Over time, the genus has changed from Zinjanthropus to Australopithecus to Paranthropus, but some researchers are still using genus: Australopithecus.. PHYLOGENY. Paranthropus (from Greek παρα, para "beside"; άνθρωπος, ánthropos "human") is a genus of extinct hominins.Also known as robust australopithecines, they were bipedal hominids that probably descended from the gracile australopithecine hominids (Australopithecus) 2.7 million years ago. Paranthropus robustus was the first of the robust Paranthropus australopithecines to be found (the other two robust australopithecines are Paranthropus aethiopicus and Paranthropus boisei).
