Light ‘drives’ adaptation; nothing ‘drives’ evolution (3)

See also Light ‘drives’ adaptation; nothing ‘drives’ evolution (2) 100 feet below the surface bioluminescent organisms are the dominant light source, study shows Excerpt: “Luminescent marine organisms each have a unique light signature. By looking at the time series light generated by a flash within the instrument, we were able to determine who was there making the flash,” Cohen explained. “It’s a useful tool, particularly at this time of year when relatively few species are present.” Bioluminescence is known to…

Consciousness is simply food rearranged

The claim that consciousness is simply food rearranged can be placed into a historical perspective that crosses more than 70 years. Historical perspective: (1944) What Is Life? Excerpt: Indeed, in the case of higher animals we know the kind of orderliness they feed upon well enough, viz. the extremely well-ordered state of matter in more or less complicated organic compounds, which serve them as foodstuffs. After utilizing it they return it in a very much degraded form -not entirely degraded,…

Non-random pheromone-controlled cell type differentiation

Experience-Dependent Plasticity Drives Individual Differences in Pheromone-Sensing Neurons Aug 17, 2016   •Individual differences in cell types are not random •Sex differences in pheromone-sensing neurons are controlled by experience •Changes in specific cell types are governed via “use it and lose it” plasticity •Targeting plasticity to specific cell types changes animal behavior This was reported as: Long-term exposure to female scents changes courtship behavior in male mice The senior author co-authored Chromatin remodeling inactivates activity genes and regulates neural coding…

Energy-dependent RNA methylation (6)

After I published Nutrient-dependent/pheromone-controlled adaptive evolution: a model, Lynnette Ferguson and Justin O’Sullivan invited me to submit this review of nutritional epigenetics for inclusion in a special issue of the journal “Nutrients.” Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems (April 10, 2014) Abstract: This atoms to ecosystems model of ecological adaptations links nutrient-dependent epigenetic effects on base pairs and amino acid substitutions to pheromone-controlled changes in the microRNA / messenger RNA balance and chromosomal rearrangements. The nutrient-dependent pheromone-controlled changes…

Epigenetic (re)programming of behavior (3)

Bipolar drug turns foraging ants into scouts Excerpt: “DNA methylation has become nearly synonymous with epigenetics,” says Brendan Hunt, an insect geneticist at the University of Georgia in Griffin. “This research brings needed attention to the importance of other epigenetics marks, like histone modifications.” “We finally have a mechanism to understand ‘nurture’ in molecular terms,” says Gene Robinson, a geneticist at the University of Illinois, Urbana-Champaign, who studies caste determination in honey bees. The ant study, he adds, highlights “how…

Hematopoiesis and practopoiesis

Practopoiesis A thought results primarily from an adjustment of the brain hardware, and not from a computation executed by that hardware. My comment: The adjustments of the brain hardware integrate RNA-mediated events that include gene duplication and fixation of amino acid substitutions. The nutrient-dependent gene duplications and substitutions link the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from microbes to man via their physiology of reproduction. The idea that everything known about nutrient-dependent…

Quantum physics, quantum biology, and quantum consciousness

Has anyone but me attempted to link light-induced amino acid substitutions from quantum physics to quantum biology in the context of the following works? All five published articles appear to be linked to quantum consciousness by the chemistry of nutrient-dependent pheromone-controlled feedback loops and chromatin loops that lead to increasing organismal complexity. The feedback loops are epigenetically linked from RNA-mediated events to protein folding and the stability of DNA in organized genomes. A Spectroscopic Mechanism for Primary Olfactory Reception Molecular…
