Left-Right Political Spectrum and the Human Gene Pool

Abstract

Felix Bast

Left-Right system is a well-known political spectrum apropos across the global politics. A number of social, cultural, linguistic, religious and economic attributes are identifiable in either of these two spectral extremities throughout the world. It is also widely known that intra- and inter-population heterogeneity of gene pools contributes in speciationthe split of genealogical lineage into two or more. However, a connection between Left-Right political spectra, or any political spectra for that matter, and the human gene pool remain consummately unknown. The present ab initio analysis reveal that the identifiable traits of left-right political spectra has strong and inherent potentials to directly affect the human gene pool to an extent to contribute in inter- and intra-population genetic heterogeneity, and, therefore, can affect processes of speciation and hybridization. The stereotypic leftist attributes can potentially result in high intra-population genetic heterogeneity, low inter-population genetic heterogeneity, and hybridization between divulging gene pools. On the other hand, rightist attributes can result in low intra-population heterogeneity, high inter-population heterogeneity, and ultimately the speciation. A plausible reason is the differential contribution of these traits towards assortative mating in human population via assortment of shared ancestry; i.e., population stratification and positive assortative mating due to homogamy. In the light of this central premise, repercussions of Left-Right political spectra on human evolution are deliberated. Argued here is that Left-Right political spectra have shared abstraction with Nurture-Nature axis of human perception. Therefore, it is plausible that Leftist and Rightist preferences are interposed by cerebral cortex and amygdala, respectively, and can very well have genetic rationale.
