Excerpt: "Anthropologist Helen Fisher says love is an addiction.... We may be predisposed to develop this addiction, like our pleasure hormones so readily available at the slightest touch and our ability to smell subtle pheromones."

My comment: Helen Fisher said this about The scent of eros: mysteries of odor in human sexuality (by Kohl and Francoeur 1995): "This is science at its best, with adventure, ideas, and lots of facts".

Kohl (2012) says this: ...an environmental drive evolved from that of food ingestion in unicellular organisms to that of socialization in insects. ...in mammals, food odors and pheromones cause changes in hormones which have developmental affects on sexual behavior in nutrient-dependent, reproductively fit individuals...

This model of systems biology represents the conservation of bottom-up organization and top-down activation via: Nutrient-dependent stress-induced and social stress-induced intracellular changes in the homeostatic balance of microRNA(miRNA) and messenger RNA (mRNA)

MicroRNAs...regulate insulin sensitivity

Is there an animal model that does not predict the adaptive evolution of our genetically-predisposed, nutrient chemical-dependent, pheromone-controlled hunger for love? If not, Helen Fisher is correct; the book I co-authored is science at its best because it includes the facts about human pheromones and their effects on the hormones that affect lust and love linked to food odors and pheromones. Is there another animal model for that?
