natural populations, and in facilitating adaptation to new environmental conditions and challenges. However, both population
genetics and the American conservation movement have their roots in the human eugenics movement of a century ago,
which viewed genetic diversity among human populations as grounds for discrimination and prejudice.\footnote{Fisher,

unfortunate part of the history of both population genetics and conservation, and denounce how it has been used to suppress
and disadvantage people.
Many of the early statistical methods that still underlie genetic analysis were developed by devout eugenicists. Francis
Galton, a cousin of Charles Darwin, coined the term eugenics in 1883 (Galton 1883, p. 24). Simply put, the field of eugenics
viewed human traits as the product of genes, some trait variants more valuable than others, and therefore some human races
as better than others (Rohlfs 2020).\footnote{US President Theodore Roosevelt and his conservation chief
