Hyperborean Perspective
The three root types of genetic heritage (in this context, the concept of "genetics" may encompass the non-material attributes and some hidden variables)
1. The base Pasu, or the animal-man, son of clay etc. A result of the passive evolution of the archetypally guided and modelled soul/matter, which is an eventual result of the initial, external perturbations that precede all manifestations, and some local modifications, but lacking the sufficient anti-entropic infusion, particularity and guidance to evolve past the most primitive threshold. Dominant and defining root of the lower races.
2. The synthetic, approximative genes (covenant) and the collective egregore (hive-mind) of the Jews and other "chosen people". Local nodes and worker drones of the cybernetic Golem. Dominant and defining root for them and their hybrids, capable of integrating (approximating, mimicking) some echoes and traits of the next type to a lesser extent and order of magnitude via phagocytosis and material hybridization. Under certain conditions, also capable of mentally extending to other types via memetics, cultural highjacking and hypnosis. Surely you have met people that have no Jewish heritage but are mentally indistinguishable from them, as well as those that appear like possessed by their mental constructs.
3. The noble born Aryans and other higher races/species, the sons of smokeless fire and descendants of the Gods. Reflecting the particularized anti-entropic component needed to evolve the higher man into a divine man and give him a potential of the higher Ego, true self-reflection and personality, among other traits. Their dominant and defining roots are the reflections and guidance of the Spirits (which are manifestations of the outer Gods existing beyond any totality), however not all of them (including their souls) are actively Spirited, the remainder are just the echoes that perpetuate some of the potential as long as they are sustained.
These types never truly mix on the archetypal and entelechial level, even if it may appear so in the physical domain. In which case, only one of them predominates.
