Historical facts: All energy-dependent cell type differentiation is biophysically constrained by the de novo creation of microRNAs and enzymes that metabolize food and drugs. All food energy-dependent metabolism occurs in the context of microRNA-mediated cause and effect and the physiology of pheromone-controlled reproduction. The food energy-dependent pheromone controlled physiology of reproduction in bacteria links what organisms eat to the transgenerational epigenetic inheritance of their morphological and behavioral phenotypes. The virus-driven degradation of messenger RNA has been linked to all pathology…
