Sex differences: demand explanations of the mechanisms

What is the point of spotting sex differences if science cannot explain them?      

Excerpt: “Why don’t we demand explanations of the mechanisms that produce observed sex differences?”

My comment: As we indicated in our 1996 Hormones and Behavior review, sex differences are nutrient-dependent and pheromone-controlled at the advent of sexually differentiated cell types in yeasts.

Conserved molecular mechanisms and the mammalian model of hormone-organized and hormone-activated sex differences in behavior were subsequently extended to invertebrates and to life history transitions in the honeybee model organism.

Using the honeybee model organism as the link from microbes to humans, I reviewed what was known about the biological basis for differences in morphological and behavioral phenotypes in species from microbes to man in Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors

I then provided examples of how nutrient-dependent DNA methylation leads to amino acid substitutions that differentiate cell types in individuals of different species in my most recent published work: Nutrient–dependent / pheromone–controlled adaptive evolution: a model.

All the details of biologically based cause and effect in the context of nutrient-dependent pheromone-controlled cell type differentiation have become clear from the perspectives of physics, chemistry, and conserved molecular mechanisms. However, since evolutionary theorists cannot explain how mutations and natural selection led to the evolution of sex differences, they are motivated to keep serious scientists from explaining the fact that sex differences in cell types and in organisms from species of yeasts to mammals result from ecological variation and nutrient-dependent pheromone-controlled ecological adaptations. There’s a model for that!

Why haven’t you learned more about the model? One reason is that reviewers refused to review the submission of the manuscript I subsequently posted to

This was an invited review: Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems

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.
