DNA analysis offers new insights into A Yale-led research team has conducted the first genome-wide study of retainers who lived and worked at Machu Picchu.
The genomic data, described in a new study in Science Advances, is the first investigation of the genomic diversity of individuals buried at Machu Picchu and adjacent places around Cusco, the Inca capital. It builds upon previous archeological and bio-archaeological research, including a 2021 Yale-led study which found that Machu Picchu (AD 1420-1530) is older than was previously believed.
"The DNA analysis not only confirms the historical accounts that retainers were drawn from many different ethnic groups under Inca control, but it also demonstrates a much greater diversity of origins than had been suspected with individuals being brought from the entire empire," said archaeologist Richard Burger, the Charles J. MacCurdy Professor of Anthropology in Yale's Faculty of Arts and Sciences and lead researcher for the Machu Picchu project.
