Nutrient-dependent origin of the genetic code

RNA editing and modifications of RNAs might have favoured the evolution of the triplet genetic code from an ennuplet code

Article excerpt: “The fact that today the anticodons are modified, and in particular modified by means of amino acids in a statistically significant way (Di Giulio, 1998), would make to presume in: (i) an intimate evolutionary relationship between amino acids and anticodons for the origin of the genetic code…”

My comment: That suggests the origin of the genetic code can be found in the context of ecological variation and nutrient-dependent amino acid substitutions that  differentiate cell types in individuals of all species in which the physiology of reproduction is controlled by the metabolism of nutrients to pheromones.

Keep in mind the unenviable position of Jay R. Feierman, who is moderator of the International Society for Human Ethology’s yahoo discussion group. Like Jon Lieff, Feierman is a psychiatrist. Unlike Jon Lieff, Feierman knows nothing about the basic principles of biology and levels of biological organization required to link the epigenetic landscape to the physical landscape of DNA in the organized genome of species from microbes to man. However, Feierman makes claims like this in reference to my published works:

Jay R. Feierman: Variation is not nutrient availability and the something that is doing the selecting is not the individual organism. A feature of an educated person is to realize what they do not know. Sadly, you don’t know that you have an incorrect understanding Darwinian biological evolution. 

My comment: Feierman’s understanding of Darwinian biological evolution is what leads him to tout this ridiculous claim:

Jay R. Feierman: I am absolutely certain that if you showed this statement to any professor of biology or genetics in any accredited university anywhere in the world that 100% of them would say that “Random mutations are the substrate upon which directional natural selection acts” is a correct and true statement.

Serious scientists continue to see experimental evidence that attests to the fact that Feierman and those who still share his ridiculous ideas about biologically based cause and effect are among the uneducated “know it alls” who think their academic credentials make up for their ignorance. They are also among the academically irresponsible educators who are teaching nonsensical theories to students who may never learn about how ecological variation leads to ecological adaptations and biodiversity because they’ve been taught to believe in “Evolution for Dummies.”

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
