The objective of this study was to examine whether the premolars and molars found at Sterkfontein Sts Mbr. 4 and StW Mbr. 5 are morphometrically similar to the degree that all individuals could belong to the same species, A. africanus. Mesial-distal (MD) and buccal-lingual (BL) measurements were obtained from maxillary premolars (P³ and P⁴) and molars (M¹, M², and M³) of Homo, Pan, and Gorilla, and compared to their counterparts attributed to A. africanus from Sterkfontein. Specimen samples were statistically analyzed using univariate and multivariate analyses. The results support the acceptance of the null hypothesis, indicating that the dental remains from Sts Mbr. 4 and StW Mbr 5 are from the same species.
