The theory of evolution is based on individuals acquiring unique traits that enable those possessing the new traits to better survive adverse conditions compared to those who don’t possess them. Superior individuals will be more likely to survive and pass on these traits to their offspring so such traits will increase in number, while the ‘weaker’ individuals will eventually die off. If every member of a species were fully equal, natural selection would have nothing to select from, and evolution would cease for that species.
These differences gradually produce new groups, some of which have an advantage in terms of survival. These new groups became the superior, or the more evolved races. When a trait eventually spreads throughout the entire race because of the survival advantage it confers on those that possess it, a higher, more evolved form of animal will result. Hitler and the Nazi party claimed that one of their major goals was to apply this accepted ‘science’ to society. And ‘the core idea of Darwinism was not evolution, but selection. Evolution … describes the results of selection’. Hitler stressed that to produce a better society ‘we [the Nazis] must understand, and cooperate with science’.
As the one race above all others, Aryans believed that their evolutionary superiority gave them not only the right, but the duty to subjugate all other peoples.
Through study from book and through scientific views, Germans began to see what made other races inferior and began to see themselves and the superior race among all. Hitler took complete power of the German Nation as a dictator and spent a few years preparing for war to targeting inferior races. Hitler saw himself as responsible to create a Superior Race and as having the rights to do whatever he could to complete this objective.
Hitler believed humans were animals to whom the genetics laws, learned from livestock breeding, could be applied. The Nazis believed that instead of permitting natural forces and chance to control evolution, they must direct the process to advance the human race. The first step to achieve this goal was to isolate the ‘inferior races’ in order to prevent them from further contaminating the ‘Aryan’ gene pool. The widespread public support for this policy was a result of the belief, common in the educated classes, in the conclusion that certain races were genetically inferior as was scientifically ‘proven’ by Darwinism. The Nazis believed that they were simply applying facts, proven by science, to produce a superior race of humans as part of their plan for a better world.
According to Nazism, it is an obvious mistake to permit or encourage multilingualism and multiculturalism within a nation. Fundamental to the Nazi goal was the unification of all German-speaking peoples, "unjustly" divided into different Nation States. Hitler claimed that nations that could not defend their territory did not deserve it. Slave races, he thought of as less-worthy to exist than "master races." In particular, if a master race should require room to live, he thought such a race should have the right to displace the inferior indigenous races. Hitler draws parallels between Lebensraum and the American ethnic cleansing and relocation policies towards the Native Americans, which he saw as key to the success of the US.
"Races without homelands," Hitler claimed, were "parasitic races," and the richer the members of a "parasitic race" are, the more "virulent" the parasitism was thought to be. A "master race" could therefore, according to the Nazi doctrine, easily strengthen itself by eliminating "parasitic races" from its homeland. This was the given rationalization for the
