Nutrient-dependent / pheromone-controlled social structure

Wang et al (2013) make it clearer that epigenetic modifications of genes found in social chromosomes entered continuum of adaptive evolution before the sex chromosomes.

Epistasis as the primary factor in molecular evolution

“… the “mutational vicinity” is probably found in the molecular vicinity of a “metabolic niche”.

Epigenetic maintenance of transcription / neuronal migration

I think what they’ve just shown us exemplifies the molecular biology of epigenetically driven adaptive evolution.

Creating new genes (and controlling diversity)

The epigenetic effects of nutrient chemicals on gene duplication and species diversity and the ability to metabolize nutrient chemicals is controlled by the metabolism of the nutrient chemicals to pheromones that epigenetically control reproduction in all species

The end of random mutations theory

most people should be closer to thinking in terms of adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction, which makes sense.

“Just-So” stories vs scientific explanations

The inability to think their way through from gene activation to behavior that activates genes (e.g., in cells) results in their inability to understand eco-evolution…

Human pheromones: an epigenetic continuum from microbes to mammals

The only explanation for adaptive evolution with any across species explanatory power is found in my details of the epigenetic effects of olfactory/pheromonal input on intracellular signaling and stochastic gene expression…

Human pheromones, the social brain and simple math computations

Integrating the chemical ecology of the social brain’s adaptive evolution allows it to be viewed – along with adaptive evolution of the CNS – at four levels of niche construction: 1) ecological, 2) social, 3) neurogenic, and 4) socio-cognitive.

Niche construction: ecological, social, neurogenic, and socio-cognitive

No neurogenic niche does not mean no behavior, and no socio-cognitive niche only means that the unconscious affects of sensory stimuli on hormones and behavior will predominate.
