Plasticity: Mimicry based on Darwin’s conditions of life (2)

Biologists zero in on role of plasticity in evolution

Excerpt: “…were able to show that a single molecular pathway plays a role in both heritable changes in the flies’ number of ovarioles—egg-producing compartments in the ovaries—and in how they react to their environments by shutting down some ovarioles.”

Abstract excerpt: “This demonstrates that a plastic response conserved across animals can underlie the evolution of morphological diversity, underscoring the potential pervasiveness of plasticity as an evolutionary mechanism.”

My comment: This experimental evidence supports the claim that nutrient availability is the ecological variable that controls ecological adaptations via the metabolism of nutrients to species-specific pheromones. Effects of food “odors” and pheromones clearly link the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from microbes to man via conserved molecular mechanisms. No unknown evolutionary mechanisms appear to be involved.

These biologists have zeroed in on the the role of plasticity in ecological adaptations.  Their experimental evidence takes us even further away from ideas about evolution that only make sense to population geneticists and their minions. Their ideas about evolution have never made sense in the light of biology.  That’s why experimental evidence continues to show that nothing about evolution makes sense in the light of molecular biology. In the light of molecular biology, ecological variation and conserved molecular mechanisms enable ecological adaptations.

In the light of molecular biology, nutrient-dependent pheromone-controlled ecological adaptations are manifested in morphological and behavioral phenotypes of species from microbes to man.

The species have not evolved. They have ecologically adapted. Species diversity exemplifies the plasticity that enables ecological adaptations. Species diversity does not exemplify evolution because the divergence of reproductive traits is nutrient-dependent and pheromone-controlled in all species. Natural selection has always been for nutrients and the metabolism of nutrients to species-specific pheromones has always enabled sexual selection in the context of the nutrient-dependent pheromone-controlled physiology of reproduction.

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.
