Nonsensical comparisons: deer, dog, human

Excerpt: “A deer’s sense of smell, like a dog’s, can be anywhere from five hundred to a thousand times more acute than a human’s.”

My comment: These are the commonly touted nonsensical comparisons that prevent people from realizing the importance of their sense of smell. The researchers would rather have you continue to believe that the sense of smell in other animals is superior to the human sense of smell when no experimental evidence suggests that is true. Like deer, dogs, and every other animal species on the planet, we can detect differences in the fatty acid content of food and differences in social odors, called pheromones, that vary with sickness.

Excerpt from a requested literature review, which I submitted 3/14/14:

“…if not for the human ability to detect fatty acid content in foods [1] and the human ability to detect social odors linked to sickness [2], this review might end here.”

The review links the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from microbes to man via the ability to detect olfactory/pheromonal input. That ability is conserved across all species because the molecular mechanisms of nutrient-dependent pheromone-controlled ecological adaptations are conserved across all species.

Across-species comparisons made by observing differences in behavior were addressed by Dobzhansky [3]. “”The notion has gained some currency that the only worthwhile biology is molecular biology. All else is “bird watching” or “butterfly collecting.” Bird watching and butterfly collecting are occupations manifestly unworthy of serious scientists! ( p. 443)”

Fifty years later, we still have bird watchers and butterfly collectors telling us about differences in deer, dogs and humans. And the bird watchers and butterfly collectors presenting their nonsense at the meeting of the American Chemical Society have still learned nothing about molecular biology or conserved molecular mechanisms in species from microbes to man.

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.
