Brain structure and function sans mutations

In the Human Brain, Size Really Isn’t Everything

By CARL ZIMMER Published: December 26, 2013

Excerpt: The emergence of the human mind might not have been a result of a vast number of mutations that altered the fine structure of the brain. Instead, a simple increase in the growth of neurons could have untethered them from their evolutionary anchors, creating the opportunity for the human mind to emerge.

My comment: Of course the human mind did not result from a vast number of mutations. This is simply a casual admission that Carl Zimmer has been wrong about everything he has ever reported in the context of mutation-driven evolution.  Why doesn’t he simply say that the human brain exemplifies how ecological variation results in nutrient-dependent pheromone-controlled adaptations? No experimental evidence ever suggested that our brain was the result of mutation-initiated natural selection.

The evolution of distributed association networks in the human brain

Excerpt 1: “Critical to function, the human brain has accumulated cell types that suggest mechanisms to integrate information over large territories of cortical input – adaptations that may have allowed our ancestors to benefit from the expansion of distributed association zones.”

Excerpt 2: “Mesulam came to a similar conclusion: ‘Neural pathways arising from sensory receptors and leading toward motor nuclei display hierarchical polarity. In contrast, the flow of information used for intermediary processing displays patterns consistent with parallel and re-entrant processing’ [41]. This form of circuit, which may be expanded in hominin evolution, is suited to functions related to top-down control and internal mentation.”

The brain structure and function of our ancestors, and every other species on this planet with a brain arose via ecological variation that enabled increasing organismal complexity via the nutrient-dependent differentiation of cell types. Nutrient-uptake alters the seemingly futile thermodynamic cycles of protein biosynthesis and degradation that results in alternative splicings of pre-mRNA and the amino acid substitutions that differentiate all cell types in all individuals of all species. The differentiation of these cell types is controlled from the top down via the metabolism of nutrients to species-specific pheromones that control the physiology of reproduction.

How could anyone ever come to the conclusion that the complexity of our brain structure and function mutated into existence? There is a clear trail of nutrient-dependent pheromone-controlled adaptations that links ecological, social, neurogenic, and socio-cognitive niche construction via the epigenetic effects of olfactory/pheromonal input on the de novo creation of olfactory receptor genes to the development of our brain and species-specific behaviors.

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.
