On the relationship between maxillary molar root shape and jaw kinematics in Australopithecus africanus and Paranthropus robustus [PDF]

Royal Society Open Science, 2018
Plio-Pleistocene hominins from South Africa remain poorly understood. Here, we focus on how Australopithecus africanus and Paranthropus robustus exploited and—in part—partitioned their environment.

New fossils from Kromdraai and Drimolen, South Africa, and their distinctiveness among Paranthropus robustus [PDF]

Scientific Reports, 2022
Most fossil hominin species are sampled with spatial, temporal or anatomical biases that can hinder assessments of their paleodiversity, and may not yield genuine evolutionary signals.

Dietary Adaptation in Paranthropus robustus Postcanine Teeth. [PDF]

Am J Biol Anthropol
Upper premolar enamel thickness in Paranthropus robustus increased significantly over time, especially in the occlusal region. ABSTRACT Objectives Recent studies of Paranthropus robustus crania identified temporal trends in features associated with increased bite force production, coinciding with environmental shifts toward more arid conditions.

Environmental Context of Hominin Foot Evolution. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives This study investigates the environmental contexts that influenced the evolution of hominin foot morphology, focusing on when, where, and under what conditions key synapomorphies evolved. We test whether shifts in ecological conditions are associated with changes in locomotor function.

Cochlear shape distinguishes southern African early hominin taxa with unique auditory ecologies [PDF]

Scientific Reports, 2021
Insights into potential differences among the bony labyrinths of Plio-Pleistocene hominins may inform their evolutionary histories and sensory ecologies.

Complex and diverse patterns of neurocranial development in Australopithecus, Paranthropus and Homo [PDF]

Scientific Reports
Even though poorly understood, early ontogeny may have influenced the distinct morphologies and behaviors of Homo sapiens, fossil hominins and extant African apes.

Clades, Grades, and the Genus Problem: A Case for Revising Hominin Taxonomy. [PDF]

Am J Biol Anthropol
ABSTRACT Taxonomic practice in evolutionary biology increasingly prioritizes the recognition of monophyletic groups (clades), yet paleoanthropology still applies this principle inconsistently. Here, I outline these inconsistencies and broader challenges in hominin taxonomy and propose a potential solution.

Accessory cusp expression at the enamel-dentine junction of hominin mandibular molars [PDF]

PeerJ, 2021
Studies of hominin dental morphology frequently consider accessory cusps on the lower molars, in particular those on the distal margin of the tooth (C6 or distal accessory cusp) and the lingual margin of the tooth (C7 or lingual accessory cusp). They are

Comparative Morphometric Analysis of the Pelvis of LB 1 (Homo floresiensis). [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Although there has been copious research on the postcranial functional morphology of Homo floresiensis, there has been relatively little study of its pelvis and its implications for interpretations of H. floresiensis locomotion. Here we present the first comparative morphometric analysis of the pelvis of LB 1, the holotype of H ...

Inferences about fossil hominin locomotion through 3D morphometric analysis of wrist ligament insertion sites [PDF]

Scientific Reports
Understanding the evolution of wrist anatomy in fossil hominins is essential for reconstructing their locomotor behavior and manipulative capabilities. Traditionally, most studies have focused on bone morphology, overlooking the informative potential of ...
