This is one of the lesser known things that I find quite interesting:
American blacks are actually like a sub-species of blacks. The conditions of the slave trade and transport to America across the Atlantic created a genetic bottleneck event based on which survived the journey and which didn't.
There are health issues which are much more prevalent in American blacks than European or African blacks. One of these is hypertension. The body factors that allowed them to survive the limited water rations they received during the voyage leads to hypertension in a "normal" environment. But for diabetes, asthma, and obesity... I don't know if they're related or not.
But beware: never ask yourself if there are any mental traits tied to the physical traits of the bottleneck, because that's "racist" and genetics doesn't work above the neck anyways :P Never mind that we've found that face shape is highly correlative to political stance....
And, of course, neither you nor I are or were slave traders, so we are not to blame.
