Integrating the chemical ecology of the social brain’s adaptive evolution allows it to be viewed – along with adaptive evolution of the CNS – at four levels of niche construction: 1) ecological, 2) social, 3) neurogenic, and 4) socio-cognitive.
No neurogenic niche does not mean no behavior, and no socio-cognitive niche only means that the unconscious affects of sensory stimuli on hormones and behavior will predominate.
Why does anyone need to explain free will as the absence of human cannibalism in most societies, when it is largely absent across adaptive evolution that has occurred via ecological, social, neurogenic, and socio-cognitive niche construction?
the treatment with nutrient chemicals works as would treatment with pheromones, which are expected to alter the same hypothalamic neurogenic niche responsible for GnRH-directed changes in luteinizing hormone and hippocampal neurogenesis
The problem with multi-level selection in humans seems likely to be one that is due to ignorance about the role of pheromones in the context of ecological, social, neurogenic, and socio-cognitive niche construction.
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.
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.
