Symbiotic bacteria and pheromones

Microbial Mediators

Researchers show that symbiotic bacteria can help hyenas communicate with one another.

Excerpt: “Only now are we discovering the role of what we think of as inconsequential passengers—the bacteria—and how important they are.”

My comment: The microbial metabolism of nutrients in bodily secretions that results in sex differences in species-specific social odors called pheromones, which correlate with reproductive state, has been detailed in publications that predate “A Fear of Pheromones” by Lewis Thomas  (1971). The idea that more than 40 years later “Only now are we discovering the role of symbiotic bacteria…” exemplifies how that fear has retarded scientific progress across disciplines.

Progress has been retarded despite what is known about the conserved molecular mechanisms of nutrient-dependent pheromone-controlled alternative splicings that link the epigenetic ‘landscape’ to the physical landscape of DNA in the organized genomes of species from microbes to man. See also: Nutrient–dependent / pheromone–controlled adaptive evolution: a model for examples of what the microbiome contributes to the divergence of species (e.g., everything).

What did you think caused species diversity? Is there a model for that?

Kudos to Kevin Theis and his colleagues for making more progress towards extending molecular epigenetics across species than might otherwise have been considered possible by theoretical biologists, evolutionary psychologists, and human ethologists who have not yet learned that Bird odour predicts reproductive success just as Scent marking increases male reproductive success in wild house mice, and that pheromones control the physiology of nutrient-dependent reproduction across species. If understanding the biology of adaptive behaviors requires pattern recognition, there are clearly too many researchers who do not recognize this pattern in vertebrates or how the pattern originated in microbes and was conserved across many vertebrate species via the insertion of achiral glycine in the molecule of gonadatropin releasing hormone.

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.
