Virus-driven cell type differentiation

A Nutrient-Driven tRNA Modification Alters Translational Fidelity and Genome-wide Protein Coding across an Animal Genus Abstract excerpt: These results reveal a strikingly direct mechanism by which recoding of entire genomes results from changes in utilization of a nutrient. Expression of multiple horizontally acquired genes is a hallmark of both vertebrate and invertebrate genomes Conclusion: Although Virus-driven cell type differentiation

Bio-CHEMICAL complexity

There is nothing about the enormous biochemical complexity of the human brain that suggests its complexity could be reduced to a theory in which domain specificity was adaptive in any species from microbe to man.
