Question

1. why is race not a real biological distinction?

Explanation:

Genetically, human populations are highly similar. There is more genetic variation within so - called "racial" groups than between them. Traits associated with race like skin color are the result of adaptation to local environments and do not represent distinct biological boundaries.

Answer:

Race is not a real biological distinction because there is greater genetic variation within racial groups than between them, and racial traits are mainly environmental adaptations rather than clear - cut biological differences.
