Forgive me, this may be a simple question. It's 4am, can't sleep and a million things have already raced through my mind. I need an answer to this and Google is flooding me with tons of information/articles that aren't getting down to the bottom line. Atleast I can't find the bottom line myself. So over to you MNers. Help me when you're up and can be arsed. Thanks 
If Black people = African descent (as many forms state and a lot of people have said), I take this to mean Black people have African ancestry, regardless if it's dating 1 generation or 400 generations ago. So what is white descent? Where have White people descended from?
