Summary

This is an abstract from the "“The South Also Exists”: The Current State of Prehistoric Archaeology in Brazil: Dialogues across Different Theoretical Approaches and Research Agendas" session, at the 89th annual meeting of the Society for American Archaeology.

Biodistance studies (craniometrics and aDNA) have been very useful tools to unravel the biological diversity of human populations in the past. In this abstract, we present biodistance analyses based on cranial measurements in order to further understand the relationship between hunter-gatherer groups that inhabited the Ribeira de Iguape Valley (São Paulo and Paraná, Brazil) and other Brazilian groups. These populations from Ribeira do Iguape are associated with the building of riverine shell mounds, using terrestrial gastropod shells during the Holocene. Our results point to a great morphological diversity in the Ribeira de Iguape region from the Early to the Late Holocene. The early Holocene individual shows a very distinct cranial morphology when compared to the middle and late Holocene groups, while these later populations show affinities to individuals associated to the middle and late Holocene coastal shell-mound occupation. We discuss these results, including new data on the paleogenomics of individuals from the Ribeira do Iguape region and the coastal groups.
