Nutrient--dependent / pheromone--controlled adaptive evolution: a model
06-14-2013 2:42 PM

Citation is: Kohl, JV (2013) Nutrient--dependent / pheromone--controlled adaptive evolution: a model. Socioaffective Neuroscience & Psychology, 3: 20553

Background: The prenatal migration of gonadotropin releasing hormone (GnRH) neurosecretory neurons allows nutrients and human pheromones to alter GnRH pulsatility, which modulates the concurrent maturation of the neuroendocrine, reproductive, and central nervous systems, thus influencing the development of ingestive behavior, reproductive sexual behavior, and other behaviors.
Methods: This model details how chemical ecology drives adaptive evolution via 1) ecological niche construction, 2) social niche construction, 3) neurogenic niche construction, and 4) socio-cognitive niche construction. The model exemplifies the epigenetic effects of olfactory/pheromonal conditioning, which alters genetically predisposed, nutrient--dependent, hormone--driven mammalian behavior and choices for pheromones that control reproduction via their effects on luteinizing hormone (LH) and systems biology.
Results: Nutrients are metabolized to pheromones that condition behavior in the same way that food odors condition behavior associated with food preferences. The epigenetic effects of olfactory/pheromonal input calibrate and standardize molecular mechanisms for genetically predisposed receptor--mediated changes in intracellular signaling and stochastic gene expression in GnRH neurosecretory neurons of brain tissue. For example: glucose and pheromones alter the hypothalamic secretion of GnRH and LH. A form of GnRH associated with sexual orientation in yeasts links control of the feedback loops and developmental processes required for nutrient acquisition, movement, reproduction, and the diversification of species from microbes to man.
Conclusion: An environmental drive evolved from that of nutrient ingestion in unicellular organisms to that of pheromone--controlled socialization in insects. In mammals, food odors and pheromones cause changes in hormones such as LH, which has developmental affects on pheromone--controlled sexual behavior in nutrient--dependent reproductively fit individuals across species of vertebrates.
