Mechanical Properties of Plant Underground Storage Organs and Implications for Dietary Models of Early Hominins [PDF]

, 2008
The diet of early human ancestors has received renewed theoretical interest since the discovery of elevated d13C values in the enamel of Australopithecus africanus and Paranthropus robustus.

A probable genetic origin for pitting enamel hypoplasia on the molars of Paranthropus robustus [PDF]

Journal of Human Evolution, 2019
We report the frequencies of linear enamel hypoplasia (LEH) and, specifically, pitting enamel hypoplasia (PEH) defects in the teeth of Paranthropus robustus, for comparison with four other South African hominin species and three extant nonhuman primate species.

Brain enlargement and dental reduction were not linked in hominin evolution [PDF]

, 2017
The large brain and small postcanine teeth of modern humans are among our most distinctive features, and trends in their evolution are well studied within the hominin clade.

Sexual Dimorphism in Homo erectus Inferred from 1.5 Ma Footprints Near Ileret, Kenya [PDF]

, 2019
Sexual dimorphism can be one of the most important indicators of social behavior in fossil species, but the effects of time averaging, geographic variation, and differential preservation can complicate attempts to determine this measure from preserved ...

Earliest hominin cancer: 1.7-million-year old osteosarcoma from Swartkrans Cave, South Africa [PDF]

, 2016
The reported incidence of neoplasia in the extinct human lineage is rare, with only a few confirmed cases of Middle or Later Pleistocene dates reported. It has generally been assumed that premodern incidence of neoplastic disease of any kind is rare and ...

The Influence of Fallback Foods on Great Ape Tooth Enamel [PDF]

, 2009
Lucas and colleagues recently proposed a model based on fracture and deformation concepts to describe how mammalian tooth enamel may be adapted to the mechanical demands of diet (Lucas et al.: Bioessays 30[2008] 374-385). Here we review the applicability

We the hunted

South African Journal of Science
Classic depictions of human evolutionary ecology cast Homo as predator and other hominins, including Paranthropus robustus, as prey. Such hypotheses rest on a small number of fossils that exhibit evidence of carnivore predation, including the iconic SK ...

Further morphological evidence on South African earliest Homo lower postcanine dentition: Enamel thickness and enamel dentine junction [PDF]

, 2016
The appearance of the earliest members of the genus Homo in South Africa represents a key event in human evolution. Although enamel thickness and enamel dentine junction (EDJ) morphology preserve important information about hominin systematics and ...

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 ...

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.
