A bacterial world: A series of stages in evolution

We are living in a bacterial world, and it’s impacting us more than previously thought.” February 15th, 2013 by by Lisa Zyga

Excerpt: The percentage of the human genome that arose at a series of stages in evolution.

Excerpt: The olfactory chemicals that attract some animals (including humans) to their prospective mates are also produced by the animals’ resident bacteria.

My comments: The series of stages that involve olfactory chemicals is not random and occurs without mutations.

1. In it’s entirety the article supports non-random adaptive evolution (e.g., sans mutations) via nutrient-dependent pheromone-controlled intracellular signaling and stochastic gene expression as is required for ecological, social, neurogenic, and socio-cognitive niche construction in species from microbes to man.

2. Every section attests to the fact that “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.”

3. In that context, their recognition of Lynn Margulis is also especially pertinent: I wrote: “This indicates that reproduction began with an active nutrient uptake mechanism in heterospecifics and that the mechanism evolved to become symbiogenesis in the conspecifics of asexual organisms (Margulis, 1998)

4. I also wrote: “These epigenetic changes probably occur across the evolutionary continuum that includes both nutrition-dependent reproduction in unicellular organisms and sexual reproduction in mammals.”

5. The difference in my published work is that I detail the mechanisms of nutrient-dependent pheromone-controlled hormone organization and activation of behavior in vertebrates and invertebrates — using the honeybee as the model organism that links microbes to man. I have since modeled the molecular mechanisms of the epigenetically-effected microRNA/messenger RNA balance in greater detail.

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.
