Human remains were unearthed during a construction project in Charleston, S.C., in 2013. Genetic research revealed they were enslaved people from diverse parts of Africa.
published three years ago presented detailed studies of the bones and an analysis of their mitochondrial DNA, which is inherited from mothers. That work
The newest results confirm those findings and expand on them. Mapping their genomes gave researchers more insight into their ancestry and helped answer the question of whether they were related to one another. They weren’t, with the exception of Isi and Welela. The 36 people appear to have been buried as they died, rather than in family groups or in a mass grave.
Raquel Fleskes, an anthropological geneticist at the University of Connecticut, wore a GoPro camera to document the process of extracting DNA from the bone samples, to share the experience with the community. Anne Stone, an anthropological geneticist at Arizona State University who edited the paper for PNAS but was not involved in the research, said that the genetic study adds a dimension of knowledge that could only be hinted at by detailed study of the bones.
