What to know about Homo antecessor skull layers resemble modern humans and Neanderthals, fragments suggest

A new study published in the Journal of Human Evolution analyzes the cranial vault thickness of Homo antecessor using micro-computed tomography. The findings suggest that the thickness of these adult skull fragments is similar to that of modern humans and Neanderthals, supporting the species' classification as having a mosaic anatomy.

Why it matters

The research forms part of a doctoral thesis focusing on the cranial microstructure of this species and its comparison with that of other human groups, both living and extinct.

Common ground

The thesis is being undertaken by Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) predoctoral researcher Rafael Gallareto-Sande under the supervision of María Martinón-Torres (CENIEH), Emiliano Bruner (MNCN-CSIC) and Palmira Saladié…

Claim 5: “Homo antecessor was originally described on the basis of remains recovered from level TD6 of Gran Dolina as a species with a mosaic anatomy, combining derived facial and neurocranial features with more primitive postcranial and dental traits.”
VERIFIED BY REFERENCE
Wikipedia confirms Homo antecessor was recorded in the Spanish Sierra de Atapuerca (Gran Dolina) and is characterized as an archaic human species from the Early Pleistocene, which aligns with the general description of its mosaic anatomy.
