Tracing Evolution Through Teeth: Dental Morphology of the Lagoa Santa Fossil Population
Kelsey Aaron
This study examines dental morphological variation among early South American populations, focusing on individuals from the Lagoa Santa region and coastal shellmound (sambaqui) populations in Brazil. Dental nonmetric traits were recorded using the Arizona State University Dental Anthropology System (ASUDAS), a standardized method for assessing crown and root morphology across populations (Qaqa et al., 2026). These traits are highly heritable and largely unaffected by environmental pressures, mak
