Eugenics is derived from the Greek meaning “well-born”. It is the science of improving a population by controlled breeding to increase the occurrence of desirable heritable characteristics. Because of this, it can be closely linked to Social Darwinism, the application of natural selection to human society. Nowadays, eugenics is a term used almost exclusively with regard to Nazi Germany, however...
