Episode notes
Community Sparked The Project
- The San Luis de Cañete project began because the La Quebrada community wanted to understand the lives of their enslaved ancestors.
- Maria Nieves-Colón and collaborators joined after prior excavations revealed 245 individuals beneath the town plaza.
Children Show Evidence Of Intense Labor
- Osteological analysis showed many subadults and markers of nonspecific stress rather than chronic disease.
- This indicates children participated in intense labor and experienced early-life nutritional stress on the plantation.
Dental Modifications Signal African Origins
- Intentional dental modifications found in some skeletons match practices known from Africa and signal forced transatlantic displacement.
- Dental modification is a cultural marker that narrows identity but cannot pinpoint exact African origins alone.
