They are what they eat, and so are we

To Boldly Go Where No Bee Has Gone

Excerpt: “A new study examines scouts’ brains and finds that novelty-seeking in humans and bees seems to be based on some of the same genes.

My comment: It’s becoming more difficult for me to keep up with advances like this because they are coming so rapidly. Earlier today, for example, I noticed an article indicating conservation of gonadotropin releasing hormone across insects, which helps to establish an evolutionary continuum from microbes to man. But this article on bees is central to the continuum, so I attempted to add my comments (pending approval) to the Science Magazine site. Typically, I would wait to read these articles in their entirety, but I have no time to do this right now.

What the queen eats metabolizes to pheromones that determine everything involved in the behavior of the colony, including the neuroanatomy of worker bee brains. Does this new evidence suggest that what the scouts eat determines neurotransmission and receptor content in brain tissue? If so, this might best exemplify nutrient-dependent calibration of individual survival, and pheromone-driven standardization and control of speciation from microbes to man. In mammals, for example, we see nutrient-dependent luteinizing hormone (LH) – driven steroidogenesis linked to species specific pheromone production. And the pheromones control gonadotropin releasing hormone secretion and steroidogenesis in well-nourished conspecifics. This reciprocity is responsible for properly timed reproductive sexual behavior that depends on proper food choice and mate choice. Epigenetic effects of nutrient chemicals and pheromones that can be measured in assays of LH in mammals attest to the common molecular biology of species from insects to mammals, but also from microbes to man because a form of GnRH is the alpha mating pheromone of brewer’s yeast. The honeybee already serves as a model organism for studying human immunity, disease resistance, allergic reaction, circadian rhythms, antibiotic resistance, the development of the brain and behavior, mental health, longevity, diseases of the X chromosome, learning and memory, as well as conditioned responses to sensory stimuli (e.g., food odors and social odors). Shall we use the honeybee as a model for the epigenetic effects of olfactory/pheromonal input across species from microbes to man?

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.
