Food preferences and mate preferences

Please note the distinct difference in the interpretation of results from the same study. Nature posits that bacteria are sniffing out their food, while The Scientist posits bacteria are sniffing out each other.

Bacteria sniff each other out. When sensing the presence of other species, bacteria meet the textbook definition for olfaction.  Nijland, R. & Burgess, J. G. “Bacterial olfaction,” Biotechnology Journal, 2010.

There is only one animal model for food choice and for mate choice. Since the animal model is so clearly based on olfaction–even in bacteria–can anyone detail how other animals came to rely on visual perception of attractive physical features for mate choice? The all-too-common visual approach to human physical attraction is akin to the visual perception of attractive foods being causal to the development of food preferences.  I discussed this in my July 2, 2010 presentation to the American Mensa Society, as seen in these two 5-minute excerpts from the presentation:

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.
