The question has often been asked: Between culture and biology, what precedes what? Most scholars agree that culture does.
Whites do not have a long nose because it biologically predicted the cold weather in the Northern Hemisphere. That would have been as impossible as a cow’s alimentary canal foretelling the difficulty of digesting grass, and therefore dividing itself into four stomachs in anticipation of the task. Both cases of organ specialisation are a result of gradual adaptation (culture) which spans millions of years.
