Chemical ecology drives adaptive evolution via:
- ecological niche construction
- social niche construction
- neurogenic niche construction
- socio-cognitive niche construction
This model of systems biology (“biological embedding”) represents:
- Nutrient chemical-dependent and social stress-induced intracellular changes in microRNA and messenger RNA homeostasis
- Intermolecular changes in DNA
- Experience-dependent stochastic variations in de novo gene expression for odor receptors
- The required gene-cell-tissue-organ-organ system pathway that links sensory input directly to gene activation in GnRH neurosecretory cells of the mammalian brain
- The required reciprocity that links gene expression to behavior that alters gene expression (i.e. from genes to behavior and back)
A model of how mutations might somehow cause adaptive evolution can now be compared to this model of nutrient chemical-dependent non-random adaptive evolution that is controlled by the epigenetic effects of pheromones on reproduction in species from microbes to man.
