A diet-reponsive neurogenic niche links nutrient chemical intake to receptor-mediated brain development in mammals. Glucose regulates the hormone secreting nerve cells in this niche, which links it and other nutrient chemicals to levels of luteinizing hormone (LH) and brain development.
The 10-page article details how the epigenetic influences of nutrient chemicals and pheromones are responsible for adaptive evolution of the required ecological, social, and neurogenic niche construction
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.
Taken together, these two open-access articles from the supplement offer a concise and reasonably accurate overview of the receptor-mediated events that are required for adaptive evolution.
If you want to know where love is, you can find out by following the path from your nose to the brain via the epigenetic effects of food odors and pheromones on hormone-secreting nerve cells, not one that somehow links pictures to love and sexual desire. There’s no model for that!
My cognitive niche, for example, allows me to recognize patterns, like the design in biology that is apparent in the adaptive evolution that results from ecological, social, neurogenic, and cognitive niche construction.
My idea is that nutrient chemical-dependent ecological niche construction and pheromone-dependent social niche construction contribute equally to the neurogenic niche construction that is responsible for adaptive evolution, development of the mammalian brain, and construction of our socio-cognitive niche.
GnRH also links nutrient chemicals and pheromones directly to adaptive evolution via the required ecological, social, neurogenic, and cognitive niche construction evidenced by the apparent design in biology.
The arrogance of evolutionary theorists who have yet to learn anything about how natural selection continues to epigenetically alter our DNA via the effect of nutrient chemicals and pheromones is like a weight to be dragged forward into a new age of explanations coming from molecular biology.
Olfaction is the ‘sensing agent’ of natural selection, because natural selection requires selection of nutrient chemicals that metabolize to pheromones that control reproduction and species diversification.
