Ancient genomes from a rural site in Imperial Rome (1 st –3 rd cent. CE): a genetic junction in the Roman Empire

Abstract

ackground Rome became the prosperous Capital of the Roman Empire through the political and military conquests of neighbouring areas. People were able to move Romeward modifying the Rome area’s demographic structure. However, the genomic evidence for the population of one of the broadest Empires in antiquity has been sparse until recently. Aim The genomic analysis of people buried in Quarto Cappello del Prete (QCP) necropolis was carried out to help elucidate the genomic structure of Imperial Rome inhabitants. Subjects and methods We recruited twenty-five individuals from QCP for ancient DNA analysis through whole-genome sequencing. Multiple investigations were carried out to unveil the genetic components featuring in the studied samples and the community’s putative demographic structure. Results We generated reliable whole-genome data for 7 samples surviving quality controls. The distribution of Imperial Romans from QCP partly overlaps with present-day Southern Mediterranean and Southern-Near Eastern populations. Conclusion The genomic legacy with the south-eastern shores of the Mediterranean Sea and the Central and Western Northern-African coast funerary influence pave the way for considering people buried in QCP as resembling a Punic-derived human group.
