 Possibilities suggested have been to rename "Homo sapiens" to "Australopithecus sapiens" (or even "Pan sapiens"), or to move some "Australopithecus" species into new genera.Opinions differ as to whether the "Paranthropus" should be included within "Australopithecus", and "Paranthropus" is suggested along with "Homo" to have developed as part of a clade with "A. africanus" as its basal root.The members of "Paranthropus" appear to have a distinct robustness compared to the gracile australopiths, but it is unclear if this indicates all members stemmed from a common ancestor or independently evolved similar traits from occupying a similar niche.
