Ants Can Change Their Roles, Study Finds
Excerpt:
The researchers found that certain compounds could modify proteins called histones, which affect how tightly DNA is coiled and whether certain other proteins are able to gain access to it.
My comment: The molecular mechanisms of nutrient-dependent pheromone-controlled RNA-mediated amino acid substitutions in histones that stabilize supercoiled DNA in the organized genomes of all invertebrates and invertebrates are conserved across all living genera. If they were not, organisms could not behave appropriately in during their ever-changing ecological niche construction and social niche construction.
In another ant species, the molecular mechanisms link UV light to c in the context of foraging behavior. In bacterial the conserved molecular mechanisms link UV light from hydrogen-atom transfer in DNA base pairs to the NORAD system of cellular protection against virus-induced genomic entropy.
Dobzhansky (1973) put all this into perspective when he noted in Nothing in Biology Makes Any Sense Except in the Light of Evolution that
“…the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla (p. 127).”
The light of evolution is sunlight (see Schrodinger, 1944). But people did not understand Dobzhansky’s sense of humor. Like Schrodinger, Dobzhansky linked ecological variation to ecological adaptation. The links were established at a time when serious scientists were not allowed to openly challenge the dogma of the neo-Darwinists. The serious consequences of challenging unarmed peers to a battle of wits were typically avoided. So, Dobzhansky framed his claim in the context of a joke about the difference between the definition of mutation and the facts about amino acid substitutions.
The neo-Darwinists thought he meant that the mutations, which cause all pathology were like virucidal light. In moderation, UV light enables the energy-dependent links from hydrogen-atom transfer in DNA base pairs to unperturbed RNA-mediated amino acid substitutions and protein folding chemistry during theromodynamic cycles of protein biosynthesis and degradation. Outside the context of the fine-tuned balance of these thermodynamic cycles, organisms that cannot find enough food or that eat too much, are like those that are exposed to too much sunlight. They do not mutate and evolve. They die from starvation or social stress. That was the joke. The neo-Darwinists still don’t get it.
When Dobzhansky made the claim about the single amino acid substitution that differentiates three primate species, he knew that protein folding was nutrient-dependent and that the physiology of reproduction was controlled by pheromones in species from microbes to primates. He established the claim about the amino acid substitution in this context (with my emphasis):
Cytochrome C is an enzyme that plays an important role in the metabolism of aerobic cells. It is found in the most diverse organisms, from man to molds. E. Margoliash, W. M. Fitch, and others have compared the amino acid sequences in cytochrome C in different branches of the living world. Most significant similarities as well as differences have been brought to light. The cytochrome C of different orders of mammals and birds differ in 2 to 17 amino acids, classes of vertebrates in 7 to 38, and vertebrates and insects in 23 to 41; and animals differ from yeasts and molds in 56 to 72 amino acids. Fitch and Margoliash prefer to express their findings in what are called “minimal mutational distances.” It has been mentioned above that different amino acids are coded by different triplets of nucleotides in DNA of the genes; this code is now known.
Dobzhansky obviously did not want to offend anyone who preferred to express their findings in the context of de Vries definition of mutation and their ridiculous assumptions about how long it might take for one species to evolve into another. No matter how politely you try to tell someone whose research is reported in terms of mutations and evolution that they are unenlightened, when they realize you are telling them that they did not consider the role of nutrients in their explanation, they will hate you for exposing their ignorance.
Some things about academia never change until after the paradigm shift has come and gone.
For example, see: Origins of De Novo Genes in Human and Chimpanzee
Conclusion: Our results indicate that the expression of new loci in the genome takes place at a very high rate and is probably mediated by random mutations that generate new active promoters. These newly expressed transcripts would form the substrate for the evolution of new genes with novel functions.
For comparison, Dobzhansky (1973) wrote:
I am a creationist and an evolutionist. Evolution is God’s, or Nature’s, method of Creation.
My comment: God’s method of Creation appears to link sunlight to biophysically constrained nutrient-dependent RNA-mediated protein folding chemistry via amino acid substitutions that differentiate all cell types in all individuals of all living genera.
Caveat: Dobzhanzky (1973) added:
Creation is not an event that happened in 4004 B.C.; it is a process that began some 10 billion years ago and is still under way.
My comment: Of course he knew that would placate the neo-Darwinists who believed the fossil record provided evidence of mutation-driven evolution via natural selection. The theorists have remained unenlightened, and Dobzhansky must have known that they will always remain unenlightened.
So, like all other serious scientists today, he threw insults at the unenlightened that they still do not understand. They are too unenlightened. They didn’t even get his joke about mutations in the LIGHT of ecological adaptations. Mutations prevent the adaptations, which supports one of Dobzhansky’s earlier claims:

My comment: The flow of carbon through ecosystems is nutrient-dependent and controlled by the physiology of reproduction. Evolution controls nothing. Darwin’s “conditions of life” control everything. Neo-Darwinian evolution is based on pseudoscientific nonsense.
