“This ever-growing body of evidence points to a critical role of scent in guiding the social behavior and reproductive function throughout the primate order.
“…these data demonstrate a critical role of male-sourced E2 in these major mammalian pheromonal effects.”
“Olfactory signals reach brain areas controlling reproductive behaviors in birds.”
“A multi-level regulatory network consisting of such mechanisms as modular utilization of protein domains, alternative splicing and epigenomic modifications of DNA has been the driving force behind the wide radiation, rapid evolution and evolutionary success of eukaryotic organisms.”
“Olfactory acuity in the population is most strongly influenced by age, followed by gender. We also show a large number of diverse correlations between demographic factors and the perception of individual odours that may reflect different prior experiences with these odours between demographic groups.”
- Testosterone increases circulating dehydroepiandrosterone sulfate levels in the male rhesus macaque
“The adrenal steroid dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are two of the most abundant hormones in the human circulation. Furthermore, they are released in a circadian pattern and show a marked age-associated decline. Adult levels of DHEA and DHEAS are significantly higher in males than in females, but the reason for this sexual dimorphism is unclear.”
Nearly everything known about cell type differences in species from microbes to man has been learned in the past few years. We predicted most of what has been learned about the molecular epigenetics of cell type differentiation in our 1996 review: From Fertilization to Adult Sexual Behavior. My other published works, presentations, and this blog continues to explore that paradigm-shifting work and show how ecological variation leads to ecological adaptations.
Already, more than 1000 blog posts have integrated scientific discoveries as they have appeared. Here, I will continue to explain how new scientific discoveries link food odors and pheromones to differences in the development of behavior via conserved molecular mechanisms in species from microbes to man. Intelligent discussion among self-identified participants will be encouraged.
Intro to topics/catagories?
Perfuming the Mind provides details aspects of molecular biology that link human pheromones to what is known about the molecular neuroscience of the mind. It is resource of technical information for those who want to learn more than social scientists will ever tell you about the biology of behavior. Some content is directed towards a general audience, but most people may find they are in ‘over their head’ unless they have an interest in learning about accurate representations of how differences in behavior develop.
Perfuming the Mind: The Biological Logic of Physical Attraction is a brief non-technical introductory article about the effect of human pheromones on hormones and human behavior. It links two award-winning technical reviews across decades of additional information to what is currently known about how pheromones effect hormones that affect behavior.
Most information about animal behavior comes from model organisms and it shows that “…the only worthwhile biology is molecular biology. All else is “bird watching” or “butterfly collecting.” Bird watching and butterfly collecting are occupations manifestly unworthy of serious scientists!” — Dobzhansky (1964)
Here you will find serious science. I co-authored Human pheromones: integrating neuroendocrinology and ethology, which won the “Zdenek Klein for human ethology” in 2001. Excerpt: “The effect of sensory input on hormones is essential to any explanation of mammalian behavior, including aspects of physical attraction.”
Diseases & Disorders
Comparative approaches in evolutionary psychology: molecular neuroscience meets the mind won the same award in 2002. Excerpt: “Evolutionary psychologists often overlook a wealth of information existing between the proximate genotypic level and the ultimate phenotypic level. This commonly ignored level of biological organization is the ongoing activity of neurobiological systems.”
From Fertilization to Adult Sexual Behavior, which I co-authored in 1996, links human pheromones to the biologically-based organization of human behavior. Evolutionary theorists have continued to overlook obvious links from food odors and human pheromones to behavior while touting their theories about mutation-initiated natural selection and the evolution of biodiversity. Here you will find accurate representations of biological facts that refute evolutionary theory. Without being labeled a “Creationist,” you can discover what makes your mind different by using information about what’s known from molecular neuroscience in the context of odors that perfume the mind.
Biophysical constraints that prevent mutations from leading to increasing organismal complexity have been virtually ignored by population geneticists. However, an extreme example of this ignorance was manifested when one book author did not ignore the biophysical constraints. Instead, he concluded that: “… genomic conservation and constraint-breaking mutation is the ultimate source of all biological innovations and the enormous amount of biodiversity in this world.” Mutation-Driven Evolution (p. 199).
In 2014, Israeli middle-schools began to teach the theory of evolution. They now use the theory as an example of how to compare what is known about ecology to ideas that have no explanatory power. Theories do not address how ecological variation leads to ecological adaptations. Instead, theorists claim that mutation-initiated natural selection leads to the biodiversity manifested in ecological adaptations via evolution. How does evolution do that? If you start with a theory and force mutations and natural selection to fit into the context of the theory, you can explain what happened as if you understood biologically-based nutrient-dependent pheromone-controlled epigenetic cause and effect. But, sooner or later people will realize that you explained nothing about how evolution occurred. You simply insisted it did and then tried but failed miserably to explain biodiversity.
Claims that human pheromones don’t exist have repeatedly been made by those who have no understanding of what they are claiming. Conserved molecular mechanisms link food odors and pheromones to the biology of behavior in all species. If a species responds to food odors, the members of that species must also respond to species-specific pheromones. If not, the species is not a species because the physiology of species-specific reproduction is controlled by the metabolism of nutrients to pheromones, which links food odors and pheromones to biodiversity in all species. Those who claim human pheromones don’t exist have no insight and do not understand what’s common about common scents. For example, food odors and pheromones epigenetically effect hormones that affect behavior in all vertebrates and invertebrates.
What’s in the News
The overwhelming amount of news from scientific sources is confusing. It forces most people to specialize and only look at information that pertains to their area of expertise. This means they typically do not integrate what they read into any representation that might make what is in the news reflect what is actually known about biologically-based cause and effect. Instead, bits and pieces of information that often conflict with the representations being made continue to entice the scientifically illiterate, and lead them to believe in self-proclaimed experts whose knowledge-base is extremely limited. Meaningless results are meaningfully interpreted and that’s what most people learn about from the news.
“Neuroendocrinology is the study of the interaction between the nervous system and the endocrine system, including the biological features of the cells involved.” ” The focus of ethology is on animal behaviour under natural conditions
Searching for the Mind with Jon Lieff, M.D. also provides details that help to link human pheromones, hormones, and perfuming the mind from cell type differentiation in all cells of all inidividuals of all species to the molecular neuroscience of the mind via the conserved molecular mechanisms of biologically-based cause and effect.
