Interpreting sulci on hominin endocasts: Old hypotheses and new findings
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.

ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Australopithecus from Sterkfontein Caves, South Africa
Since the discovery by Robert Broom of the first adult Australopithecus at Sterkfontein in 1936, a large quantity of fossil remains of this genus, consisting of crania, teeth and postcranial bones, has been excavated from those cave infills.

Australopithecus robustus societies – one-male or multimale?
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.

Opaque Social Instruments: A Cultural Evolutionary Approach to Pleistocene Symbolic Artifacts
ABSTRACT Prehistoric “symbolic” artifacts remain incompletely explained by semiotic models, which emphasize representational meaning but offer limited insight into how such materials emerged and spread across Pleistocene populations. This article develops a cultural evolutionary framework that reconceives early ornaments, pigments, figurines, and ...

Thoracic vertebral count and thoracolumbar transition in Australopithecus afarensis [PDF]
The evolution of the human pattern of axial segmentation has been the focus of considerable discussion in paleoanthropology. Although several complete lumbar vertebral columns are known for early hominins, to date, no complete cervical or thoracic series

Palaeomagnetic analysis indicates that Haasgat, a fossil-bearing palaeocave in the Gauteng Province of South Africa, is dominated by reversed magnetic polarity in its oldest, deepest layers and normal polarity in the younger layers.

Special issue: Australopithecus sediba --- The Hand of Australopithecus sediba
Here we describe the functional morphology of the Australopithecus sediba hand, including the almost complete hand of the presumed female Malapa Hominin (MH) 2 skeleton and a single, juvenile metacarpal from the pre-sumed male MH1 skeleton.

Morphological evolution of the hominid brain
A comparative analysis of the brain surfaces and endocasts of 35 hominid specimens including 24 operational taxonomic units was performed with the aim to search for morphological transformations of the brain surface that occurred over time ...

Morphological affinities of Homo naledi with other Plio-Pleistocene hominins: a phenetic approach
Recent fossil material found in Dinaledi Chamber, South Africa, was initially described as a new species of genus Homo, namely Homo naledi. The original study of this new material has pointed to a close proximity with Homo erectus.
