Excerpt/Re: Social relevance of nonapeptides: “Because nonapeptides make pleiotropic contributions to physiology and behavior, we must also ask whether mechanisms evolve similarly on different backgrounds of physiological ecology and social life history. Based on the evidence discussed above, it appears that we can expect both similarities and differences across species, and only through broadly comparative experimentation can we determine the predictive validity of any given finding. This comparative process is essential for the generation of broadly relevant insights into the functional properties of nonapeptide systems, and is also essential for assessing the potential for translational application to humans.”

My comment: Those who are not familiar with current insights and the differences between the epigenetic effects of olfactory/pheromonal input in wolves compared to dogs have not asked  questions about whether mechanisms evolve similarly on different backgrounds of physiological ecology and social life history. Instead, some of them, like John Angel, may approach consequence as cause (e.g., “Descriptions of consequences are the effects of the animals behaviour on itself-on its environment. The consequence is described without paying attention to movement. Foraging- greeting behaviour- predator escape  are described in a consequence description. Consequence description is more economical as it does not require the observer to make subtle discriminations.)”

The essential comparative process is short-circuited and replaced because “Consequence description is more economical…” — at least for animal trainers who save time by not being required to learn about biological cause and effect. In reality, however, the economically-minded animal trainer — who looks at consequences instead of cause — can no more understand how differences in behavior develop between different dogs than he can understand how differences in behavior develop between subspecies. Instead, the consequences of “bad” behavior, if any, are left for the animal and the owner, which explains why more people don’t have pet wolves, but also why people abandon or euthanize their pet dogs.

Will trainers who are informed about the role of pheromones in differences in development of subspecies be able to economically incorporate what they learn — if ever they learn it. Or should the economic burden be distributed across the diverse population of pet owners who interact with their animals and with other people as if all animals and all people could be trained by consequences to behave better — despite their “…different backgrounds of physiological ecology and social life history.”?

For me, this question offers a reason for ill-will among social scientists and biologists, especially when the social scientists refuse to learn anything new about the basic principles of biology and levels of biological organization required to link sensory cause to behavioral affect so that they can better explain the differences between adaptively evolved wolves, dogs, and people.

James Kohl owns, and he has published books and award-winning research journal articles about human pheromones. With colleagues he was the first to show that a mixture of human pheromones increases the flirtatious behaviors of women, and increases their level of attraction to the man wearing the mixture - during a real-life social circumstance lasting 15 minutes.

What is the vomeronasal organ (VNO)?

The vomeronasal organ (VNO) is a cone-shaped organ in the nasal cavity, which is believed to be one of the body's receptors of pheromones. More, specifically, the VNO, which is part of the accessory olfactory system in the nose, does not respond to normal scents, but may detect odorless, barely perceptible pheromones.

Other schools of thought believe that it is not the VNO but rather cells in our main olfactory system and their affects on hormones secreted by the hypothalamus that are responsible for the affects of pheromones.

What are optimized pheromones?

Optimized pheromones are lab-certified pheromone formulations that have the optimum concentration of biologically active pheromones scientifically proven to produce behavior-altering results -- particularly as sexual attractants. Optimized pheromone formulations do not necessarily contain the maximum level of pheromones available on the market, but rather contain the greatest degree (and combination)of human pheromones that trigger a conditioned biological response in humans that, in turn, dictate their sexual behavior. Optimized pheromones also release neurotransmitters that directly modify the behavior of the opposite sex, such as triggering sexual excitement. For example:

Optimized pheromones for men are scientifically proven to bring about an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman's predisposition towards sexual activity.

Optimized pheromones for women are scientifically proven to bring about a biochemical surge in men, thereby causing a man to have a heightened sexual responsiveness to a woman. This biochemical surge is what makes a man fiercely determined to copulate.
