Nutrient dependent pheromone controlled morphogenesis (revisited)

The developmental genetics of space and time: Developmental genes often take inputs from two independent sources

Excerpt:Understanding the concept of morphogen gradients—the mechanism by which a signal from one part of a developing embryo can influence the location and other variables of surrounding cells—is important to developmental biology, gene regulation, evolution, and human health.”

My comment: I am reminded by the content of this articlethat I have not yet published a preprint about nutrient-dependent pheromone-controlled morphogenesis in species from microbes to man. As most of you know, however, nutrient-dependent pheromone-controlled morphogenesis is included in my model of nutrient-dependent pheromone-controlled adaptive evolution.

Although I find no fault with the portrayal of morphogenesis in the fruit fly model, I will note that nutrient-dependent pheromone-controlled morphogenesis is probably best exemplified at the advent of sexual reproduction in yeast. See: Pheromone-Induced Morphogenesis Improves Osmoadaptation Capacity by Activating the HOG MAPK Pathway and see also: Feedback between Population and Evolutionary Dynamics Determines the Fate of Social Microbial Populations. An alternative invertebrate representation can be found in Ecological selection as the cause and sexual differentiation as the consequence of species divergence?

Taken together it has become perfectly clear that natural selection and nutrient-dependent ecological divergence precedes sexual divergence and pheromone-dependent sexual selection in the only model of adaptive evolution that incorporates what is currently known about the conserved molecular mechanisms of epigenetic cause and effect (e.g., among microbes; among populations of flightless crickets confined to the Virgin Islands; and in a human population that arose during ~30,000 years in central China).





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.
