies:

  • If the two phylogenic trees [one constructed based on common morphology and the other on common genetics] are mostly in agreement in respect to the topology of branching, the best available single proof of the reality of macro-evolution would be furnished. (Evolutionary Divergence and Convergence of Proteins, 1965, 101)

While the undertaking was reasonable, the results were damning. Biochemist, W. Ford Doolittle confessed:

  • Molecular phylogenists will have failed to find the “true tree,” not because their methods are inadequate or because they have chosen the wrong genes, but because the history of life cannot properly be represented as a “tree.”

  • It is as if we have failed at the task that Darwin set for us: delineating the unique structure of the tree of life.

Doolittle’s conclusions agree with those of many other biochemists. Michael Syvanen had examined 2000 genes across different phyla in an attempt to establish a lineal consistent pattern or tree. However, he found that different genes told “contradictory evolutionary stories”:

  • We just annihilated the tree of life. It’s not a tree any more; it’s a different topology entirely.

Casey Luskin summarizes these dismal findings:

  • Biological similarity is constantly being found in places where it wasn’t predicted by common descent, leading to conflicts between phylogenetic trees. (Salvo, Issue 27, 50. All of these quotations have been taken from Luskin’s article.)

If this is true, this undermines the evolutionist’s claims of common descent based on either common morphology or common molecules. But how extensive is this problem? Luskin cites a 2012 paper that claims that it is truly extensive:

  • Phylogenetic conflict is common and frequently the norm rather than the exception.

Luskin cites another paper from the journal of Biological Theory (2006):

  • Overall similarity reflects degree of relatedness…Review of the history of molecular systematics and its claims in the context of molecular biology reveals that there is no basis for the “molecular assumption.”

“No basis?” However, Darwinism requires a tree – molecular and morphological - that can illustrate some kind – any kind - of lineal descent! No tree, no evidence of common  descent! But the tree seems to be non-existent. Then, perhaps also macro-evolution?

Is the theory of evolution a dead man who is still walking, meanwhile threatening and banishing opposition, in a vain attempt to circumvent its inevitable demise?

John Sanford and the Utter Failure of the Theory of Evolution




Plant geneticist Dr John Sanford, research scientist at Cornell University, co-inventor of the gene gun, and author of Genetic Entropy and the Mystery of the Genome, had been a true believer:

  • I was totally sold on evolution. It was my religion; it defined how I saw everything, it was my value system and my reason for being. Later, I came to believe in God…I would not say that science led me to the Lord (which is the experience of some). Rather I would say Jesus opened my eyes to His creation—I was blind, and gradually I could see.
  • On a personal level this was a time of spiritual awakening, but professionally I remained “in the closet”…So I felt the need to take temporary leave from academia and institutional science because of the tension I felt in this regard, and the enormous potential hostility I sensed from my academic colleagues. I think the academic environment is very hostile to the very idea of a living and active God, making it almost impossible for a genuine Christian to feel open or welcome.
Eventually, Sanford’s new-found faith led him to re-examine the “evidential foundation” for the theory of evolution, and found that it was virtually non-existant:

  • Institutional science has systematically “evolutionized” every aspect of human thought. Contrary to popular thinking, this is not because evolution is central to all human understanding, but rather has arisen due to a primarily political and ideological process. Consequently, in the present intellectual climate, to reject evolutionary theory has the appearance of rejecting science itself. This is totally upside down…We cannot really explain how any biological system might have “evolved”, but we can all see that virtually everything we look at has extraordinary underlying design.
  • I am not aware of any type of operational science (computer science, transportation, medicine, agriculture, engineering, etc.), which has benefited from evolutionary theory. But after the fact, real advances in science are systematically given an evolutionary spin. This reflects the pervasive politicization of science.’
He subsequently concluded that evolution into more complex forms is impossible. For one thing, mutations are the source of de-evolution (the corruption of the genome) and not evolution:

  • Mutations are word-processing errors in the cell’s instruction manual. Mutations systematically destroy genetic information—even as word processing errors destroy written information. While there are some rare beneficial mutations (even as there are rare beneficial misspellings), bad mutations outnumber them—perhaps by a million to one. So even allowing for beneficial mutations, the net effect of mutation is overwhelmingly deleterious. The more the mutations, the less the information. This is fundamental to the mutation process.’
Sanford also concluded that natural selection does little to slow the de-evolution process:

