RNA-mediated epigenetic modification via DNA-methylation

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 for example: RNA-mediated, with links to ~200 blog posts. In the introduction to my 2012 RNA-mediated epigenetic modification via DNA-methylation

Extensive molecular evidence vs ridiculous theories

Mosquito Genomes Galore Whole-genome sequences of 16 different mosquito species reveal rapid evolution and could inform malaria research. By Ruth Williams | November 27, 2014 Excerpt: “…mosquitoes are rapidly evolving, exhibiting high degrees of gene gains, losses, shuffling, and even transmission between closely related species.” It is the reports on rapid evolution of insects that Extensive molecular evidence vs ridiculous theories

Eliminating evolutionary theory

Does evolutionary theory need a rethink? Excerpt 1) “…the theory neglects key processes, say Kevin Laland and colleagues.” My comment: “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans (Keller et al., 2007; Kohl, 2007; Villarreal, 2009; Vosshall, Wong, & Axel, 2000).” — Human Eliminating evolutionary theory

Pattern recognition and conserved receptors (TAARs)

Olfactory Receptor Patterning in a Higher Primate Excerpt: We found that TAARs are also expressed in the macaque OE, suggesting that these receptors may also function as chemosensory receptors in the human nose. My comment: The article links the senior author’s prior works from nutrient-dependent RNA-mediated events and the de novo Creation of odorant receptor Pattern recognition and conserved receptors (TAARs)
