New hominin fossils from Kanapoi, Kenya, and the mosaic evolution of canine teeth in early hominins

South African Journal of Science, 2012
Whilst reduced size, altered shape and diminished sexual dimorphism of the canine-premolar complex are diagnostic features of the hominin clade, little is known about the rate and timing of changes in canine size and shape in early hominins. The earliest

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.

Enamel Prism Angle Variation and Hard‐Object Feeding in Cercopithecoids With Known Diets

American Journal of Biological Anthropology, Volume 188, Issue 3, November 2025.
Left: Cercocebus atys specimen 16–9 third molar showing Phase II enamel prism angle (angle between prism path and wear facet) and wear angle (angle between wear facet and enamel dentin junction (EDJ)). Scatterplot of prism vs. wear angles for the Phase II wear facet. Note the higher angles for Cercocebus.

Interpreting sulci on hominin endocasts: Old hypotheses and new findings

Frontiers in Human Neuroscience, 2014
Paleoneurologists analyze internal casts (endocasts) of fossilized braincases, which provide information about the size, shape and, to a limited degree, sulcal patterns reproduced from impressions left by the surface of the brain.

Statistical shape modelling as a novel reconstruction tool in palaeoanthropology: A case study on fossil pelves

Methods in Ecology and Evolution, Volume 16, Issue 11, Page 2569-2584, November 2025.
Abstract Reconstructing incomplete anatomical regions of extinct taxa is critical for understanding their ecological and evolutionary context, including their migration patterns, reproductive strategies and environmental adaptations. In hominins, the pelvis can be particularly challenging to reconstruct because crushing and fragmentation during ...

Australopithecus robustus societies – one-male or multimale?

South African Journal of Science, 2016
Determining the sex of individual specimens is important in estimating the degree of sexual dimorphism. Sexual dimorphism, in turn, provides clues for reconstructing the social organisation and mating systems of extinct species.

Early humans and the balance of power: Homo habilis as prey

Annals of the New York Academy of Sciences, Volume 1553, Issue 1, Page 140-157, November 2025.
The traditional view regarding Homo habilis as the primary agent in stone‐tool making and animal butchery has long shaped our understanding of human evolution. Recent advances in artificial intelligence (AI) methods have provided unprecedented insights into carnivore–hominin interactions through the analysis of bone surface modifications (BSMs).
