Indisputably, Boas is the father of four-field American anthropology. His book Race, Language, and Culture (1940/1966) is a collection of essays on those key topics. Boas contributed to cultural, biological, and linguistic anthropology. His biological studies of European immigrants to the United States revealed and measured phenotypical plasticity. The children of immigrants differed physically from their parents not because of genetic change but because they had grown up ir a different environment. Boas showed that human biology was plastic. It could be changed by the environment, including cultural forces. Boas and his students worked hard to demonstrate that biology (including race) did not determine culture. In an important book, Ruth Benedict (1940) stressed the idea that people of many races have contributed to major historical advances and that civilization is the achievement of no single race.
