Final answer:
The American Anthropological Association issued a statement about race in 1998, emphasizing that race is a social construct rather than a scientifically valid concept. The statement outlined several points, but did not include the idea that racial divisions might lead to a separate species.
Step-by-step explanation:
The American Anthropological Association issued a statement about race in 1998, emphasizing that race is a social construct rather than a scientifically valid concept. The statement outlined several points, but one that was NOT included is option b: Although the continued sharing of genetic materials has maintained all humankind as a single species, some scientists suggest that current racial divisions in society that keep certain groups from interbreeding might lead to a true separate species.
According to biological anthropology, there is greater genetic variation within racial groups than between them (a). Physical variations in any given trait tend to occur gradually over geographic areas rather than abruptly (c). Race evolved as a world view, distorting ideas about human differences and group behavior (e). However, the idea that racial divisions in society might lead to a separate species is not among the points made by the statement.
