Seeing distinct groups where there are none: spurious patterns from between-group PCA
Using sampling experiments, we found that, when there are fewer groups than variables,
between-groups PCA (bgPCA) may suggest surprisingly distinct differences among groups …

An updated analysis of hominin phylogeny with an emphasis on re-evaluating the phylogenetic relationships of Australopithecus sediba
The discovery and description of Australopithecus sediba has reignited the debate over the
evolutionary history of the australopiths and the genus Homo. It has been suggested that A …

Efficacy of diffeomorphic surface matching and 3D geometric morphometrics for taxonomic discrimination of Early Pleistocene hominin mandibular molars
Morphometric assessments of the dentition have played significant roles in hypotheses
relating to taxonomic diversity among extinct hominins. In this regard, emphasis has been …

Reconstruction, endocranial form and taxonomic affinity of the early Homo calvaria KNM-ER 42700
When first described, the small calvaria KNM-ER 42700 from Ileret, Kenya, was considered
a late juvenile or young adult and assigned to Homo erectus. However, this species …

Using the covariation of extant hominoid upper and lower jaws to predict dental arcades of extinct hominins
Upper and lower jaws are well represented in the fossil record of mammals and are
frequently used to diagnose species. Some hominin species are only known by either their …
