Understanding species differences

Biology, Brains and Behavior, Genetics

Genes Aren’t Just Architects; They’re Actors by David Dobbs • 

Excerpt: “Robinson and others have for years been waving their hands, pointing at results like this, and arguing that the endgame in genetics is not in differences in what genes we carry, but — especially when most of our genes our shared — in differences in how and when the shared genes express themselves. This is important in understanding differences within a species, whether it be honey bees or humans.”

My comment: In 2000 Elekonich and Robinson extended our 1996 mammalian model of molecular epigenetics and hormone-organized / hormone-activated behavior to insects, with the honeybee as the model organism. I’ve since linked human pheromones to the conserved molecular mechanisms of species from microbes to man in two published papers:

Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behavior (2012)

Nutrient-dependent/pheromone-controlled adaptive evolution: a model (2013)

I’m not sure how anyone else could explore the topic of species differences in more detail than I have provided during that past two decades since my first presentation to a scientific forum (in 1992) and book publication in 1995. I am sure that the differences in the brain and social behavior of insects and humans are nutrient-dependent and pheromone-controlled. There is no other model for that! The fact that the model is fully detailed in the journal ‘Socioaffective Neuroscience & Psychology’ may be the best indicator that David Dobbs is on the same track as I have been since I first began researching human sexuality in the early 1980s.
