What does hereditarian mean?
Hereditarian is a rare word used for a person who places primary explanatory weight on heredity—the transmission of characteristics from parents to offspring. As a noun, it designates an adherent of a hereditary theory, often in debates about biology, social class, or the relative roles of inheritance and environment. As an adjective, “hereditarian” describes theories, assumptions, or arguments that rest on heredity. The term is chiefly formal and historical rather than everyday, and it should not be confused with “hereditary,” the much more common adjective meaning passed down through a family. Because its modern context can include controversial racial and eugenic doctrines, careful writers usually identify whose hereditary theory is being discussed rather than using the label as a neutral description of scientific work. Even so, the word remains useful in intellectual history and in discussions of how biological inheritance has been interpreted and contested.
A person who holds that inherited characteristics are a primary determinant of development, behavior, social position, or another subject.

Hereditarian turns the principle of heredity into a label for its adherents—and recalls how ideas about inheritance have become entangled with scientific and social controversy.

Where does hereditarian come from?
The word was formed in English from hereditary, ultimately from Latin hereditarius, meaning “pertaining to inheritance,” with the suffix -arian, used for people who support or are associated with a doctrine. Its Latin base belongs to the family of heres, “heir,” and hereditas, “inheritance,” which also underlies English words such as heredity, inherit, and inheritor. The resulting term was used in English-language debates about hereditary explanations in biology and society.
