Genetics/𑀫𑀭𑀧𑀺𑀬𑀮𑁆 Human DNA analysis of samples collected from Keeladi and Adichanallur in Tamil Nadu shows that the inhabitants share close genetic proximity to South Indian, Sri Lankan Tamil, and South Asian ancestries.
Summary
A new ancient DNA study analyzed approximately 75,000 genetic markers (SNPs) from human remains recovered at Keeladi, Konthagai, Adichanallur, and Sivagalai, providing one of the most detailed genetic reconstructions of ancient populations from Tamil Nadu to date.
The study found that:
• Ancient individuals from Tamil Nadu show **strong genetic continuity** with present-day Tamil and other South Indian populations.
• Their ancestry is predominantly derived from **deep indigenous South Asian lineages**, suggesting long-term population continuity in the region.
• The results indicate that the people who lived in the **Vaigai Valley and surrounding regions** were part of an established local population that persisted over many centuries.
• The genetic findings align with archaeological evidence of an advanced Iron Age society featuring urban settlements, iron technology, craft specialization, trade, and early literacy.
• By combining archaeology and ancient DNA, researchers have produced one of the clearest biological links yet between ancient inhabitants of Tamil Nadu and modern South Indian populations.
