Pheromones and exploration forge differences in twins and species

Excerpt: “Scientists have recognized that having distinct experiences within the same environment
might boost such personality differences, but that’s difficult to test in humans.”
My comment: How can the difference that is clearly forged by exploration in identical twins not be due to the same molecular mechanisms that explain the differences forged by exploration in wolves and dogs or other mammals? The differences are due to experience with food odors and pheromones See: 5-10,000 years of nutrient dependent pheromone controlled adaptive evolution.
