Nutrient chemicals in the ecological niche calibrate individual survival, and the nutrient chemicals metabolize to pheromones in the social niche, which standardize and control reproduction in all species.
…nutrient chemicals establish the ecological niche of different bacterial species and that nutrient calibrated receptor-mediated events link the metabolism of nutrients to pheromones that standardize and control speciation
The honeybee is a model organism for understanding the epigenetic link from food odors and social odors to neural networks of the mammalian brain, which ultimately determine human behavior.
Perhaps viruses are calibrating all mechanisms for both individual survival and for speciation across all species. If so, shall we credit them for all of Creation? What then can be said for “The Language of God?” 1532 genes and interactions among them are required for sexual reproduction that involves the mammalian placenta.

Here are the slides with text from a 20 minute-long presentation: Human pheromones: linking neuroendocrinology and ethology (revisited) 20th Biennial Congress of the International Society…
There is no direct effect of non-olfactory/pheromonal sensory input of the environment that would explain gene activation and the intracellular interactions in neurons that might result in de novo gene expression, which is why the most likely driving force for increased primate intelligence appears to be odors associated with nutrition and pheromones associated with socialization.
