Adaptive evolution is predictable

Predictable Evolution Trumps Randomness of Mutations

Separate bacteria populations may respond to environmental changes in identical ways

Excerpt: “Coyne adds, however, that it may not be practical to extrapolate very much from an asexually reproducing species such as E. coli to organisms that reproduce sexually.”

My comment: Of course it’s practical, and it’s required unless you propose an alternative model using an organism that demonstrates predictable evolution via random mutations. Is Coyne willing to start us off with a demonstration in a model organism that shows sexual reproduction is due to a random mutation? In my model, the advent of sexual reproduction in yeasts is nutrient-dependent and pheromone-controlled.

My comment to the Scientific American site:

I may be the only participant here who has published on nutrient-dependent pheromone-controlled adaptive evolution and modeled it based on what is currently known about molecular epigenetics with the use of animal models of epigenetic effects in species from microbes to man. See, for example, “Nutrient-dependent / Pheromone-controlled Adaptive Evolution.”

There are links from the model to my peer-reviewed publications.

Despite the claims, no scientific evidence suggests that mutations cause adaptive evolution. Adaptive evolution obviously occurs via 4-stages of niche construction: 1) ecological 2) social 3) neurogenic and 4) socio-cognitive. Is is not possible for any mutation to cause fixation/epistasis via step 1 (the ecological niche is nutrient-dependent). Step 2 is required for control of nutrient-dependent adaptive evolution. Ecological niche construction is controlled by the metabolism of nutrients to species-specific pheromones in species from microbes to man. Pheromones establish the constraints of the social niche.

Those who are trapped in the statistics of population genetics where selection somehow occurs for phenotype may need to start with the basic principles of biology and levels of biological organization that link olfaction and odor receptors to the epigenetic tweaking of immense gene networks portrayed in my model of systems biology. But because that’s the only way to understand adaptive evolution it may be worth it to learn. Minimally, you won’t be caught discussing mutation-driven adaptations, or redefining your terms to make it appear that a theory represents the biological facts. It never has, and we can see now that it never will. Adaptive evolution has always been nutrient-dependent and pheromone-controlled, and always will! That’s probably as predictable as anything that’s ever been believed, which makes it somewhat unbelievable that so many people believe in mutations theory.

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.
