Science vs nonsense (and scholarship) update: comments approved 11/4/13

I discussed other Science vs nonsense comments accepted for publication to the Science site here. The following comment builds upon the others.

My comment (accepted for publication to the Science site on 11/4/13) : Re: Mosaic Copy Number Variation in Human Neurons.

The neuronal copy number variation (CNV) can be traced to its origins in yeasts, when epigenetically-effected CNVs enable self vs non-self recognition at the advent of immune system function and sexual reproduction, albeit sans neurons.

Olfactory/pheromonal input is subsequently associated with alternative splicings that link the epigenetic ‘landscape” to the physical landscape of DNA in the organized genome of species from microbes to man via CNVs. During adaptive evolution the CNVs in neurons are directly linked from olfactory/pheromonal input via ecological, social, neurogenic, and socio-cognitive niche construction. For example, neuronal niche construction in nematodes proceeds across species via conserved molecular mechanisms required for the thermodynamics of seemingly futile nutrient-dependent cycles of protein synthesis and degradation to species-specific pheromones. Pheromones control the physiology of reproduction and help to control nutrient-dependent organism-level thermoregulation.

In a mammal, see for example: Odorant receptor gene choice and axonal wiring in mice with deletion mutations in the odorant receptor gene SR1. However, see also my ISHE Summer Institute poster session for details that eliminate mutations from further consideration in adaptive evolution. To do that I used examples from nematodes, insects, other mammals, and a human population that arose in what is now central China during the past ~30,000 years.

Non-random experience-dependent adaptive evolution occurs due to a thermodynamically controlled single base pair change and nutrient-dependent amino acid substitution best exemplified in the mouse model via what is neuroscientifically known about nutrient-dependent pheromone-controlled reproduction.
