Teeth evolved: a short misrepresentation

Teeth: a Very Short Introduction

Description: Presents the story of teeth – from the earliest tooth-bearing fishes hundreds of millions of years ago through amphibians, reptiles and, ultimately, mammals

Teeth are amazing – the product of half a billion years of evolution.

My comment: Teeth are phenotypic manifestations of how ecological variation is linked from the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from nematodes to mammals. No matter how many times I attest to the fact that teeth obviously arose in the context of RNA-directed nutrient-dependent DNA methylation and the metabolism of nutrients to species-specific pheromones that control the physiology of reproduction in species from microbes to man, Jay R. Feierman will post information like this to the ISHE human ethology yahoo group to keep members focused on the pseudoscientific nonsense of neo-Darwinism.

See, instead: System-wide Rewiring Underlies Behavioral Differences in Predatory and Bacterial-Feeding Nematodes reported as: The neurobiological consequence of predating or grazing “”The patterns of synaptic connections perfectly mirror the fundamental differences in the feeding behaviours of P. pacificus and C. elegans”, Ralf Sommer concludes. A clear-cut result like that was not what he had necessarily expected.””

If it took millions of years for P. pacificus to evolve the first tooth, the species would have gone extinct. Instead, what happened was this: RNA-directed DNA methylation led from a difference in nutrient uptake to an ecological adaptation in mouth parts, such as teeth, which is a common occurrence in cricket species and humans.  The concurrent system-wide rewiring led to an adaptation of behavior.

Serious scientists realize that DNA methylation leads to amino acid substitutions and cell type differentiation via nutrient-dependent pheromone-controlled reproduction in species from nematodes to humans. Only people like Feierman continue attempts to mislead others.

 

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.
