Brief Report: The Non-Metric Variation in the Dentition of the Earliest Americans (13.721 – 11.640 CYBP)

摘要

Dental non-metric data were described in a group of seven individuals of North and Central America. This report contributes to studies regarding the settlement of America by decribing the non-metric dental traits of the most ancient dentitions in the Americas. The sample consists of seven individuals from the Final Late Pleistocene (13.721-11.640 CYBP). Permanent dentitions from individuals between 5 and 35 years of age were scored for 13 dental traits based on the Arizona State University Dental Anthropology System (ASUDAS). These findings help us to have a comparable database with other groups and thus better understand the settlement process of human groups in the Americas and its relationship with migratory movements from Asia.
