Shocking sex secrets


The Shocking Sex Secrets of Insects

NY Times by Marlene Zuk

Excerpt: “Evolution is all about reproduction. What happens at the business end of an animal is essential to whether eggs are fertilized and genes passed on, and nowhere is the variation in sex organs more breathtaking than in insects.”

My comment: The physiology of reproduction is nutrient-dependent and controlled by species-specific pheromones in species from microbes to man. What’s shocking about this report on the sex secrets of insects is a researcher has again failed to recognize that conservation of molecular mechanisms that enable reproduction 13 years after Elekonich and Robinson (2000) extended our 1996 model of hormone-organized and hormone-activated mammalian behavior to insects.  It seems as if many experts have remained oblivious to the biological facts that link what is currently known about the epigenetic effects of olfactory/pheromonal input on adaptations across a continuum of changes in morphology and behavior that define different species.

Since she studies crickets, I wonder if Marlene Zuk has heard about

1) the link between the mandible and genitalia of crickets, which was reported in the context of ecological divergence that precedes sexual divergence, or

2) the link between the diet of grazing nematodes and predatory nematodes with teeth, which is associated with differences in neurogenesis and behavior, or

3) the link between the diet of a human population that supposedly arose during the past ~30,000 in what is now central China and differences in their hair, skin, teeth, and mammary tissue that parallel differences in mice that are due to a single base pair change and single amino acid substitution (see for review Kohl, 2013).

Clearly, if she wants to discuss genitalia, sexual positions, or differences in behavior in the context of evolution, she could begin with nutrient-dependent pheromone-controlled differences in crickets and extend them to humans as we did prior to the review article by Elekonich and Robinson. However, we started with yeasts and link the physiology of their nutrient-dependent pheromone-controlled behavior to other mammals.

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.
