While I myself dont think the black people back then danced in a breakdancestyle or did any form of bboying at all it very much has similar movement points if you look at the Youtube videos A wild dancestyle 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
