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.

A newly discovered hypothalamic neurogenic niche in the brain

The authors are among many, who seem to have missed a likely epigenetic link from maternal and/or acquired ferritin deficiency to thyroxine transport, brain development, and behavior.

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.
