Problems with paranthropus [PDF]

, 2023
Carbon isotopic analysis has been challenging our ideas about hominin diet for nearly 30 years. The first study in 1994 revealed that Paranthropus robustus from South Africa consumed principally C3 foods (e.g., tree fruits and leaves) but also about 25 ...

Further assessment of a ~2-million-year-old hominin pelvis (DNH 43) from Drimolen Main Quarry, South Africa

South African Journal of Science
The palaeocave site of Drimolen Main Quarry (DMQ) in Gauteng Province, South Africa, has produced fossil hominin material dating to 2.04–1.95 Ma, including craniodental remains attributed to Paranthropus robustus and the earliest specimen of Homo ...

Cortical bone distribution in the femoral neck of Paranthropus robustus

, 2019
Studies of the australopith (Australopithecus and Paranthropus) proximal femur have increasingly integrated information from the local arrangement of the cortical and cancellous bone to allow functional-biomechanical inferences on the locomotor ...

Dental ontogeny in pliocene and early pleistocene hominins.

PLoS ONE, 2015
Until recently, our understanding of the evolution of human growth and development derived from studies of fossil juveniles that employed extant populations for both age determination and comparison.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

The Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Endostructural assessment of a hominin maxillary molar (StW 669) from Milner Hall, Sterkfontein, South Africa

South African Journal of Science, 2019
The site of the Sterkfontein Caves, South Africa, is one of the richest early hominin fossil-bearing sites in Africa. Recent excavations in the Milner Hall locality have contributed to the discovery of new hominin specimens, including StW 669, a right ...

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Hominin dispersals: causes, conditions, and outcomes Dispersions des hominines : causes, conditions et issues

Journal of the Royal Anthropological Institute, EarlyView.
The ‘Out of Africa’ model that has dominated palaeoanthropology for nearly three decades was originally based on five elements: a recent ancestry to human populations; an African origin for the ancestral population; limited or no gene flow among archaic hominins and no admixture between modern humans and Neanderthals; a marked difference between the ...

New hominin cranial and mandibular remains from Drimolen Main Quarry, South Africa

Annals of Human Biology
Background To date, the only specimens to have been comprehensively described from Drimolen Main Quarry (DMQ) are dental elements, well preserved crania (DNH 7, DNH 134, DNH 152, DNH 155), and 29 post-cranial elements.

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...
