For centuries, humanity has been fascinated by the idea of ​​perfection. In recent decades, the question has been raised regarding the perfect human being and whether scientists are capable of engineering and creating it. Attempts have been made in the past to engineer this “perfect” human, through eugenics and scientific racism, but so far these attempts have been ineffective. Only now, with modern technology, are scientists able to make more significant progress in altering the human genome to produce the desired characteristics of perfection. History has shown attempts to create a perfect and pure human race. Eugenics (the science of improving a human population through controlled or selective breeding to produce desirable hereditary characteristics) has played an important role in this, with government campaigns launched in countries such as Germany, South Africa, the United States, Australia and Sweden , to segregate the population and breed a pure and unmixed race. Adolf Hitler launched a similar campaign in Germany in the early 1900s. His idea of ​​the perfect human being was the Aryan “master race” – a population of white, blond-haired, blue-eyed Nordics. He wanted to raise this race of physically perfect humans, in his own words. With the idea that non-Aryans, especially Jews, were inferior to Aryans, he introduced the Nuremberg Laws, which classified the German population into Aryans and non-Aryans. Aryans. This chart shows how the Nuremberg Laws used a rudimentary form of genetics to determine whether a German was, in fact, German, Jewish, or Mischling ("mixed blood") by examining his or her ancestry and heritage. Once classified, the Aryan and non-Aryan races were kept strictly separate through laws such as the “Law for the Protection of German Blood...... middle of document......sed July 6, 2011. http: //www.holocaustresearchproject.org/holoprelude/pbgh.html• Nazi eugenics.
