Eugenics is a largely discredited set of beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have attempted to alter the frequency of various human phenotypes by inhibiting the fertility of those considered inferior, often through forced sterilization, or promoting that of those considered superior.
The term "eugenics" predates genetics; "eugenics" was coined by Francis Galton in 1883, whereas "genetics" was proposed as a scientific discipline in 1906.
The contemporary history of eugenics began in the late 19th century, following the emergence of the theory of evolution and natural selection. A popular eugenics movement emerged in the United Kingdom, and spread to most European countries (e.g., Sweden and Germany), and many other countries, including the United States, Canada, and Australia.
Historically, the idea of eugenics has been used to argue for a broad array of practices ranging from prenatal care for mothers deemed genetically desirable to the forced sterilisation and murder of those deemed unfit. To population geneticists, the term has included the avoidance of inbreeding without altering allele frequencies; for example, British-Indian scientist J. B. S. Haldane wrote in 1940 that "the motor bus, by breaking up inbred village communities, was a powerful eugenic agent." Debate as to what qualifies as eugenics continues today.
A progressive social movement promoting eugenics had originated in the 19th century, with diverse support, but by the mid 20th century the term was closely associated with scientific racism and authoritarian coercion. With modern medical genetics, genetic testing and counselling have become common, and new or liberal eugenics rejects coercive programmes in favour of individual parental choice.
