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.

Epigenetic effects underlie sexual preferences IV

I include more information about the molecular mechanisms responsible for “…sex-specific regulation of miRNA levels that are known to influence sexually dimorphism of mRNA concentrations in the brains of mice” and in other species from microbes to man.

MicroRNA binds messenger RNA: Adaptive Evolution

This model of systems biology represents the conservation of bottom-up organization and top-down activation and the required reciprocity that links genes to behavior and back.

The logic of gene regulatory networks

As an alternative, we could continue to approach disorders of behavioral developmentas if nothing were known about epigenetic links between nature and nuture.

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.

Human pheromones: epigenetic effects

On10/11/12 I presented the evidence that this cause and effect relationship is common to species from microbes to man using the honeybee model organism as an example (at the Society for Social Neuroscience annual meeting in New Orleans.
