How does the social construction of race challenge the idea that race is solely biological?

The social construction of race means that race is not just about biological differences, like skin color or hair type, but also about the way society views and categorizes people. This idea challenges the belief that race is solely biological because it shows that many of our ideas about race come from culture, history, and social interactions rather than genetics. For example, in different countries, people might classify race differently based on local customs and beliefs, which means that race can change depending on where you are. This suggests that what we think of as "race" is shaped by social factors, making it more of a social idea than a purely biological one. By understanding race this way, we can see how it affects people's lives and experiences in society.
