Let there be anti-entropic light (1)

terrarium eco system

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…

RNA-mediated epigenetic modification via DNA-methylation

human-evolution

I have repeatedly used the phrase “RNA-directed DNA methylation and RNA-mediated amino acid substitutions” in the context of links from the epigenetic landscape to the physical landscape of DNA in the organized genomes of species from microbes to man. See…

Environment epigenetically shapes the immune system

human-evolution

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…

Constrained evolution is ecological adaptation

translocated chromosome

See also: Unconstrained evolutionary innovability Ideas that evolution is not constrained can be compared to experimental evidence of biophysically constrained ecological adaptations. The most recent relevant open access published work from the Jakobsson lab is: TRIM28 Represses Transcription of Endogenous…
