Three recent journal articles examine what some people might believe is a reduced human sense of smell compared to other animals. 1) Opposites attract: MHC-associated mate choice in a polygynous primate. 2) Human Ability to Recognize Kin Visually Within Primates.
A news article helps to bring home the point. So does the fact that other primates recognize differences in genetic diversity by using their 3) sense of smell and pheromones. If, as is frequently stated, humans have a reduced sense of smell compared with other species, we should be unable to recognize and differentiate among olfactory/pheromonal stimuli from other humans.
The fact that we have the same abilities as other animals strongly suggests that olfactory/pheromonal stimuli condition our response to visual input that’s consciously associated with the visual appeal of another person.
James V. Kohl detailedl how quantized energy-dependent microRNA biogenesis links the pheromone-controlled physiology of reproduction to biophysically constrained viral latency and healthy longevity. Links from what organisms eat to the enzyme-dependent metabolism of food also link metabolic networks to microRNA-mediated genetic networks in the context of RNA interference. Drug therapies alter RNA interference by altering cell type differentiation in all cells of all individuals of all species. For comparison, during the past 26 years, Kohl has detailed how the chemistry of protein folding is biophysically constrained at every level of biological organization by conserved molecular mechanisms.
