Understanding species differences

Biology, Brains and Behavior, Genetics

Genes Aren’t Just Architects; They’re Actors by David Dobbs • 

Excerpt: “Robinson and others have for years been waving their hands, pointing at results like this, and arguing that the endgame in genetics is not in differences in what genes we carry, but — especially when most of our genes our shared — in differences in how and when the shared genes express themselves. This is important in understanding differences within a species, whether it be honey bees or humans.”

My comment: In 2000 Elekonich and Robinson extended our 1996 mammalian model of molecular epigenetics and hormone-organized / hormone-activated behavior to insects, with the honeybee as the model organism. I’ve since linked human pheromones to the conserved molecular mechanisms of species from microbes to man in two published papers:

Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behavior (2012)

Nutrient-dependent/pheromone-controlled adaptive evolution: a model (2013)

I’m not sure how anyone else could explore the topic of species differences in more detail than I have provided during that past two decades since my first presentation to a scientific forum (in 1992) and book publication in 1995. I am sure that the differences in the brain and social behavior of insects and humans are nutrient-dependent and pheromone-controlled. There is no other model for that! The fact that the model is fully detailed in the journal ‘Socioaffective Neuroscience & Psychology’ may be the best indicator that David Dobbs is on the same track as I have been since I first began researching human sexuality in the early 1980s.


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.
