The terms Mongoloid, Caucasoid, and Negroid used by Rushton (2000) was in wide use in mainstream literature until the 1990s at least, e.g. by Luigi Luca Cavalli-Sforza. Since the 2000s, these terms have been deprecated in by some authorities. For example, the recommended Medical Subject Headings as of 2004 was "Oriental Continental Ancestry Group, "African Continental Ancestry Group" and "European Continental Ancestry Group" for "Mongoloid", "Caucasoid" and "Negroid", respectively. The MeSH descriptor Racial Stocks, and its four children (Australoid Race, Caucasoid Race, Mongoloid Race, and Negroid Race) have been deleted from MeSH in 2004 along with Blacks and Whites. Race and ethnicity have been used as categories in biomedical research and clinical medicine. Recent genetic research indicates that the degree of genetic heterogeneity within groups and homogeneity across groups make race per se a less compelling predictor.
