Sex pheromones do not evolve through genetic mutation

The Curious Case of the Lusty Wasps by Lizzie Wade on 13 February 2013, 1:40 PM

Excerpt: “…new sex pheromones may evolve through genetic mutation before potential mates develop the ability to detect them.”

My comment: Sex pheromones don’t evolve through genetic mutations. They are nutrient-dependent, not mutation-dependent. Nutrient-dependent pheromone-controlled adaptive evolution is made possible by the epigenetic effects of nutrients on intracellular signaling, the microRNA/messenger RNA balance, alternative splicing, and activity-dependent stochastic gene expression, which is controlled by the metabolism of nutrients to species-specific pheromones.

The epigenetic effects of nutrients establish the ecological niche; pheromones establish the social niche. Feedback loops that link ecological and social niche construction to neurogenic and socio-cognitive niche construction are exemplified in the honeybee model organism, which links adaptive evolution in species from microbes to man via the same molecular mechanisms.

Mutations theory links nothing given the requirement to get from genes to behavior and back, which is the requirement for adaptive evolution. For contrast, “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.” — Kohl, J.V. (2012) Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors. Socioaffective Neuroscience & Psychology, 2: 17338.

 

About James V. Kohl 1307 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.
