Title:"CRANIO-DENTAL EVIDENCE FOR INTER-POPULATION HOMOGENEITY IN THE ARCHAEOLOGICAL RECORD OF SOUTHERN AFRICAN IRON AGE PEOPLES."
Abstract:"The Iron Age of southernmost Africa began with the introduction of the 'Iron Age Package' and is associated with a migration of Bantu-speaking farmers in the first millennium AD from central and east Africa. The archaeological record shows that the Iron Age was dynamic in terms of trade, economic and population growth, and indicates further migration early in the second millennium from eastern Africa. While research suggests a certain degree of homogeneity among modern Bantu-speaking groups, little consideration has been given to variability within the Iron Age itself This study uses dental anthropology and 3D cranio-mandibular metrics to assess variability among farmer populations of the Iron Age. We show that there is considerable homogeneity between samples from the Early Iron Age (first millennium), Late Iron Age (second millennium) and more northerly samples from Zambia. This supports the conclusion of recent common ancestry (and common geographic origins), combined with a scenario that includes sustained admixture among groups over time. Additionally, an Early Iron Age sample from eastern Botswana, Toutswe, is equidistant from other Early Iron Age specimens and specimens from the Late Iron Age, while few differences are detected between samples east and west of the escarpment in the Late Iron Age.."

CRANIO-DENTAL EVIDENCE FOR INTER-POPULATION HOMOGENEITY IN THE ARCHAEOLOGICAL RECORD OF SOUTHERN AFRICAN IRON AGE PEOPLES
The Iron Age of southernmost Africa began with the introduction of the 'Iron Age Package' and is associated with a migration of Bantu-speaking farmers in the first millennium AD from central and east Africa. The archaeological record shows that the Iron Age was dynamic in terms of trade, economic and population growth, and indicates further migration early in the second millennium from eastern Africa. While research suggests a certain degree of homogeneity among modern Bantu-speaking groups, little consideration has been given to variability within the Iron Age itself This study uses dental anthropology and 3D cranio-mandibular metrics to assess variability among farmer populations of the Iron Age. We show that there is considerable homogeneity between samples from the Early Iron Age (first millennium), Late Iron Age (second millennium) and more northerly samples from Zambia.
