Controlled adaptations of coexisting ecotypes

Evolution was defined as “changes in gene frequencies in natural populations.” The accumulation of genetic mutations was touted to be enough to change one species to another…. No, it wasn’t dishonesty. I think it was wish fulfillment and social momentum. Assumptions, made but not verified, were taught as fact.

Sinope Diogenes claims (with my emphasis): “There is biologicaly-based and testable evidence that supports the theory that mutations happen. When this evidence is combined with other biologically based evidence about rates of mutation, models can be constructed to test the theory and probability of fixation.”

Clearly, Sinope Diogenes was taught to believe in a ridiculous theory, and I learned about biological facts. See, for example: “…competition for two carbon sources caused initially isogenic populations of the bacterium Escherichia coli to diversify into two coexisting ecotypes representing different physiological adaptations in the central carbohydrate metabolism.”

Those who have continued to tout Richard Lenski’s work as proof of mutations that lead to evolution in E. coli, don’t realize his experiments showed that the molecular mechanisms of nutrient-dependent pheromone-controlled reproduction are conserved in species from microbes to man. The conserved molecular mechanisms link ecological variation to ecological adaptions without the pseudoscientific nonsense of neo-Darwinian theories.

In the “Science” article, the authors claim to “…minimize complications and thus illuminate the fundamental dynamics of adaptation by natural selection in asexual populations.”

Excerpt: “The medium has one limiting resource and supports low population densities (for bacteria) to minimize the potential for crossfeeding on, or inhibition by, secreted byproducts.”

My comment: They eliminated natural selection for nutrients via the medium used to grow the organisms. This limits the metabolism of  nutrients to species-specific secreted byproducts called pheromones that control the physiology of reproduction. Thus, the conserved molecular mechanisms of  nutrient-dependent pheromone-controlled adaptive evolution are eliminated and results are reported in terms of mutations.

This experiment was designed before researchers knew anything about molecular epigenetics. Nothing is illuminated by first eliminating variables that include the epigenetic ‘landscape,’ which becomes the physical landscape of DNA in the organized genomes of species from microbes to man that adapt to their environment.

I am surprised at attempts to explain the evolution of organismal complexity in the context of mutation-driven evolution, when no experimental evidence from model organisms in their natural or typical environments supports that idea. Instead, all experimental evidence supports nutrient-dependent pheromone-controlled adaptive evolution.

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.
