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.
Desmond Morris Syndrome (DSM), where story-telling that incorporates evolutionary theory is better accepted than the basic principles of biology and levels of biological organization
immense gene networks enable epigenetic effects of nutrient chemicals and pheromones on stochastic gene expression, which lead to species-specific changes in behavior via transgenerational epigenetic inheritance.
Ingestive behavior and social behavior are odor receptor-mediated in all species (not just those that are sensitive to light) as would be expected due to the common molecular biology of all species.
…attention should be focused on the model organisms Bonasio and others, like me, have used to detail precisely how the differentiation of species, brains, and behaviors are driven by nutrient chemicals and pheromones.
The link to appetite regulation is from olfactory (and probably pheromonal) stimuli directly to the diet-responsive (and probably pheromone-responsive) hypothalamic neurogenic niche that controls nutrient chemical acquisition via its control of the dopaminergic and serotoninergic neuronal systems
Those who are interested in learning about cause and effect may therefore want to differentiate classical conditioning from operant conditioning. We can do so by referring to classical conditioning as Pavlovian conditioning, which it is, and referring to operant conditioning as willy-nilly silly conditioning, which it is.
