Epigenetics: Not in Our Genes

Not in Our Genes

Book review of ” Identically Different” by Tim Spector

Excerpt: “This book concludes with a list of four genetic dogmas that have been overthrown: genes are not our essence; our genetic inheritance can be changed; environmental events can be “remembered” by cells; and what happens in your life can affect later generations. Or, to put it bluntly, almost everything you’ve been told about genetics is wrong.”

My Comments (added to the site, but reproduced below):

In an issue dedicated to THE NEUROSCIENCE AND EVOLUTIONARY ORIGINS OF SEXUAL LEARNING, I published: Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors.

The 10-page article details how the epigenetic influences of nutrient chemicals and pheromones cause adaptive evolution. This occurs via the required ecological, social, and neurogenic niche construction, which is what allows for our hormone-driven brain development and behavior (e.g., our socio-cognitive niche construction). The required pathway also is detailed and includes the required reciprocity at all levels: gene, cell, tissue, organ, organ system.

What’s painfully clear is the fact that endocrine disruptors and other toxins are responsible for disorders of brain development and behavior that are typically absent with proper nutrition and socialization in other species. Why then, does it take evidence from twin studies to make others realize that we are what we eat, and that our pheromones tell others who and what we are?

That’s the common theme across all of molecular biology, and the effects of a toxic environment are evidenced via my use of the honeybee model organism. What the queen bee eats determines her pheromone production and everything else about the interactions of the colony, including the neuroanatomy of the worker bees’ brains.

Does what one twin eats and the exposure to pheromones cause the neuroanatomy of the human brain to change? How could the epigenetic influences of nutrient chemicals and pheromones not be responsible for the differences in twins, and in everyone else? There’s no other model for those differences, and the molecular biology doesn’t change across species from microbes to man.

About James V. Kohl 1307 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.
