One of the clearest examples of epigenetic effects

11 December 2012 Honey bees’ genetic code unlocked By Mark Kinver Environment reporter, BBC News

Excerpt: “The development of different bees from the same DNA in the larvae is one of the clearest examples of epigenetics in action – mechanisms that go beyond the basic DNA sequence,” said co-author Mark Dickman from the University of Sheffield.

My comment: In my model, the honeybee model organism links the epigenetic effects of nutrient chemical-dependent pheromone-controlled adaptive evolution to genes, behavior, and back in species from microbes to man. Reports like this one of epigenetic effects on proteins called histones within the nuclei of cells add even more intermolecular detail to control of adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction exemplified in the honeybee model.

Human Pheromones: Epigenetic Effects of Odors and Their Affects on Behavior (open access) “Across species comparisons of epigenetic effects on genetically predisposed nutrient-dependent and hormone-driven invertebrate and vertebrate social and sexual behavior indicate that human pheromones also alter the development of the brain and behavior via the same molecular mechanisms. ”

 

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.
