Paranthropus robustus is a small-brained extinct hominin from South Africa characterized by derived, robust craniodental morphology. The most complete known skull of this species is DNH 7 from Drimolen Main Quarry, which differs from P. robustus specimens recovered elsewhere in ways attributed to sexual dimorphism. Here, we describe a new fossil specimen from Drimolen Main Quarry, dated from approximately 2.04–1.95 million years ago, that challenges this view. DNH 155 is a well-preserved adult… 
Cochlear shape distinguishes southern African early hominin taxa with unique auditory ecologies
Diffeomorphometry reveals size-independent differences in cochlear shape between Paranthropus robustus and Australopithecus africanus that exceed those among modern humans and the African apes and suggests that sound perception shaped distinct ecological adaptations among southern African early hominins.
Divergence-time estimates for hominins provide insight into encephalization and body mass trends in human evolution.
This work applies a total evidence dating approach to a hominin phylogeny to estimate divergence times under different topological hypotheses and shows that the origin of the genus Homo probably occurred between 4.30 and 2.56 million years ago.
Molar biomechanical function in South African hominins Australopithecus africanus and Paranthropus robustus
Diet is a driving force in human evolution. Two species of Plio-Pleistocene hominins, Paranthropus robustus and Australopithecus africanus, have derived craniomandibular and dental morphologies which
The partial skeleton StW 431 from Sterkfontein - Is it time to rethink the Plio-Pleistocene hominin diversity in South Africa?
Questions are raised whether it is justified to subsume hominins from Taung, Makapansgat and Sterkfontein (and Gladysvale) within a single taxon and given the wealth of fossil material and analytical techniques now available, it is called for a re-evaluation of the taxonomy of South African Plio-Pleistocenehominins.
Mechanical compensation in the evolution of the early hominin feeding apparatus
Australopiths, a group of hominins from the Plio-Pleistocene of Africa, are characterized by derived traits in their crania hypothesized to strengthen the facial skeleton against feeding loads and
Microhabitat Variability in Human Evolution
Climate variability and hominin evolution are inextricably linked. Yet, hypotheses examining the impact of large-scale climate shifts on hominin landscape ecology are often constrained by proxy data

Cranial variation in South African specimens of Paranthropus robustus illustrate temporal changes that suggest how the morphology of this hominin fossil species related to its palaeoenvironment and
Ground‐penetrating radar analysis of the Drimolen early Pleistocene fossil‐bearing palaeocave, South Africa
The cave systems of the Malmani Dolomite, Gauteng, South Africa, have over the decades yielded numerous specimens of Pliocene to early Pleistocene hominin fossils which are critical for our


The Homo floresiensis cranium (LB1): Size, scaling, and early Homo affinities
The results are consistent with hypotheses that suggest the Liang Bua specimens represent a diminutive population closely related to either early H. erectus s.
A Complete Skull from Dmanisi, Georgia, and the Evolutionary Biology of Early Homo
The Dmanisi sample, which now comprises five crania, provides direct evidence for wide morphological variation within and among early Homo paleodemes, implying the existence of a single evolving lineage of early Homo, with phylogeographic continuity across continents.
Contemporaneity of Australopithecus, Paranthropus, and early Homo erectus in South Africa
The age confirms that species of Australopithecus, Paranthropus, and early Homo overlapped in the karst of South Africa ∼2 million years ago and establishes these fossils as the oldest definitive specimens of their respective species ever discovered.
A 3.8-million-year-old hominin cranium from Woranso-Mille, Ethiopia
A nearly complete hominin cranium from Woranso-Mille (Ethiopia) that is date to 3.8 million years ago is described, providing the first glimpse of the entire craniofacial morphology of the earliest known members of the genus Australopithecus.
Australopithecus sediba: A New Species of Homo-Like Australopith from South Africa
Combined craniodental and postcranial evidence demonstrates that this new species of Australopithecus shares more derived features with early Homo than any other australopith species and thus might help reveal the ancestor of that genus.
Reconstructed Homo habilis type OH 7 suggests deep-rooted species diversity in early Homo
A virtual reconstruction of the OH 7 mandible is presented, finding that this shape variability is not consistent with a single species of early Homo, and raising questions about the H. habilis hypodigm.
