Wikipedia refutes theistic evolution

RNA-Directed DNA Methylation Besides RNA molecules, a plethora of proteins are involved in the establishment of RdDM, like Argonautes, DNA methyltransferases, chromatin remodelling complexes and the plant-specific Polymerase IV and Polymerase V. All these act in concert to add a methyl-group at the 5′ position of cytosines. In contrast to animals, cytosines at all sequence context (CG, CHG, CHH) may get de novo methylated in plants. There is no such thing as de novo methylation. Methylation is energy-dependent. Virus-driven energy…

Dobzhansky 1973 and precision medicine

MicroRNA-34 directly targets pair-rule genes and cytoskeleton component in the honey bee Our findings point to miR-34-5p as novel regulatory component in the complex molecular cascade that governs insect segmentation and to a broader role of miRNAs in the early development due to the detection of mature transcripts from both 5p and 3p arms for several precursor miRNAs. Thus, this work encourages further investigation to pinpoint miRNAs as fine tuners of insect early development. Anna Di Cosmo‘s group took the…

Mutations: the “driving force” behind human brain complexity?

Evolutionary Psychology Crap in New Scientist There is a reason why domestic violence is so widespread, says David Buss, an evolutionary biologist at the University of Texas in Austin: it carries a selective advantage, tied with reproductive success. Larry Moran wrote: There’s something seriously wrong with evolutionary psychology. And there’s something seriously wrong with respectable science magazines who promote this crap. Are the science magazines that promote this crap respectable? I lost respect for anyone who still uses de Vries…

Energy-dependent RNA methylation (1)

“How often do we still hear that quantum effects can have little relevance in the study of biology, or even that we eat food in order to gain energy?” — Roger Penrose “We know, for instance, when we eat food nucleic acids can get into our cells. Also, there is a theory that our cells in the body keep sending out nucleic acids and one theory has it that it seems to correct the mistakes that other cells have suffered…

The Light and Darkness of “Evolution 2.0”

The light of evolution in the oft-cited work by Dobzhansky (1973) is the energy from sunlight. The sun’s biological energy links its anti-entropic virucidal epigenetic effects to RNA-mediated amino acid substitutions that differentiate all cell types in all individuals of all living genera. Excerpt from Dobzhansky (1973)  …the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla. ( p.…

Cancer: forward and reverse

The convergent cancer evolution toward a single cellular destination Abstract excerpt: …cancer evolution is a directional process toward a defined cellular destination, a finding reconciling development and evolution, the two seemingly incompatible philosophies both adopted by the cancer research community, and also raising new questions to evolutionary biology. My comment: The idea that cancers evolve and the idea that species evolve are not compatible. Taken  together, the incompatible ideas that have been adopted by cancer researchers led to 32 years…

The stability of organized genomes

Beyond neo-Darwinism—an epigenetic approach to evolution Excerpt from 6/21/79 The evidence suggests… that a relative lack of natural selection may be the prerequisite for major evolutionary advance. Nutrient-dependent/pheromone-controlled adaptive evolution: a model. Excerpt from 6/14/13 (34 years later) …the epigenetic ‘tweaking’ of the immense gene networks that occurs via exposure to nutrient chemicals and pheromones can now be modeled in the context of the microRNA/messenger RNA balance, receptor-mediated intracellular signaling, and the stochastic gene expression required for nutrient-dependent pheromone-controlled adaptive…

Nothing new under the sun, except pseudoscientific nonsense

On the Importance of Being a Methodological Naturalist Posted on November 5, 2014 by David Sloan Wilson Excerpt: “…consider the flying spaghetti monster, a deity invented to poke fun at religion. It is ridiculous, but is there any way to prove that it doesn’t exist?” Conclusion: “If religious believers abandon methodological naturalism, then they are forced to deny not only the laws of physics and the facts biological evolution, but the histories of their own religions.” My comments: DS Wilson is…

Don't tell the Creationists

Misquoting Science in the Texas Textbook Battles James A. Shapiro Author, ‘Evolution: A View from the 21st Century’; Professor of Microbiology, University of Chicago Posted: 12/05/2013 3:57 pm Excerpt: “Uncovering the molecular mechanisms by which living organisms modify their genomes is a major accomplishment of late 20th Century molecular biology.” Collectively, I call these processes Natural Genetic Engineering. Symbiogenetic cell fusions, horizontal DNA transfer, mutagenic DNA repair, reverse transcription of RNA into DNA, mobile genetic elements, interspecific hybridization and whole…
