Research blinds people to effects of a nutrient-poor environment in cave fish

Genetics of how and why fish swim in schools: Research sheds light on complex social behavior

Excerpt: “The motivation to be social is common among fish and humans,” said Greenwood

Excerpt: “That really suggests that there’s some kind of genetic factor controlling this difference,” Greenwood said.”

Excerpt: “…a single gene could cause fish to detect their environment differently…”

Excerpt: “If we can understand the process by which evolution works and the genes that tend to be affected during evolution in these other model systems, we can apply that to humans,” she said.”

My comment: This report from Sept 13, 2013 on research blinds people, which is probably why it was posted to the ISHE’s yahoo group more than five months later, on 2/23/14. It  does not shed any new light on complex social behavior. It merely implies that the environment might cause genetic differences during the evolution of behavior.

If the researchers had reported that the nutrient-dependent de novo creation of species-specific olfactory receptor genes caused the fish to detect their environment differently than might be expected to occur in blind cave fish, that fact might have helped others understand the process by which ecological variation involves genes that tend to be epigenetically effected during ecological adaptations that occur in other model organisms.

For example, that fact could have been compared to facts about blind cave fish. They do not need eyes in their nutrient-poor environment, and the physiology of reproduction controls eye regression via the ecological adaptations to a nutrient-poor environment that are manifested in morphological and behavioral phenotypes. This exemplifies biologically-based cause and effect that is common among 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.
