Nutrient-dependent / Pheromone-controlled Adaptive Evolution

A detailed model explains 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 (Kohl, 2012). That model is used to exemplify the effects of olfactory/pheromonal conditioning, which alters genetically predisposed, nutrient chemical-dependent, hormone-driven mammalian behavior and choices for pheromones that control reproduction via their effects on luteinizing hormone.
