More Junk DNA That Isn’t Really Junk After Allproposition.
A study published last week found strong signs of function in mobile repetitive DNA elements. Mobile genetic elements have been heavily recruited by evolutionists in recent years as powerful, undeniable proofs of common ancestry. An underlying assumption in those proofs, aside from the usual non scientific metaphysics, is that such mobile elements insert themselves into the genome at random. But this study suggests they are at least sometimes nonrandom and functional. As one report explains:
“We’ve come to understand that not all repeat sequences are junk DNA,” said Pawel Michalak, an associate professor at the Virginia Bioinformatics Institute. “These repetitive sequences are increasingly being recognized as agents of adaptive change. We discovered a larger than expected amount of genetic variation in these repeating sequences between the fly populations and saw that the variation resulted in potentially functional differences in important biological processes, such as stress resistance and mating.”
The biological roles of these place-jumping, repetitive elements are mysterious.
They are largely viewed as “genomic parasites,” but in this study, researchers found the mobile DNA can provide genetic novelties recruited as certain population-unique, functional enrichments that are nonrandom and purposeful.
“The first shocker was the sheer volume of genetic variation due to the dynamics of mobile elements, including coding and regulatory genomic regions, and the second was amount of population-specific insertions of transposable DNA elements,” Michalak said. “Roughly 50 percent of the insertions were population unique.”
The fact is, as this study further suggests, we don’t really understand genetics well enough to support the kind of hard claims evolutionists make about the evidence.
