Epigenetic 'memory' key to nature versus nurture

Researchers have made a discovery that explains how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature. The discovery explains the mechanism of this memory — a sort of biological switch — and how it can also be inherited by offspring. – ScienceDaily (2011-07-25)

Click on the link to this article and you should see pictures of bees on flowers. Although there is no mention of their significance, which may be unknown to the journalist, the pictures link honeybees to flowers, food odors, and social odors (called pheromones)  in a manner that is now becoming understood. Simply put, the molecular biology of chemical communication is the same across all species from plants to animals. Their genetic “nature” is influenced by stimuli from the environment. Chemical stimuli are more important than any other form of sensory stimuli in this regard. Whether the chemicals are associated with pollen and the bee-assisted reproduction of flowers; the human cultivation of plants with enticing food odors, or the pheromones associated with reproduction in all animal species, the epigenetic influence of these chemicals is obviously the most important of all to species survival.

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.
