A recent journal study purported to have demonstrated “evolution in action”. The authors claimed to have discovered the evolution of a new sex chromosome in members of the fish genus Xiphophorus. This claim is supposed to provide clues about the origin of sex chromosomes, as well as explain why so many fish have reproductive systems that do not always follow the standard vertebrate gender systems.
This discovery was part of a long-running experiment with swordtails and platys, commonly kept livebearing aquarium fish. They are commonly used as lab animals, particularly in the study of skin cancers. However, this study was not looking at cancers. Instead, for thirty years, researchers have been hybridizing platies and swordtails together and examining the genetics of some of the offspring. This project covered over 100 generations of swordtails and platys. As of December 2018, they announced the discovery of a new sex chromosome.
However, as is often the case with evolutionary papers, all that glistens is not gold. In fact, in this case, nothing that glistens is gold. What happened was during the process development in the hybrid baby fish, the sex-determining portion of one of the X chromosomes migrated over to one of the chromosomes that usually does not determine the sex of the fish. “”We found out that introgression — the movement of genetic material from one species to another — and the selection of pigmentation phenotypes results in the retention of an unexpectedly large maternally derived genomic region.” The head researcher on the project was quoted as saying. Essentially, part of the mothers X chromosome moved over into a different area of the genome.
This new sex chromosome the evolutionists are trumpeting as being a piece of the evolutionary puzzle is, in fact, nothing of the sort. Instead, what has happened here is an error in the correct formulation of the embryo. Normal embryos would have an X and potentially either an X or a Y chromosome. Those chromosomes would determine the gender of the embryo. In this instance, one of the X chromosomes was damaged in development. Instead of forming naturally, in effect it donated part of itself to a chromosome that normally has nothing to do with sex determination.
This is not a new sex chromosome. In fact, there is no new information at all present in this genome. All the information available was present in both parents and passed to the offspring. The information simply got rearranged. Nothing is new here. Calling this a new sex chromosome is simply and totally absurd. The fish still have two sex chromosomes. The information has simply been rearranged. There is no new information. Further, creating this new sex chromosome required the existence of a sex chromosome. In other words, the only way to generate a sex chromosome is with a preexisting sex chromosome. This proves that the chromosomes which were generated do nothing to help the evolutionary paradigm.
Unfortunately, articles like this are all too common in the evolutionary literature as the ruling class attempts to control the narrative. The scientists make a discovery of some nature and either deliberately distort it in their own papers, or when it is written up for the scientific layman, the science writers distort it to support the evolutionary paradigm. Unfortunately, this is the issue with having a ruling paradigm. It will frequently suppress information, or distort it in order to support what the paradigm leaders want to portray.
From a creation science perspective, this newly formed sex chromosome is nothing special. Instead, it is simply a product of the fall and the curse of sin that entered the world through the actions of Adam. When Adam sinned, the living world began to slowly break down and die. This includes the genomes. This new chromosome is actually a genetic malfunction. It is a broken reminder of the curse on all of the world, not just the human race. The running down of the genome affects all life, from the smallest microbes to the largest dinosaurs. Attempting to use the running down of the genome as evidence for evolution is both specious and ridiculous, even more than the laughable panspermia idea postulated by some evolutionists to get around the impossibility of life’s origin on earth.
