Start signal for RNA-mediated events

Start signal for transcription of stressed genes identified

Excerpt 1): “…stress is “a psychological and physical reaction to external stimuli…”

My comment: Identification of the start signal associated with stress does not link it to mutations and natural selection in the context of the evolution of biodiversity. Instead, identification of the start signal links it from ecological variation to ecological adaptations via conserved molecular mechanisms in species from microbes to man.

“The newer and often redefined terms for pheromones limit the use of what is now known about their epigenetic effects, which are also associated with social stress on adaptively evolved socio-cognitive niche construction (Flinn, Nepomnaschy, Muehlenbein, & Ponzi, 2011; O’Connell & Hofmann, 2011, 2012; Whiten & Erdal, 2012). For example, social stress (see for review McEwen, 2012, 2013) associated with the absence of pheromones (Niwa et al., 2013) or with their presence and aggression (Barik et al., 2013) is as likely as nutrient-dependent stress associated with food acquisition to alter hormones and behavior during development. That is because the epigenetic effects of nutrient stress associated with food odors and the epigenetic effects of social stress associated with pheromones occur via the GnRH-controlled pathway, which includes both HPG axis and HPA axis regulation.” Kohl (2013)

About James V. Kohl 1308 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.
