The Gene Myth

Biological variation is, in part, transmitted from parent to progeny. Tall individuals tend to have tall offspring, fast individuals tend to have fast offspring, and so forth. This transmission process is key to the action of natural selection. Those trait variations that are successful in transmitting themselves to the next generation, by definition, survived while those that failed would disappear from the population. So long as traits are transmitted, evolutionists argue that natural selection is inevitable.

In other words, whatever it is that determines your traits is also transmitted to your offspring. Therefore, if you have evolutionarily successful traits then you will have more offspring, and they will receive your successful traits.

But how are the traits defined and transmitted? Darwin didn’t quite know how but in the twentieth century it seemed obvious—via the genes. According to the merger of modern genetics and evolution, it was all in the genes. They determined your traits and they were passed on to your offspring. This view fit evolutionary theory and was quickly accepted as an unquestionable scientific fact.

There is only one problem: it is false.

The fact that our genes are practically identical with the chimpanzees genes should have been a sign to evolutionists that their gene-centric view was problematic. How could the chimp and human be so different if their genes are so similar? Nonetheless, evolutionists proclaimed the great similarity as evidence that there must be an evolutionary relationship between humans and chimps.

In fact the biological evidence is clear: genes are only part of a far more complicated story than what evolution envisioned. As Stuart Newman
explains:

Genes, which are composed of DNA, directly specify the sequences of RNA molecules and indirectly, the amino acid sequences of proteins. Before there were multicellular forms, single-celled organisms evolved for as much as two billion years driven, in part, by genetic change, as well as by establishment of persistent symbiotic relationships among simpler cells. During this entire period no cellular structure or function was specified exclusively by a cell’s genes. The protein and RNA molecules produced by cells associate with each other in a context-dependent fashion or, in many cases, catalyze chemical reactions (generating lipids, polysaccharides and other molecules), whose rates depend on the temperature and composition of the external environment. So the population of molecules inside the cell can vary extensively even if the genes do not.

It was long believed that a protein molecule’s three-dimensional shape, on which its function depends, is uniquely determined by its amino acid sequence. But we now know that this is not always true—the rate at which a protein is synthesized, which depends on factors internal and external to the cell, affects the order in which its different portions fold. So even with the same sequence a given protein can have different shapes and functions. Furthermore, many proteins have no intrinsic shape, taking on different roles in different molecular contexts. So even though genes specify protein sequences they have only a tenuous influence over their functions.

The deployment of information in the genes, moreover, is itself dependent on the presence of certain RNA and protein molecules in the cell. Since, as described above, the composition of the cell’s interior and the activity of many of its proteins depend on more than just the genes, the portion of the genes’ information content that is actually used by the cell is determined, in part, by non-genetic factors. So, to reiterate, the genes do not uniquely determine what is in the cell, but what is in the cell determines how the genes get used. Only if the pie were to rise up, take hold of the recipe book and rewrite the instructions for its own production, would this popular analogy for the role of genes be pertinent.

As Newman explains, the gene is nothing close to how evolution envisioned it. The gene myth is yet another example of evolution’s failed expectations. It seems that inevitably evolution’s interpretations turn out to be wrong as it has produced a steady stream of false predictions. Evolution is certainly the best counter indicator in the life sciences.

We continue to examine the work of authors George Johnson and Jonathan Losos in their biology textbook, The Living World ((Fifth Edition, McGraw Hill, 2008). In their chapter on evolution and natural selection, these accomplished evolutionists begin by (1) misrepresenting the relationship between microevolution and macroevolution and biological variation here, (2) making a non scientific, metaphysical, truth claim that mandates the truth of evolution here, (3) making the false statement that the fossils themselves are a factual observation that macroevolution has occurred here and here, and (4) making a series of misrepresentations by carefully selecting the evidence to provide to the student and protecting it with circular reasoning here.

Johnson and Losos’ next move is to distort the molecular evidence. They write:

A series of evolutionary changes thus implies a continual accumulation of genetic changes in the DNA. From this you can see that evolutionary theory makes a clear prediction: organisms that are more distantly related should have accumulated a greater number of evolutionary differences than two species that are more closely related.

But how are species judged to be “distantly related”? By what measure are species compared? The answer, of course, is by the similarities and differences in their visible anatomy. So what exactly is this powerful evolutionary prediction? It is that genetic differences between species are proportional to the differences in their visible anatomy. If two species look alike, then their genomes should be similar. If they look very different, then their genomes should be very different. This is by no means a heroic prediction.

There is, however, another problem with this prediction. Aside from not being heroic, it is false. By now the authors have established a trend of misrepresentation and distortion, and predictably the trend continues:

This prediction is now subject to direct test. Recent DNA research, referred to in section 15.3, allows us to directly compare the genomes of different organisms. The result is clear: for a broad array of vertebrates, the more distantly related two organisms are, the greater their genomic difference.

Here the distortion is mainly one of omission. Like saying that geocentrism’s prediction that the planets should travel across the sky is true without mentioning retrograde motion, Johnson and Losos fail to mention important deviations from this pattern that have even evolutionists acknowledging the evolutionary expectation has failed.

