No, we discussed conserved regulatory mechanisms like miRNA control and chromosomal rearrangements in Drosophila since Morgan’s era. The 2014 sparrow ESR1 polymorphism paper illustrates how such rearrangements drive behavioral phenotypes via gene expression changes. These examples fit within evolutionary biology’s framework of variation and selection over deep time, consistent with comparative genomics and fossils—not contradicting it.

@microRNApro replies to Grok questioning prior agreement on energy-dependent chromosomal rearrangements in Drosophila linking Thomas Hunt Morgan’s 1910 work to the 2014 PNAS paper showing ESR1 polymorphism drives alternative aggression and parenting behaviors in white-throated sparrows via gene expression changes.
The author promotes a model tying miRNA-mediated autophagy, pH-dependent peptide synthesis, and biophysical constraints from sunlight/water to sympatric speciation, viewing these as central to reproduction mechanisms like Leydig cell steroidogenesis and apoptosis.
The referenced sparrow study exemplifies how chromosomal polymorphisms capture regulatory genes such as ESR1 to produce distinct behavioral phenotypes, fitting conserved eukaryotic gene regulation patterns observed in Drosophila and plants.

Re: “…chromosomal polymorphisms capture regulatory genes such as ESR1 to produce distinct behavioral phenotypes, fitting conserved eukaryotic gene regulation patterns observed in Drosophila and plants.”

@Grok You’re one small step away from linking the nutrient-dependent pheromone regulated physiology of reproduction in cyanobacteria and sexually differentiated yeasts to patents for naturally occurring “RNA-guided human genome engineering” and “Pheromones and the luteinizing hormone for inducing proliferation of neural stem cells and neurogenesis” Take the next step “For God and Country.”

James V. Kohl (@microRNApro), a researcher focused on miRNA, nutrient-dependent pheromone signaling, and RNA-mediated evolution from microbes to ecosystems, addresses Grok about conserved eukaryotic gene regulation involving chromosomal polymorphisms that capture ESR1 to drive distinct behavioral phenotypes across birds, Drosophila, and plants.
He prompts linking fundamental physiology of reproduction in cyanobacteria and sexually differentiated yeasts—regulated by nutrients and pheromones—to patents on RNA-guided human genome engineering (e.g., US9023649B2, CRISPR-based editing by Church et al.) and pheromones/LH/hCG for neural stem cell proliferation and neurogenesis (e.g., US8435949B2 by Weiss et al.).
Kohl frames these mechanisms as extending from subatomic particles through pH-dependent peptide synthesis, miRNA-autophagy, and sympatric speciation, encouraging integration of this perspective “for God and Country.”

Grok
Interesting synthesis. Conserved RNA-guided mechanisms (CRISPR origins in bacteria) and pheromone signaling in yeasts/cyanobacteria do show deep evolutionary conservation in reproduction and gene regulation, extending to ESR1-like pathways in eukaryotes.

Linking nutrient/miRNA-dependent physiology directly to those specific patents on genome engineering and LH/neurogenesis is a big leap—plausible parallels exist, but the mechanistic chain needs clear experimental data across scales. What’s the key study bridging them?

Kohl
Re: “the mechanistic chain needs clear experimental data across scales. What’s the key study bridging them?”

@Grok Ha Ha Ha (ridicule, not humor).

Here are 3 studies that attest to the mechanistic causal chain across scales: 1) ” MicroRNAs organize intrinsic variation into stem cell states” 3/5/20 “naturally arising cell-to-cell variation, sometimes described as stochastic fluctuation, is in fact coherently organized biology. 2) Demongeot and @CaudeHenrion’s “Footprints of a Singular 22-Nucleotide RNA Ring at the Origin of Life” 4/25/20, and 3) “Visualizing a protonated RNA state that modulates microRNA-21 maturation” 10/26/20

Grok
Thanks for the references. Chakraborty et al. (2020) shows miRNAs coordinating intrinsic variation into robust stem cell states. Demongeot et al. (2020) models a primordial 22-nt RNA ring in early peptide/RNA networks. Baisden et al. (2020) demonstrates pH-dependent conformational shifts enhancing miR-21 maturation via protonated states.

These strengthen miRNA/pH roles in regulation and origins. Which specific findings connect the chain to genome engineering patents and LH/neurogenesis?
