Species of "Paranthropus" had smaller braincases than "Homo", yet they had significantly larger braincases than "Australopithecus". Paranthropus is associated with stone tools both in southern and eastern Africa, although there is considerable debate whether they were made and utilized by these robust australopithecines. Most believe that early "Homo" was the tool maker. Most "Paranthropus" species almost certainly did not have language or to have controlled fire, although they are directly associated with the latter at Swartkrans, South Africa.
