Yeah, the DNA project is really interesting...I think it's called Genographic and anybody can go to their website and do it, if you want to pay $100! I'd like to do my dad's side too, but haven't forked out the dough.

My point with explaining my history for the past 50,000 years (haha) is to ask at what point did my ancestors stop being "black" and become "white"? I think this shows how the categories of race are not biologically definable, which isn't to say that race and ethnicity aren't culturally and socially important, which has had both good and bad consequences!
