Why isn't race biological?

Race is not biological because genetic variation within so-called racial groups is often greater than that between them, indicating that human beings share more genetic similarities than differences. The concept of race is a social construct that categorizes individuals based on physical characteristics, such as skin color, rather than on distinct biological or genetic differences. Additionally, the traits used to define races are influenced by environmental factors and cultural practices, further underscoring that race lacks a clear biological basis. Ultimately, the idea of race reflects social, historical, and political contexts rather than scientific distinctions.
