while i myself don't think the black people back then danced in a breakdance style or did any form of bboying at all it very much has similar movement points if you look at the youtube videos a wild dance style element for instance and moves that are not too easy for the untrained one even a bit acrobatic so here i agree that both dance styles have an element in common i am not sure if this is enough to warrant a historical connection but it could be that the earlier dance style influenced the later one
