The concept of race as a categorization of anatomically modern humans (Homo sapiens) has an extensive history in Europe and the Americas. The contemporary word race itself is modern; historically it was used in the sense of "nation, ethnic group" during the 16th to 19th centuries. Race acquired its modern meaning in the field of physical anthropology through scientific racism starting in the 19th century. With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsolete. In 2019, the American Association of Biological Anthropologists stated: "The belief in 'races' as natural aspects of human biology, and the structures of inequality (racism) that emerge from such beliefs, are among the most damaging elements in the human experience both today and in the past."
The word "race", interpreted to mean an identifiable group of people who share a common descent, was introduced into English in about 1580, from the Old French (1512), from Italian . An earlier but etymologically distinct word for a similar concept was the Latin word meaning a group sharing qualities related to birth, descent, origin, race, stock, or family; this Latin word is cognate with the Greek words "genos", () meaning "race or kind", and "gonos", which has meanings related to "birth, offspring, stock ...".
In many ancient civilizations, individuals with widely varying physical appearances became full members of a society by growing up within that society or by adopting that society's cultural norms. (Snowden 1983; Lewis 1990)
Classical civilizations from Rome to China tended to invest the most importance in familial or tribal affiliation rather than an individual's physical appearance (Dikötter 1992; Goldenberg 2003). Societies still tended to equate physical characteristics, such as hair and eye colour, with psychological and moral qualities, usually assigning the highest qualities to their own people and lower qualities to the "Other", either lower classes or outsiders to their society.
