Natural variation, neurogenetic networks, and neurogenic niches

Analysis of natural variation reveals neurogenetic networks for Drosophila olfactory behavior OPEN ACCESS ARTICLE (2013) Shilpa Swarup, Wen Huang, Trudy F. C. Mackay, and Robert R. H. Anholt. Proceedings of the National Academy of Sciences.

Excerpt: “Our results suggest that polymorphisms that contribute to natural variation in olfactory perception are not restricted to peripheral chemoreceptors, but may also cause subtle variations in genes affecting neural connectivity and signaling in the olfactory projection.”

My comment: What they help to detail is epigenetic potentiation that makes a trait possible; epigenetic actualization that makes the trait manifest, and epigenetic refinement that makes the trait effective. These three steps are probably required for many new functions of adaptively evolved species.

Two of the three steps link epigenetic control of nutrient-dependent ecological niche construction and subsequent pheromone-controlled social niche construction. This takes us to neurogenetic networks as part of the third step that bring us one step closer to the obvious role of nutrient-dependent pheromone-controlled neurogenic niche construction. From there, it’s just one small step to socio-cognitive niche construction, which is exemplified in species diversity.

The three steps bring proponents of mutations as the cause of adaptive evolution one step closer to the unimagined ridicule they will be subjected to for their belief in such a ridiculous theory despite all the scientific evidence that adaptive evolution is nutrient-dependent and pheromone-controlled in species from microbes to man. The possibility remains, however, that the term mutation may be redefined to include epigenetically-effected chromatin remodeling due to olfactory/pheromonal input, which enables the epigenetic landscape to become the physical landscape of DNA, as is required for adaptively evolved changes in the brain and behavior.

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.
