†Paranthropus robustus The robust australopithecines, members of the extinct hominin genus Paranthropus (Greek para "beside", Greek anthropos "human"), were bipedal hominins that probably descended from the gracile australopithecine hominins (Australopithecus). All species of Paranthropus were bipedal, and many lived during a time when species of the genus Homo (which were possibly descended from Australopithecus), were prevalent. Paranthropus first appeared roughly 2.7 million years ago. Most species of Paranthropus had a brain about 40 percent of the size of modern man. There was some size variation between the different species of Paranthropus, but most stood roughly 1.3-1.4 m (4.26 to 4.59 feet) tall and were quite well muscled. Paranthropus is thought to have lived in wooded areas rather than the grasslands of the Australopithecus. The behavior of Paranthropus was quite different from that of the genus Homo, in that it was not as adaptable to its environment or as resourceful. Evidence of this exists in the form of its physiology which was specifically tailored to a diet of grubs and plants. This would have made it more reliant on favorable environmental conditions than members of the genus Homo, such as Homo habilis, which would eat a much wider variety of foods.
