Endocast morphology of from the Dinaledi Chamber, South Africa.

Hominin cranial remains from the Dinaledi Chamber, South Africa, represent multiple individuals of the species This species exhibits a small endocranial volume comparable to , combined with several aspects of external cranial anatomy similar to larger-brained species of such as and Here, we describe the endocast anatomy of this recently discovered species. Despite the small size of the endocasts, they share several aspects of structure in common with other species of , not found in other hominins or great apes, notably in the organization of the inferior frontal and lateral orbital gyri. The presence of such structural innovations in a small-brained hominin may have relevance to behavioral evolution within the genus .
