dx.doi.org/10.1371%2Fjournal.pone.0113364 Excerpt: ... ecology is an important predictor for subspecies differences in social association, [and] DupB genotypes might be a good predictor for population rather than subspecies differences... as populations of the same subspecies may differ in the occurrence of these alleles... In the context of ecological variation, natural selection is for food, which is how this article indirectly links nutrient uptake from biodiversity to behavior in primates. Dobzhansky (1973) did that via what serious scientists now understand and what theorists cannot seem to grasp. Clearly, nutrient-dependent RNA-directed DNA methylation explains why ...the so-called alpha chains of hemoglobin have identical sequences of amino acids in man and the chimpanzee, but they differ in a single amino acid (out of 141) in the gorilla. However, fixation of the substitution via the pheromone-controlled physiology of reproduction is also required. Those who have touted the importance of oxytocin to differences in human behavior seem to have fallen behind the extant literature that links the differences to the epigenetic effects of food odors and social odors via GnRH-modulated feedback loops. The feedback loops, not oxytocin or other hormones, link the epigenetic landscape to the physical landscape of DNA in the organized genomes of all vertebrates via the conserved molecular mechanisms of nutrient-dependent pheromone-controlled reproduction that link species from microbes to man.
