Quick Summary

Eugenics is the practice of controlling reproduction to improve the genetic makeup of future generations. Coined in 1883 by Francis Galton, it was influenced by Charles Darwin's theory of natural selection and the concept of "survival of the fittest".1

Positive eugenics aimed to encourage reproduction among those deemed to have desirable traits, while negative eugenics sought to prevent reproduction among those considered to have undesirable traits.1

While eugenics gained scientific and political support in the early 1900s, it ultimately failed as a science by the 1930s and 1940s. This decline was due to heavy criticism of its assumptions and its horrific misuse by Nazi Germany to justify genocide. Modern genetics has advanced significantly, but ethical considerations surrounding genetic technologies remain a subject of discussion.12
