Intellectuals began expanding the "survival of the fittest" theory of evolution to social issues, and advocated that the "unfit" should be eliminated from mankind just as Darwin claimed they were naturally eliminated from the animal world. This led to the "eugenics" movement, which taught that those with the highest IQ or other advantageous traits should be favored, and those with low IQ or undesirable traits should be prevented from having children, or even eliminated themselves. These ideas became very popular in England and Germany. | Intellectuals began expanding the "survival of the fittest" theory of evolution to social issues, and advocated that the "unfit" should be eliminated from mankind just as Darwin claimed they were naturally eliminated from the animal world.
