![]() ![]() On the Origin of AARS by Magic-Word SelectionĪnother example comes from the Tokyo Institute of Science. They serve, rather, as statements of faith in the assumed power of natural selection. But it’s pretty clear that she is using magic words as placeholders for scientists’ ignorance. Dance, her article focuses primarily on the science of discovery: how these functions were discovered, and what they might mean for medical treatments to help people. Scarfs arise out of tubes, and cards evolve and develop into the specific cards the magician needs. ![]() ![]() In this magic show, rabbits appear out of hats. “In addition, SerRS acquired a domain unique to this enzyme, which now prevents over-vascularization in developing zebrafish, and likely other vertebrates.”.“ At some point around that same time period half a billion years ago, the TrpRS picked up a WHEP domain….”.“Then, around 540 million to 510 million years ago, an ancestral vertebrate evolved a closed vascular system….”.“Around this same time, TyrRS acquired a glutamic acid–lysine–arginine motif that today is thought to promote angiogenesis.”.“The first blood vascular system, which lacked the endothelium present in modern vertebrates, probably arose in a common ancestor of vertebrates and arthropods around 700 million to 600 million years ago.”.“But in the hundreds of millions of years that they’ve existed, these synthetases (AARSs) have picked up several side jobs.”.“These particular synthetases have been present and available for evolution to modify since protein-based life began.”.“While other proteins have adopted secondary functions…”.“AARSs picked up additional domains that allow them to do much more.”.“For as long as living things have been building proteins based on the code carried by messenger RNA molecules, aminoacyl-tRNA synthetases have been there.” (Where did they come from?).But the article seeks to explain how these additional functions originated, especially in the sidebar, “When these functions arose in evolution”. Some of the additional functions involve angiogenesis, meaning they can be considered as targets for cancer treatments. Dance recounts new findings that show several of these enzymes “moonlight” as workers with other functions.įinding additional functions for these enzymes is a worthwhile discovery. This important family of 20 enzymes stands between the DNA code, written in triplet nucleotide codons, and the protein code, written in amino acids. ![]() In the article, “Protein Synthesis Enzymes Have Evolved Additional Jobs,” writer Amber Dance explains new findings about aminoacyl-tRNA synthetases, abbreviated AARS, the enzymes that attach amino acids to transfer RNAs. Here is an example in The Scientist, a news magazine for working scientists who should know better. New Findings About Aminoacyl-tRNA Synthetases And they get away with it nobody ever blows the whistle on what should be tagged a major scientific foul. Is this not exactly what goes on in evolutionary theorizing? Darwinians have mastered the use of magic words that replace rigor with imagination. Now consider leading journals publishing this account after it has whisked through peer review. They probably arose when the first hood evolved. The steering wheel linked up with the brake pedal to form a universal joint.The crankshaft found a side gig as a steering wheel.Billions of years ago, a chassis appeared.Here is a quick tale about the evolution of the automobile. ![]()
