Extension to people of the molecular biology common to all species explains how cerebral activation of hormone-secreting neurons and processes commonly attributed to individual components of the model, like genes or hormones, results in genetically predisposed phenotypic expression
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.
These results extend the requirement for mammalian pheromone-dependent myelination to human infants raised with minimal social contact. The absence of social odors (the pheromones) shows up in behavior caused by their otherwise “normal” epigenetic effects.
Kudos to them for moving us forward and away from random mutations theory to an era where geneticists and neuroscientists can examine sensory cause and effect in the proper perspective of an epigenetic continuum of unconscious affects on genomic interactions…
…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.
Most psychologists seem unwilling to admit they don’t know the difference between Pavlovian/classical conditioning and operant/respondent conditioning, perhaps because that would be an admission that they have never treated their clients effectively, which is well known to others whose psychological treatment has failed.
What the honeybee queen eats determines her pheromone production. Her pheromones determine everything else about the social interactions of the colony including the neuroanatomy of the worker bees’ brains.
The idea that ecological niches and social niches are the determinants of neurogenic niches, like those that develop with exposure to food odors and social odors, is one that is important to consider whether we intend to look at pharmacogenomics or to better understand the development of human behavior in the context of epigenetic effects of odors on brain development.
The direct effect of food odors and social odors on signalling pathways makes the epigenetic effects of chemical cues as important to the understanding of human behavior as they are to the understanding of behavior in every other species. This is especially true for placental mammals.
