i already told you there's a lot of over lap. Chiwetel Ejiofor, Idris Elba, and Nnamdi Asomugha could easily pass for typical aa. and many aa still have an ethnic african look to them.Some even think we speake the same langueg and all have that nigerian Accent.Disastar looms have you ever thought that since the african you subconsciencly picture in your brain are the ones easier to pick out.How about all the africans you passed and thought were AA? Ofcourse you can spot out the african who fits the description of a kunta kinte but even he was AA.Visit an african church or even african festivels in the states and see the diversity in real life not by pictures.Pictures have a tendecie to scream those are just the few or certain ones.Whenyou vist african gatherings you will understand the diversity in features,culture,dance,accents ect.I really do suggest you vist and be less ignorant.
but there's still an aa look. imo, the biggest difference is that on average aa are much better looking in the face and body, than WA in the states.
that's probably why someone who doesn't know africans very well might naturally assume precious was african.
