Which of the following best describes the historical definitions of racial categories in sociology?

Historical definitions of racial categories in sociology have often been based on physical characteristics, such as skin color, facial features, and hair type, as well as cultural and social factors. These categories were used to classify people into groups, often leading to stereotypes and discrimination. For example, in the past, people were often labeled as "black," "white," or "Asian" based solely on their appearance, which oversimplified the rich diversity within each group. Over time, sociologists have recognized that race is not just about biology but also about social constructs shaped by history and power dynamics. This understanding helps us see that racial categories can change and that they do not accurately reflect the complexity of individual identities.
