WebRobust Australopithecine vs. Paranthropus There are a number of physical differences between "robust" Australopithecines and earlier, more gracile Australopithecines. Due to these differences, modern scholars disagree about whether to put these species into their own genus, Paranthropus, or keep them in the genus Australopithecus.
