How have historical definitions of racial categories, like 'Caucasian', influenced societal perceptions of race today?

Historical definitions of racial categories, such as 'Caucasian', have shaped how society views race today by creating fixed ideas about different groups of people. For example, the term 'Caucasian' was originally used to describe people from Europe and parts of Asia, but over time, it has been applied more broadly to include many white-skinned individuals. This broad application can lead to misunderstandings, as it ignores the diversity within these groups and promotes a simplistic view of race. As a result, people may still rely on outdated definitions that do not reflect the complexity of human identity, influencing attitudes and behaviors in areas like employment, education, and social interactions. Understanding these historical definitions helps us see why stereotypes persist and why it’s important to approach race with a more nuanced perspective today.
