Distinct mandibular premolar crown morphology in Homo naledi and its implications for the evolution of Homo species in southern Africa

Using geometric morphometrics, the morphology of the mandibular premolars of the species at the enamel-dentine junction is assessed and it is found that the H. naledi premolars consistently display a suite of traits that distinguish them from known hominin groups.

Comparative morphometric analyses of the deciduous molars of Homo naledi from the Dinaledi Chamber, South Africa.

This research provides another perspective on the morphology of, and variation within, H. naledi and suggests that the crown shapes and relative cusp areas of mandibular molars are more diagnostic than the maxillary molars.

Relative tooth size, Bayesian inference, and Homo naledi.

The present results place H. naledi as a sister taxon to H. habilis, based on a symplesiomorphic pattern of relative tooth size, within a clade comprising all Homo species, but it shares some characteristics with australopiths and, particularly, early Homo.

Tooth size apportionment, Bayesian inference, and the phylogeny of Homo naledi

H. naledi is placed as a sister taxon to H. habilis, nested within a clade comprising australopiths and early Homo dating 3.3 Ma to ∼800 ka, distinct from younger H. erectus through H. sapiens.

A novel system for classifying tooth root phenotypes

Using CT scans, a method of classification that captures external and internal root morphology in a way that is intuitive, reproducible, and defines the human phenotypic set is developed and provides a robust definition of modern human tooth root phenotypesic diversity.

Annual assessments of the root morphology of the 'robust' australopithecines from Swartkrans suggest that the premolar root form of Australopithecus (Paranthropus) robustus is not obviously intermediate between the presumed ancestral condition, and the 'molarised' mandibular premolars root systems of Australo-Pleistocene hominids.