  • Very rarely a beneficial mutation arises that has enough effect to be selected for—resulting in some adaptive variation, or some degree of fine-tuning. This also helps slow degeneration. But selection only eliminates a very small fraction of the bad mutations. The overwhelming majority of bad mutations accumulate relentlessly, being much too subtle—of too small an effect—to significantly affect their persistence. On the flip side, almost all beneficials (to the extent they occur) are immune to the selective process—because they invariably cause only tiny increases in biological functionality.
  • So most beneficials drift out of the population and are lost—even in the presence of intense selection. This raises the question—since most information-bearing nucleotides [DNA ‘letters’] make an infinitesimally small contribution to the genome—how did they get there, and how do they stay there through “deep time”? Selection slows mutational degeneration, but does not even begin to actually stop it. So even with intense selection, evolution is going the wrong way—toward extinction!’
Sanford concludes that:

  • The bottom line is that Darwinian theory fails on every level. It fails because: 1) mutations arise faster than selection can eliminate them; 2) mutations are overwhelmingly too subtle to be “selectable”; 3) “biological noise” and “survival of the luckiest” overwhelm selection; 4) bad mutations are physically linked to good mutations, so that they cannot be separated in inheritance (to get rid of the bad and keep the good). The result is that all higher genomes must clearly degenerate. This is exactly what we would expect in light of Scripture—with the Fall—and is consistent with the declining life expectancies after the Flood that the Bible records.
Sanford is not alone. Many evolutionists share Sanford’s assertions about the problems with evolution. All the following quotations are taken from John Lennox’s masterful book, God’s Undertaker: Has Science Buried God:

  • “There is no theoretical reason that would permit us to expect that evolutionary lines would increase in complexity with time; there is also no empirical evidence that this happens.” (John Maynard Smith, E. Szathmary)
  • “In the whole experimentally accessible domain of microevolution (including research in artificial breeding and in species formation), all variations have certainly remained within the confines of basic types [species, more or less].” (Siegfried Scherer)
  • Cell biologist E.J. Ambrose of the University of London argued that it is unlikely that fewer than five genes could ever be involved in the formation of even the simplest new structure, previously unknown in the organism. He then points out that only one in 1,000 mutations is non-deleterious, so that the chance of five non-deleterious mutations occurring is 1 in a million billion replications. [This means that every organism will probably die before it adds a new organ!]
Nor is there any experimental evidence to counter-balance these assessments:

  • In his book, Grasse observed that fruit flies remain fruit flies in spite of thousands of generations that have been bred and all the mutations that have been induced in them…More recent work on the E. coli bacterium backs this up. In this research no real innovative changes were observed through 25,000 generations of E. coli bacterium. (Lennox, 108)
Lennox also informs us that the fossil record, citing many evolutionists, “gives no good examples of macroevolution.” Perhaps it’s time to reconsider the design hypothesis!

The Theory of Evolution cannot be Refuted!


We have a tremendous capacity to believe what we want to believe. It seems that God has given us this capacity to sin by merely sticking our heads in the ground and denying the obvious. Consequently, the Book of Proverbs laments that, “All the ways of a man are clean in his own sight” (16:2).

I marvel at evolutionists who claim that there is no evidence against their theory of evolution and that it is already a “proven fact.” How can they be so blind! Well, we can rig the rules of the game so that all of the facts can be lined-up in support of our theory.

For example, the persuasiveness of Darwinism rests on this one idea: commonalities – genetic, fossil, and morphological – prove common descent. However, Darwinists are also ready to admit that there are an abundance of examples of commonalities that clearly are not the result of common descent. On his blog, biologist Cornelius Hunter mentions one of them:

  • By now this must seem tedious, but there is…evolution’s endless stream of failed expectations. This time it is striated muscles, in bilaterians and non-bilaterian eumetazoans. They seemed to evolutionists to have a common evolutionary origin. But now the molecular differences do not support that expectation. Instead, the considerable similarity across these various species would likely have arisen independently, via those random mutations. But evolutionists forget about this long list of false expectations. Evolution must be a fact, regardless of the evidence.
However, many evolutionists are unconcerned about this gaping hole in their theory. When commonalities are clearly not the result of common descent, they merely call these instances “convergent evolution.” This means that the many commonalities are the result of something else, but they are quick to assure us that these puzzling commonalities are the result of common evolutionary pressures. For instance, birds and insects both fly because of the common pressures to either find food or to escape enemies. In other words, if they can explain how common structures are the result of common descent, they again “win,” and if they can explain how these structures are the result of common pressures, they again “win.”

How then can they loose? Well, they can’t! Heads, I win; tails, you loose!
