KIpura originates from angola just like Brazil, angola was under portuguese rule for 300+ years. The kipura of angola and the capoeira of brazil arent too much different the only difference is the capoeira style has more dancing than the kipura style because martial arts were outlawed by the portuguese so they disguised the martial art into a dance form. If you want to see true martial arts of brazilian origin there's this show called called Last Man Standing the very first episode deals with kalapalo wrestling 6 foreigners go to the kalapalo to train and compete in kalapalo wrestling.
I don't believe any modern authority on capoeira believes that the art is a simple transplant. Of course its African roots are recognized. Various African arts show some similarites. Nobody disputes that. But Capoeira developed in Brazil, from these various elements that were brought together there.
