Results show that significant directional changes do occur in the A. afarensis mandibles and teeth, and in these elements, the species is not static, even though other factors, such as sexual dimorphism, may also play a part.
Sexual dimorphism in the face of Australopithecus africanus.

Resampling methodology (bootstrapping) is used here to establish that A. africanus has a greater craniofacial size range than chimpanzees or modern humans, a range which is best attributed to a moderately high degree of sexual dimorphism.

Three-dimensional landmark data from the hominoid temporal bone effectively quantify the shape of a complex element of the skull and reveal the potential for geometric morphometric analysis to shed light on phylogenetic relationships.

Extended male development in a hominin species, Paranthropus robustus, is described, suggesting that male reproductive strategy focused on monopolizing groups of females, in a manner similar to that of silverback gorillas.

Quantifying temporal bone morphology of great apes and humans: an approach using geometric morphometrics

3D geometric morphometrics techniques are used to quantify differences among humans and great apes and discuss the results in a phylogenetic context, contradicting depictions of African apes as a single morphotype.
A large male hominin cranium from Sterkfontein, South Africa, and the status of Australopithecus africanus.

In several areas-the distinct anterior pillar, the straight inferior border of the zygoma, the pattern of cresting on the naso-alveolar clivus, the basal aspect of the temporal bone-Stw 505 closely matches the morphology of specimens of Australopithecus africanus and is distinct from other hominins.
