My model of adaptive evolution per David Dobbs

The Social Life of Genes September 3, 2013 • By David Dobbs

Excerpt: Your DNA is not a blueprint. Day by day, week by week, your genes are in a conversation with your surroundings. Your neighbors, your family, your feelings of loneliness: They don’t just get under your skin, they get into the control rooms of your cells. Inside the new social science of genetics.

My comment: In 2000 Elekonich and Robinson detailed genetically predisposed hormone-organized and hormone-activated behavior in the context of our 1996 Hormones and Behavior review article “From Fertilization to Adult Sexual Behavior.” We included a section on molecular epigenetics and the focus was on how mammalian pheromones effect hormones that affect experience-dependent behavior. Finding that conserved molecular mechanisms in species from microbes to man are responsible for nutrient-dependent pheromone-controlled adaptive evolution should not be a surprise to anyone who does not believe in mutation-driven evolution. See for example a model of how nutrient stress and social stress epigenetically effect hormones that affect behavior in this mammalian model, which links what’s known about the molecular mechanisms of microbes to the molecular mechanisms of invertebrates, like the honeybee, and all vertebrates (sans mutations theory). The molecular mechanisms involve visual and auditory input during experience-dependent cause and effect directly attributed to olfactory/pheromonal input in all species. Attempts to make visual or auditory input causal have failed miserably.…
