You Won’t Believe This One: Gene Splicing Stuns and Bewilders Evolutionists

Proteins perform a wide variety of tasks in the cell and when a particular job needs to be done the right protein is quickly synthesized by unwinding the right DNA gene, making a copy, editing the transcript, and translating the transcript, according to the DNA code, into a sequence of amino acids. Evolutionists had no explanation for this incredible and profound molecular manufacturing system (which still out performs anything scientists can come up with), but they remained steadfast. Indeed they argued all of this provided yet more proofs for evolution. Why? Because the DNA code was essentially universal. As one evolutionist explained, while the genetic code is preserved across species, it would not be if the species had been created independently. [1] If that’s true then the genetic code must have somehow evolved. Is that true? It’s difficult to say because that is, as usual, a non scientific claim. But aside from the metaphysics and the unexplained molecular manufacturing system, there is another problem with this story. It has now turned out to demolish evolutionary theory and has left evolutionists staring into the headlights.

Years after the universal DNA code was discovered, several other codes were also discovered which were not only astonishingly complex, but they were not universal. One such code is the so-called splicing code.

In higher organisms many of the genes are broken up into expressed regions, or exons, which are separated by intervening regions, or introns. After the gene is copied the transcript is edited, splicing out the introns and glueing together the exons. Not only is it a fantastically complex process, it also adds tremendous versatility to how genes are used. A given gene may be spliced into alternate sets of exons, resulting in different protein machines. There are three genes, for example, that generate over 3,000 different spliced products to help control the neuron designs of the brain.

And how does the splicing machinery know where to cut and paste? There is an elaborate code that the splicing machinery uses to decide how to do its splicing. This splicing code is extremely complicated, using not only sequence patterns in the DNA transcript, but also the shape of transcript, as well as other factors.

What is also complex about the new code is that it is context-dependent. In fact it even varies in different tissue types within a species. And studies of RNA binding proteins show even more complexity. These proteins are part of the molecular splicing machinery and they often regulate each other leading to an “unprecedented degree of complexity and compensatory relationships.” As one researcher explained:

We identified thousands of binding sites and altered splicing events for these hnRNP proteins and discovered that, surprisingly these proteins bind and regulate each other and a whole network of other RNA binding proteins.

Regulate each other and a whole network of other RNA binding proteins? Needless to say there is no scientific explanation for how this marvel could have evolved. And since this code is not universal but, quite the opposite, highly varying even between tissues, we can safely conclude the “universal code” prediction of evolution is falsified.

If evolution is true then we expect codes to be universal. Here we have an obvious example of a code that most definitely is not universal, so the prediction is false. And if a prediction is false, then either the theory is false, or it must be modified. But with so many falsifications, and so many modifications that make no sense on evolution, it is obvious that something is very wrong with the theory. In this case we would have to say that random mutations just happened to create many different splicing codes, over and over, of unimaginable complexity.
