A groundbreaking genomic study published this month has analyzed the DNA of several individuals found in 2,500-year-old burials near Madurai. The results show a high degree of genetic continuity between these Iron Age inhabitants and the current populations of the region, specifically those historically associated with the Sangam literature traditions.
The study provides scientific weight to the historical claim that the culture described in the Sangam poems is an indigenous development with thousands of years of local roots. This research helps clarify the complex peopling of South India and confirms the stability of the regional genetic landscape over the last three millennia.
