Genomic Investigation of Archaeological Remains: Genomics Unveils Insights into Human Evolution and Ancient Societal Practices

Genomic research on archaeological remains has opened up infinite possibilities, allowing us not only to understand the vicissitudes of human evolution but also to help answer questions regarding various aspects of our ancestors' socio-cultural attitudes. A British research team has investigated some of the oldest known cases involving contrasting genetic disorders affecting the skeletons, which include the syndromes of Turner, Jacob, and Klinefelter, as well as a trisomy in chromosome 21, known as Down syndrome. This study reveals that these conditions are a result of aneuploidy, or the presence of an extra chromosome, which can lead to developmental changes, such as delayed growth, variations in stature, etc. The individuals with these syndromes whose remains were studied ranged from 18 to 22 years old, with some living during the Iron Age (2.5 thousand years ago) to the Modern Age (250 years ago). The details of the study were published in the journal Communications Biology.
