The classification of individuals as 'Caucasian' has had significant implications for societal structures and identity. What underlying factor contributed to the broad and often inaccurate grouping of diverse ethnicities under this racial category?

The classification of individuals as 'Caucasian' stems from historical ideas about race that oversimplified human diversity. In the 18th and 19th centuries, scientists and scholars tried to categorize people based on physical traits, often focusing on skin color and facial features. This approach ignored the rich cultural backgrounds and histories of different groups, leading to a broad label that included many diverse ethnicities. For example, people from Europe, the Middle East, and parts of North Africa were all grouped as Caucasian, even though they have distinct cultures and identities. This oversimplification has had lasting effects, influencing social structures and how people see themselves and others in society.
