The ISHE human ethology yahoo group moderator, Jay R. Feierman, continues his focus on evolutionary theory despite experimental evidence of RNA-mediated cause and effect. He posted a link to this article earlier today.
Evolutionary theory can provide a conceptual framework within which sex differences in human physiological or disease phenotypes can be understood.
My comment: At the advent of sex differences in the cell types of yeasts, all cell type differentiation has been detailed in the context of RNA-mediated events that link nutritional epigenetics to metabolic networks and to genetic networks that vary among individuals and species via links to their pheromone-controlled physiology of reproduction. The physiology of reproduction links the nutrient-dependent cell type differentiation in all cell types of all individuals of all genera.
Evolutionary theorists refuse to accept the facts about RNA-mediated sex differences in cell types because the facts refute their ridiculous theories.
See for comparison: From Fertilization to Adult Sexual Behavior
Parenthetically it is interesting to note even the yeast Saccharomyces cerevisiae has a gene-based equivalent of sexual orientation (i.e., a-factor and alpha-factor physiologies). These differences arise from different epigenetic modifications of an otherwise identical MAT locus (Runge and Zakian, 1996; Wu and Haber, 1995).
Linking HLA to the sense of smell alone (18, 19) would close a functional loop potentially subserving behavioral mechanisms of selection based on the sense of smell (20).
The link from nutrient-dependent RNA-mediated cell type differentiation to sex differences in species from yeasts to humans has been detailed during the past two decades. The only reports that prevent scientific progress come from human ethologists and other evolutionary theorists who cannot understand biologically-based cause and effect, which links epigenetic effects on hormones to the affect of hormones on behavior.
