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.

how much longer it will be until the “bird watchers” realize that the molecular mechanisms of how olfactory/pheromonal input epigenetically effects adaptively evolved behaviors are the same in species from microbes to man, and species of birds are included.
Shall we attribute to him the inability to see that metabolism and epigenetics converge with food odors and the metabolism of nutrient chemicals to pheromones that act on precisely the same molecular mechanisms of adaptive evolution found in species from microbes to man?
I think what they’ve just shown us exemplifies the molecular biology of epigenetically driven adaptive evolution.
The difference between an accurate portrayal of epigenetic effects and those that make claims of adaptively evolved behaviors “(sans epigenetics)” is a difference between fact and story-telling that goes back to the origins of the story more than 120 years ago.
