Excerpt: “Recognition between parent and offspring is an essential component of reproduction for many species. Its importance is … often facilitated through call recognition by both mothers and offspring…”
My comment: Infant-mother recognition is facilitated across vertebrate species by the epigenetic effects of nutrient chemicals that metabolize to species-specific pheromones. The fact that no one has shown a direct link from auditory stimuli to gene activation in hormone-secreting nerve cells of the vertebrate brain, but the link from pheromones to the medial preoptic area (MPOA) of the avian brain has been detailed, strongly suggests that the auditory stimuli associated with the “call” must first be associated with genetically predisposed “imprinting” that may occur before the eggs hatch, as it appears to do with the eggs of invertebrate species. This “…broadens the time course over which hormonal actions on insect behavior are considered, from egg to adult.” — per the conclusion of Elekonich & Robinson (2000). Their conclusion appears to be based, in part on what we detailed in From fertilization to adult sexual behavior. For example, the molecular epigenetics probably do not change across species. Is any avian species known to be an outlier given the molecular mechanisms of adaptive evolution that ensure nutrient chemical-dependent and pheromone-controlled individual and species survival from egg to adult, which also ensures adaptive evolution in mammals from fertilization to adults?
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.
