Behavior: The first response is RNA-mediated not genetically-determined
Diana Maria Petrosanu asked a question in an Evolutionary Psychology News discussion about Evolution’s Random Paths Lead to One Place. I’ve been very vocal in […]

Sex determination via conserved molecular mechanisms
1) Structure–function analysis of mouse Sry reveals dual essential roles of the C-terminal polyglutamine tract in sex determination (2014) Excerpt: “We demonstrate, using a combination of biochemical, cell-based, […]
Human Pheromones and sex differences in brain maturation
The effect of GnRH on secretion on luteinizing hormone/follicle stimulating hormone ratios and steroidogenesis, links social odors to brain maturation across species of mammals, as well as vertebrates. Experience-dependent brain-directed behaviors should be as variable as would be expected by the association between food odors and food preferences.
The Sex Lives of Insects: Part III
The “rules” of the required molecular biology involve ligand-receptor binding. For example, from yeasts to mammals, genetic conservation of the ligand: gonadotropin releasing hormone (GnRH), and the diversification of its receptor (GnRHR) are part of the rules.
