A groundbreaking genomic study published in Genomics of the Silk Road has analyzed the ancient DNA of 45 individuals from the Sirkap excavations in Taxila. The results provide a detailed look at the demographic shifts that occurred in North-Western India during the 1st and 2nd centuries CE, corresponding to the arrival of the Shaka (Scythian) and Kushan tribes.
The data reveals a complex 'melting pot' of genetic lineages, where Central Asian steppe ancestry fused with local Indo-Aryan populations. This genetic blending mirrors the syncretic art and culture of the Gandhara region, where Greek, Buddhist, and Vedic influences converged. The study also identified specific alleles associated with immunity to diseases likely brought by increased trans-continental trade.
- Maternal Lineages: The study found that local maternal lineages remained dominant, suggesting that the incoming groups were primarily male-dominated military and merchant classes.
- Dietary Insights: Isotopic analysis of teeth indicates a shift from millet-based diets to more wheat and meat consumption following the Kushan expansion.
- Social Mobility: High-status burials showed a wider variety of genetic backgrounds, indicating a meritocratic or multi-ethnic ruling elite.
