Introduction
Paranthropus is the robust hominin genus of Plio-Pleistocene Africa, defined by an extreme masticatory apparatus. It is a specialised side branch that shared the landscape with early Homo and left no descendants.
Body
1. Phylogenetic status: three species are generally recognised, P. aethiopicus (KNM-WT 17000, the Black Skull, West Turkana), P. boisei (OH 5, found by Mary Leakey at Olduvai in 1959) and P. robustus (TM 1517 from Kromdraai, described by Broom in 1938). The dispute is whether they form a clade united by shared megadonty, or whether East and South African robusticity is convergent, in which case they belong within Australopithecus. Descent from A. afarensis or from A. africanus is likewise unsettled; none is ancestral to Homo.
2. Characteristic features: sagittal crest for temporalis attachment, flaring zygomatic arches, a dished concave face, marked postorbital constriction and a large temporal fossa. Cranial capacity is only about 410 to 545 cc. Molars and premolars are enormously enlarged with very thick enamel, incisors and canines reduced, and the mandible deep and buttressed. The postcranium is australopith-like, fully bipedal, with a hand capable of a precision grip.
3. Distribution: East Africa from Omo, West Turkana, Koobi Fora, Olduvai, Peninj, Chesowanja and Konso; South Africa from Kromdraai, Swartkrans, Drimolen and Gondolin. The genus spans roughly 2.7 to 1.0 million years.
4. Lifeways: open woodland and savanna mosaic, generally near water. Long read from its jaws as a hard-object nutcracker feeder, it is now known from carbon isotopes that P. boisei ate overwhelmingly C4 grasses and sedges, while dental microwear shows P. robustus taking a mixed and seasonally variable diet. Bone tools from Swartkrans, polished by termite-digging, indicate tool use, and Oldowan artefacts occur in the same deposits, though attribution is disputed. Extinction near a million years is attributed to dietary specialisation under increasing aridity and to competition from Homo.
Conclusion
Paranthropus demonstrates that hominin evolution was a bush, not a ladder. Its megadont solution worked for over a million years and then failed.
