The MicroRNAome Strikes Back: A Sokalian hoax (6)

The nature of nurture: Effects of parental genotypes Science  January 26, 2018

…nontransmitted alleles can affect a child through their impacts on the parents and other relatives, a phenomenon we call “genetic nurture.”

It doesn’t matter what they call it, since there is no defined boundary between genetics and epigenetics.

A calf may inherit those milk-boosting variants from its mother. But just because the calf carries them doesn’t mean they directly make the calves bigger.

Compared to other mammals, Dr. Bijma observed, human children are especially dependent on their parents — not just for food and other essentials, but for social development. So it stands to reason that they’d experience similar effects.

“Humans provide substantial care to their offspring, and so the nurture they create is very likely to have a genetic component,” said Dr. Bijma.

Dr. Harden said that taking account of genetic nurture could improve research on the effects of poverty on how children do in school, as well as studies of methods to improve educational attainment.

“It’s so obvious in retrospect, and so elegant,” she said. “A lot of people are going to say, ‘I can see my data in a new light with this.’”

…evolutionary science has now “moved on to such an extent” that she and Peter Saunders don’t really care anymore about trying to convince the neo-Darwinists.

The reporting on genetic nurture by Carl Zimmer appears to be a ploy to soften the impact of his past misrepresentations and the misrepresentations of all theorists and most so-called science journalists. He now reports on biophysically constrained energy-dependent events that link ecological variation to ecological adaptation in all living genera. See for example the The Bull Sperm MicroRNAome and the Effect of Fescue Toxicosis on Sperm MicroRNA Expression.
Included in the New York Times online article is a picture of a cow and a calf that tells less than half of what we detailed in From Fertilization to Adult Sexual Behavior (1996). The remaining details include how molecular mechanisms of RNA-mediated cell type differentiation are conserved in the bull.
Without food energy-dependent changes in the bull’s microRNAome, no one, including Carl Zimmer can get from the energy-dependent zinc spark at fertilization to the microRNAs in cow’s milk. And now, Carl Zimmer knows it!

Genes involved in transcription, RNA processing, and cell cycle regulation were particularly affected. The early embryonic arrest is not a consequence of a defective oocyte because depleting maternal BRG1 after oocyte development is complete by RNA interference (RNAi) also resulted in two-cell arrest. To our knowledge, Brg1 is the first gene required for ZGA in mammals.

But wait, there’s more than just RNA interference involved. The energy-dependent zinc spark is linked from the energy-dependent creation of microRNAs to the creation of  monoallelic olfactory receptor genes via the biparental contribution to chromosomal rearrangements. If not, Carl Zimmer and other science journalists cannot get from the epigenetic effects of food odors and pheromones to the feedback loops that link chromosomal rearrangements to the protection of all organized genomes from the virus-driven degradation of messenger RNA and all pathology.
If Carl Zimmer appears to have had a sudden epiphany that led him to see the light of evolution is actually sunlight in the context of ecological adaptation, his ability to see the how the facts extend to humans cannot be attributed only to a recent publication.

Comparisons of our maps with two LD-based maps inferred from data of HapMap populations of Utah residents with ancestry from northern and western Europe (CEU) and Yoruba in Ibadan, Nigeria (YRI) reveal population differences previously masked by noise and map differences at regions previously described as targets of natural selection.

Human population differences were linked to natural selection and the energy-dependent spark at fertilization. What, besides natural selection for energy-dependent codon optimality, could have been linked to the spark at fertilization?  Why would there be any questions about whether the findings in other animals extend to the findings on the transgenerational epigenetic inheritance of all morphological and behavioral phenotypes in species from yeasts to mammals that we reported in 1996? See our section on molecular epigenetics in  From Fertilization to Adult Sexual Behavior.
I wonder if Carl Zimmer was one of the people who may have seen my tweets during the past 28 days (80,000 impressions). There is no way to be certain that the timing of his epiphany is anything more than coincidental. But that doesn’t matter.
He is now well on his way to reporting the facts about biophysically constrained viral latency and biodiversity after decades of reporting on the pseudoscientific nonsense touted by neo-Darwinian theorists.
it seems just as likely that he has been following my blog posts here and is scared to death not to report the facts before the forthcoming conference: Mechanisms of Recombination After that, everyone in the world of intelligent science journalism will know that energy-dependent epigenetic effects link food odors and pheromones from feedback loops to biophysically constrained cell type differentiation and viral latency in all living genera.

Anyone who continues to report findings in the context of neo-Darwinian pseudoscientific nonsense about mutations and/or evolution is unlikely to be employed as a science journalist.
