Bio-CHEMICAL complexity

See: “Human brains share consistent genetic blueprint and possess enormous biochemical complexity.” September 19th, 2012.

Excerpt: “Despite controlling a diversity of functions, ranging from visual perception to planning and problem-solving, the cortex is highly homogeneous relative to other brain regions. This suggests that the same basic functional elements are used throughout the cortex and that understanding how one area works in detail will uncover fundamentals that apply to the other areas, as well.”

My comment: It seems pertinent to offer this summary so that human ethologists, evolutionary psychologists, cognitive neuroscientists, and theorists from other disciplines might better understand the fact that no domain-specific modules exist, and that the concept of domain-specific mental modules lies outside the context of what is already known about adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction.

There is nothing about the enormous biochemical complexity of the human brain that suggests its complexity could be reduced to a ridiculous theory in which domain specificity was adaptive in any species from microbe to man. For contrast, nutrient chemical-dependent and pheromone-dependent adaptive evolution ensure that the human brain evolved in accord with the epigenetic tweaking of immense gene networks in superorganisms that solve problems through the exchange and the selective cancellation and modification of signals.

These superorganisms can be microbes, invertebrates, or vertebrates as it is now clearer how an environmental drive evolved from that of food ingestion in unicellular organisms to that of socialization in insects with no random mutations required to link sensory cause directly to the intracellular signaling and stochastic gene expression that is required in species from microbes to man.

About James V. Kohl 1307 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.
