Epigenetics and evolutionary success

Nature News article: Epigenetics posited as important for evolutionary success

Excerpt: “Although biomedical researchers have been investigating the links between epigenetics and human health for some time, evolutionary biologists are just beginning to take up the subject. Richards, who helped to organize a special symposium on ecological epigenetics at a meeting of the Society for Integrative and Comparative Biology (SICB) in San Francisco this month, says that the field has the potential to revolutionize the study of evolutionary biology.”

Symposium: Ecological Epigenetics

Excerpt: Epigenetics mechanisms – by which environmental signals mediate differences in gene expression – have the power to describe the emergence and selection of phenotypic variation on ecological timescales, and the reciprocal contribution of such variation to ecological processes. Because the conceptual and technical advances necessary to characterize epigenetic variation and processes in nature have just begun to emerge, now is a particularly opportune time to develop a framework that will guide and facilitate exceptional studies in Ecological Epigenetics.

My comment: The above translates well to what I conceptualized as nutrient chemical-dependent and pheromone-controlled epigenetic tweaking of the immense gene networks required for adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction. Arguably, this model appears to go beyond the data and theory presented during the symposium (linked above): Human Pheromones: Epigenetic Effects of Odors and Their Affects on Behavior.  So does my published work from last year Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors.

Nevertheless, others seem destined to soon grasp the entirety of the genes-to-behavior and back approach exemplified in the honeybee model organism that links olfaction and odor receptors to a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.

 

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.