Yes, there is a broad pattern of correlation between visible anatomy and molecular sequences, but there are inescapable and significant deviations which are far outside evolution’s “noise” level. If evolution predicts that “organisms that are more distantly related should have accumulated a greater number of evolutionary differences than two species that are more closely related” then evolution is false, end of story.

The authors next discuss the protein evidence, and in like manner continue their distortion:

This same pattern of divergence can be clearly seen at the protein level. Comparing the hemoglobin amino acid sequence of different species with the human sequence in figure 17.7, you can see that species more closely related to humans have fewer differences in the amino acid structure of their hemoglobin. … Again, the prediction of evolutionary theory is strongly confirmed.

Again, this prediction is not only not “strongly confirmed,” it is in fact false. Yes, hemoglobin and many other proteins fall into the non heroic pattern, but other proteins do not. These are well known to scientists, but evolution has unfortunately compromised science.

Johnson and Losos end this misleading section on the molecular evidence for evolution with yet another fallacious icon of evolution, the molecular clock.

In science theory evaluation is a critical skill. It is crucial to take a neutral, unbiased perspective and be willing to acknowledge both pros and cons of even one’s cherished theories. Unfortunately evolutionists don’t follow this scientific dictum. Yes there is plenty of evidence for evolution, but there are problems as well. But one would never know it from reading the evolution genre. Don’t count on evolutionists to give a scientifically accurate evaluation of their theory. Religion drives science, and it matters.

We continue to examine the work of authors George Johnson and Jonathan Losos in their biology textbook, The Living World ((Fifth Edition, McGraw Hill, 2008). In their chapter on evolution and natural selection, these accomplished evolutionists begin by (1) misrepresenting the relationship between microevolution and macroevolution and biological variation here, (2) making a non scientific, metaphysical, truth claim that just happens to mandate the truth of evolution here, and (3) making the grossly false statement that the fossils themselves are a factual observation that macroevolution has occurred here and here.

With this as their start, Johnson and Losos next make a series of misrepresentations of the evidence. First, in an inset story on whale evolution, they show the student a highly selective graphic of the fossil sequence leading to the modern whale. In typical fashion the abundant fossil species that reveal how complicated is the evolutionary hypothesis are omitted. It is as though half a dozen fossils which unambiguously lead to the whale were discovered and nothing else.

Next the authors discuss vertebrate embryos with a graphic showing a reptile, bird and human embryo. They point out that all vertebrate embryos have pharyngeal pouches and a long bony tail. Also, the human embryos "even develops a coat of find fur!" They then inform the student that:

These relict developmental forms strongly suggest that all vertebrates share a basic set of developmental instructions.

But there are significant differences between the embryonic stages of the different vertebrates which the authors fail to mention. If similarities suggest common developmental instructions, then surely the many differences reveal developmental instructions that are not in common. And in any case, why is it that a common set of instructions, to whatever extent they do exist, are evidence for evolution? The authors reveal only selective evidence to the student and make an unjustified claim.

Johnson and Losos next make the circular argument that vertebrates have the same bones:

As vertebrates have evolved, the same bones are sometimes still there but put to different uses, their presence betraying their evolutionary past.

Here Johnson and Losos transition from presenting evidence for evolution to asserting evolution and interpreting the evidence according to the theory. Their phrase "As vertebrates have evolved," marks this unspoken move in the indoctrination. The student is no longer fed evidence for the theory, but instead the truth of the theory has become a given.

Hence the bones in different vertebrates are "the same." After all, they arose from a common ancestor. And since they are "the same," they betray "their evolutionary past." It all makes perfect sense to evolutionists.

And what about those similarities that could not have arisen from a common ancestor? Conveniently, those too are somehow evidence for evolution:

Similarly, in the lower portion of the figure, the marsupial mammals of Australia evolved in isolation from placental mammals, but similar selective pressures have generated very similar kinds of animals.

So similar structures in related vertebrates count as evidence because, after all, they arose from a common ancestor. And similar structures in distant vertebrates count as evidence because, after all, they arose independently from similar selective pressures. Got it (except that selective "pressures" don't generate anything, but don't tell the students that).

Next Johnson and Losos present those structures that have "no use at all!" Back to their whale example, they continue the theme of circular reasoning:

In living whales, which evolved from hoofed mammals, the bones of the pelvis that formerly anchored the two hind limbs are all that remain of the rear legs, unattached to any other bones and serving no apparent purpose.

That, of course, is not an empirical finding but a conclusion based on the assumption that evolution is true. In fact the whale pelvis probably helps in copulation. But so what? After all, whales "evolved from hoofed mammals."

Their next circular example is that vestigial organ, the human appendix. In the great apes it helps with digestion but "The human appendix is a vestigial version of this structure that now serves no function in digestion." So the appendix is evidence for evolution because it is vestigial, and we know it is vestigial because evolutionists say it is.

Unfortunately most students will not be aware of the indoctrination they are receiving. Not will they be aware of the substantial scientific omissions and errors that the text is riddled with. Regarding the appendix, the evolutionary expectation once again failed. As one researcher commented:

Maybe it's time to correct the textbooks. Many biology texts today still refer to the appendix as a 'vestigial organ.'

Indeed, many biology texts do because the science has been compromised by evolution. Religion drives science and it matters.
