Race (human categorization):

"Race" is still sometimes used within forensic anthropology (when analyzing skeletal remains), biomedical research, and race-based medicine. Brace has criticized this, the practice of forensic anthropologists for using the controversial concept "race" out of convention when they in fact should be talking about regional ancestry. He argues that while forensic anthropologists can determine that a skeletal remain comes from a person with ancestors in a specific region of Africa, categorizing that skeletal as being "black" is a socially constructed category that is only meaningful in the particular context of the United States, and which is not itself scientifically valid.
