Actually, historically speaking, the African American professional classes used to distinguish themselves from the rest of the black populace by their features (skin color, hair grade, etc.) The more sharper (western/european) your features were, the more "desirable" you were considered. And they would choose their mating partners based off of these characteristics. So you had all of these "desirable" people mating generation after generation to keep those desirable features. There was a saying that, the higher you went up in status in the black community, the more attractive the people got. Hence, there is a reason why Howard University is known for all of it's attractive women as opposed to, let's say, Lane College. It's a different demographic. I'm not hipped to all of the black history in Philly but I would assume, in general, the black community would look a bit different, than neighboring DC, which due to Howard and the government, had a sizeable black professional middle class population.
