Eugenics is a social movement that supports the supposed improvement of the human population via selective breeding and other means. It was originally developed by Francis Galton, a cousin of Charles Darwin, and based upon Darwin’s theory of evolution. The word eugenics literally means “good birth” and comes from a Greek word meaning “well-born, of good stock, of noble race.” The goal of eugenics is to make the world (or at least a country) a better place by guiding the course of human reproduction and “purifying” the gene pool.
