Variability helps mammals to become invasive Excerpt: The authors argue that species exposed to a novel environment will have higher chances of surviving if they are variable and can therefore adapt to many different environmental conditions. My comment: Nutrient-dependent pheromone-controlled morphological and behavioral phenotypes are linked by microRNAs to adaptive radiation and to all of … MicroRNAs and invasive phenotypes
A universal trend of amino acid gain and loss in protein evolution Excerpt: “We cannot conceive of a global external factor that could cause, during this time, parallel evolution of amino acid compositions of proteins in 15 diverse taxa that represent all three domains of life and span a wide range of lifestyles and environments. … Deeply ingrained thoughts
Luis P. Villarreal has led the way towards discovery of the “origins of life.” He has helped to elucidate what is currently known about how the epigenetic landscape becomes the physical landscape of DNA in the organized genomes of species from microbes to humans. Kudos to Suzan Mazur for admitting that she missed learning about … Luis P. Villarreal tells it like it is
Cell type differentiation is included in all topics in biology, which is why it is important to understand what is currently known about top-down causation in the context of physics and chemistry. Taken together, physics, chemistry, and the conserved molecular mechanisms of biology link Drosophila to Octopuses and all other species on this planet via … RNA directed DNA methylation and cell types
Summary: Light-induced amino acid substitutions link cell type differentiation in plants to nutrient-dependent pheromone-controlled reproduction in animals via the biophysically constrained chemistry of protein folding. Protein folding is perturbed by mutations that limit the ability of organisms to adapt to ecological variation. Viruses contribute to mutations. The sun’s biological energy appears to supply the anti-entropic … Let there be anti-entropic light (1)
What Would Darwin Think About Modern Darwinism? Excerpt: “Imagine if Darwin could be transported to the present and learn what has become of his theory. What would excite him the most? Would anything disturb or disappoint him? TVOL has polled some of the most distinguished evolutionists of our day and we are pleased to provide … What if Darwin was not still dead?
Boston, land of…creationists? Excerpt: “For example, right now a creationist with a Harvard science degree is lecturing in Boston on Evolution: Bankrupt Science; Creationism: Science You Can Bank On. Obviously, Dr Nathaniel Jeanson is one of the fruit loops who plodded through a graduate program.” My comment: Dr Nathaniel Jeanson continues to politely lead the … How fast can evolutionary theory be changed?
See Sneaking up from behind and Physicists: Desperate Acts Biochemical communications as a prerequisite for dark photon communications? Excerpt 1) “…there have been innumerable links to various hot topics in biology about which I know virtually nothing. I have managed to catch only some key notions like behavior, nutrients, nutrinogenomics, nutrinogenetic signaling, pheromone, hormones, ecology. … Sneaking up from behind (2)
All in the (bigger) family Science 16 January 2015: Vol. 347 no. 6219 pp. 220-221 DOI: 10.1126/science.347.6219.220 by Elizabeth Pennisi Abstract: A decade of genetic data and other evidence has persuaded most researchers that insects and crustaceans, long considered widely separated branches of the arthropod family, actually belong together. The new arthropod tree puts hexapods—six-limbed … All of "like kind" in the (bigger) family
Environment, more than genetics, shapes immune system 1) –with my emphasis Re: “There’s nothing here that is revolutionary or requires rethinking of our assumptions about how the immune system functions…” My comment: They removed assumptions about cell type differentiation by linking differences in metabolic networks to genetic networks. They indirectly showed that ecological adaptations are … Environment epigenetically shapes the immune system
