The rich cultural and genetic diversity of South Asia is the result of multiple migrations and cultural assimilations. The Parsi community of North-western India, who migrated from West Eurasia in the 7th century CE, has both Middle Eastern and South Asian genetic components. In this study, we analyzed the complete mitogenome of 19 ancient Parsi settlers and found that their maternal ancestry includes both South Asian and Middle Eastern genetic composition.
The rich cultural and genetic diversity of South Asia emerged from multiple migrations and cultural assimilation of multiple waves of migrants. The Parsi community of North-western India were one of those who migrated from West Eurasia in the aftermath of 7th century CE and assimilated into the local cultural framework. Earlier genetic studies further strengthened this notion with the finding that they harbour both Middle Eastern and South Asian genetic components. Although these studies covered both autosomal and uniparental markers, still maternal ancestry was not covered in depth and with good resolution of mitochondrial markers. Hence in our current study, we have first time generated a complete mitogenome of 19 ancient samples of the first Parsi settlers excavated from the archaeological site of Sanjan and performed detailed phylogenetic analysis to infer their maternal genetic affinity. In our analysis, we found that the Parsi mitogenome with mtDNA haplogroup M3a1 + 204 shares clade with both Middle Eastern and South Asian modern individuals in both the Maximum Likelihood tree and Bayesian phylogenetic tree. This haplogroup was also prevalent among the medieval Swat valley population of present-day Northern Pakistan and was also observed in two Roopkund A individuals. In the phylogenetic network this sample share haplotype with both South Asian and Middle Eastern samples. So conclusively, the first Parsi settlers' maternal ancestry encompasses both South Asian and Middle Eastern genetic composition.
