Environmental selection is natural selection

Environmental selection during the last ice age on the mother-to-infant transmission of vitamin D and fatty acids through breast milk was published on April 23, 2018 The ectodysplasin A receptor (EDAR) gene has a range of pleiotropic effects, including sweat gland density, incisor shoveling, and mammary gland ductal branching. The frequency of the human-specific EDAR V370A allele appears to be uniquely elevated in North and East Asian and New World populations due to a bout of positive selection likely to…

Vulgar Antagonists vs Quantum Effects

Exosome Cargo Could Be Drug Target For Neuropathic Pain My discussion attempt was removed by Dfm Prime, who claims to be a patient advocate for those who are suffering from neurological insult. See: Works at Neurosensory Neuroregenerative Research Foundation Publication: Catechol-O-Methyl Transferase Inhibition Reduces Symptoms of Hallucinogen Persisting Perception Disorder See for comparison: Oppositional COMT Val158Met effects on resting state functional connectivity in adolescents and adults In my model, fluoroquinolone use to kill gut bacteria sometimes kills the bacteria that…

New Testament Book Cover Refutes Theistic Evolution

Video of Biology of the Book Goats, bookworms, a monk’s kiss: Biologists reveal the hidden history of ancient gospels Collins already had developed a method to identify ancient species by differences in the amino acid sequences of collagen and other proteins preserved in fossils. See: Protein power by Robert F. Service …methods to sequence amino acids lag behind DNA sequencing. The report of 300 million year old proteins is based on ridiculous theories that failed to include what was known about…

Energy-dependent physical and biophysical constraints (5)

Summary: Emmy Noethe’s theorems were developed in the early 1900’s. Richard Feynman inadvertently or purposefully alluded to them as examples of human idiocy. Discover Magazine resurrected the examples of human idiocy in a 2017 article. For comparison, Choi et al., (2017) support the claims that intercellular and interkingdom communication is energy-dependent and controlled by the metabolism of food energy to pheromones. It is obvious that pheromones biophysically constrain the virus-driven degradation of messenger RNA. That fact links everything currently known…

Energy-dependent hydrogen bonds in supercoiled DNA

Chirality Check Most biological macromolecules are homochiral, and enzymes help to maintain this state of affairs; for example, checkpoints ensure that only l-amino acids are incorporated into proteins during translation. The fixation of the only achiral amino acid, glycine in position 6 of the gonadotropin releasing hormone decapeptide protein links the nutrient energy-dependent pheromone-controlled physiology of reproduction from yeasts to humans. That fact about RNA-mediated protein folding chemistry is missing from the chirality check, It also is missing from representations…

Bird-brained theorists

Study: There Are Twice as Many Bird Species as Previously Estimated The issue of biodiversity in all vertebrates was linked from ecological variation to nutrient energy-dependent ecological adaptation by natural selection for codon optimality and differences in morphology paired with differences in behavior in the context of the physiology of reproduction and biophysically constrained cell type differentiation. See: Estrogen receptor α polymorphism in a species with alternative behavioral phenotypes …our results illustrate a detailed chain of events linking a chromosomal…

Energy-dependent de novo creation and neurogenesis

See also: Tasting light links energy from creation to adaptation Developmentally defined forebrain circuits regulate appetitive and aversive olfactory learning reported as: When neurons are ‘born’ impacts olfactory behavior in mice My summary: The de novo creation of different cell types is placed into the context of their energy-dependent birth and the transgenerational epigenetic inheritance of molecular mechanisms that link virus-driven energy theft to all pathology via olfaction, food odors, and human pheromones. See for comparison: Metabolism and neurogenesis …it…

Theories vs facts about polycombic adaptation

See: Demoncrats fight polycombic ecological adaptation Exosomes as miRNA Carriers: Formation–Function–Future Important aspects will be highlighted as a take-home message (THM) at the end of each paragraph. THM: Extracellular vesicles transport miRNA in a paracrine and endocrine manner. Questions regarding the cellular options of producing either microvesicles or exosomes and their difference in miRNA composition and number are still unknown. In my 2014 invited review, the four F’s, Formation–Function–Future and Copulation were included in details about how the nutrient energy-dependent…

Energy-dependent maternal-to-zygotic transition

Small Non-coding RNAs Associated with Viral Infectious Diseases of Veterinary Importance: Potential Clinical Applications ON 11/14/16 The co-author Mohamed Samir wrote:  Because our article is among the top 25% most viewed and downloaded articles in the third quarter of 2016 in “Frontiers in Veterinary Science”, The editor of the journal has invited me to host and moderate a new research topic in his journal about miRNAs in veterinary filed. Thanks God. The topic is virtually guaranteed to bring out the…

Model vs theory: Progress report!

On June 14, 2013, 1) Nutrient-dependent/pheromone-controlled adaptive evolution: a model and 2) Mutation-Driven Evolution were published with divergent/opposite conclusions. 1) …the largest contributor to the development of our personal preferences may be the unconscious epigenetic effects of food odors and pheromones on hormones that organize and activate behavior. If so, the model represented here is consistent with what is known about the epigenetic effects of ecologically important nutrients and pheromones on the adaptively evolved behavior of species from microbes to…
