Excerpt: “Who would have thought, just a few years ago, that we would be able to study sexual conflict at the molecular level… or that microbes would become wonderful experimental models for studying the evolution of social behaviour…”

My comment: We incorporated the study of sexual conflict at the molecular level when we began to detail a model for the adaptive evolution of sexual behavior  in our 1996 review article: From Fertilization to Adult Sexual Behavior. We wrote: “…if specific genes or genomic regions are found to be primary determinants of sexual orientations, upstream and downstream genes are likely also to play crucial roles. And these multigene interrelationships will have profound impact upon phenotypes and judgments derived therefrom.” (We included a section on molecular epigenetics and elaborated on this fact: “Yet another kind of epigenetic imprinting occurs in species as diverse as yeast, Drosophila, mice, and humans.”)

The next sentence from the same paragraph quoted above addresses the fact that microbes are “wonderful experimental models for studying the evolution of social behaviour…” We wrote “Parenthetically it is interesting to note even the yeast Saccharomyces cerevisiae has a gene-based equivalent of sexual orientation (i.e., a-factor and alpha-factor physiologies). These differences arise from different epigenetic modifications of an otherwise identical MAT locus (Runge and Zakian, 1996; Wu and Haber, 1995).”

The development of this model incorporated what is neuroscientifically known and resulted in 2012 publication of  Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors. The concluding sentence is: “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.”

The answer to the questions about who would have thought about sexual conflict at the molecular level, or that microbes could be used to model social behavior is clear. My coauthors and me in 1996,  and in 2001. It was me again in a 2007 book chapter, and in a 2012 review. It’s me again in Nutrient–dependent / Pheromone–controlled Adaptive Evolution: A Model (published June 14, 2013).

Now, the questions are: 1) Who thinks that evolutionary theory did not long ago move from story-tellling to accurate representations of established facts?  2) How much longer will it be until evolutionary theorists grasp the fact that adaptive evolution is nutrient-dependent and pheromone-controlled in species from microbes to man?

At least a decade ago, it should have been clear that “Behavioural ecology” incorporates what I began to detail about ecological, social, neurogenic, and socio-cognitive niche construction in my first presentation to a scientific forum in 1992, and then with co-author Robert Francoeur  in a 1995 book (paperback 2002) before publishing in the research journals. Who can we thank for muddying up that clarity with their ridiculous opinions and commentaries? Who still knows nothing about the basic principles of biology and levels of biological organization required to link sensory input to behavior in species from microbes to man? When will everyone understand the importance of Behavioural Ecology?

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.
