The combination of chemicals in the mixture and the effects of the mixture on women’s behavior enables us to make the claim that the mixture is a mixture of human pheromones.
It’s interesting to see Feldman indicate that “human movements drove a new form of natural selection” as if there was ever any other form of natural selection that had been detailed across species by anyone else.
Patisaul et al (2012) makes it clearer the “The role of oxytocin, for example, must be explained in the context of how pheromones, food odors, and endocrine disruptors epigenetically effect sociosexual behavior.”
This study indicates that copulins affect males both in physiology and behavioral response.
… it is the molecular biology common to all species that assures us olfaction and odor receptors provide a clear evolutionary trail, which can be followed from unicellular organisms to insects to humans.
It appears to be the epigenetic effect of mammalian pheromones, including human pheromones, on luteinizing hormone and white matter/gray matter ratios that is responsible for the differences in brain growth.
“The findings also provide a framework for understanding fascinating evolutionary questions, such as why humans of different ethnicities have distinct facial features and how these are embedded in our genome.”
…this complex ability in bacteria that suppress reproduction with pheromones when insufficient nutrients are available led me to sponsor the video game “Bacillus.”
