Epigenetics, hormones, pheromones, and bonding

Epigenetics Play Cupid for Prairie Voles By Kate Yandell | June 2, 2013

Females of the pair-bonded rodent species become attached to their lifelong mates following histone modifications near oxytocin and vasopressin receptor genes.

Excerpt:  “…work in other species gave him clues that epigenetics could be important for social behavior. For instance, previous work suggests that modifications are involved in bonds between mothers and offspring in rats.”

My comment: The epigenetic effects on bonding in mammals are nutrient-dependent and pheromone-controlled in my model of Nutrient-dependent / Pheromone-controlled Adaptive Evolution. Cause and effect is exemplified in model organisms in Nutrient-dependent / Pheromone-controlled thermodynamics and thermoregulation. Mutations theory is abandoned to favor Darwin’s ‘conditions of life’ portrayal. Obviously, these nutrient-dependent pheromone-controlled conditions of life precede Natural Selection, which is why mutations theory must be abandoned.

Re: “It’s the first time anyone’s shown any epigenetic basis for partner preference,” said Jeremy Day…

No, it is not the first time anyone’s shown any epigenetic basis for partner preference. In fact, the epigenetic basis for partner preference was reviewed in Gay, Straight, and the Reason Why: The Science of Sexual Orientation, Simon LeVay wrote: “This model is attractive in that it solves the “binding problem” of sexual attraction. By that I mean the problem of why all the different features of men or women (visual appearance and feel of face, body, and genitals; voice quality, smell; personality and behavior, etc.) attract people as a more or less coherent package representing one sex, rather than as an arbitrary collage of male and female characteristics. If all these characteristics come to be attractive because they were experienced in association with a male- or female-specific pheromone, then they will naturally go together even in the absence of complex genetically coded instructions.” (p. 210)

Clearly, the model LeVay comments on is one of epigenetic effects on sexual attraction. We were the first to detail the most important aspects of this “binding problem” in the context of our 1996 Hormones and Behavior review: From Fertilization to Adult Sexual Behavior. See, for example, our section title “Molecular epigenetics.” Also see: Kohl, J.V. (2012) Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors.

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.
