Harappaworld

Harappaworld is a modern-era genetic admixture calculator that estimates the proportional ancestry of an individual using a 16-population reference panel designed to capture major global lineages. By comparing autosomal genotype data to reference clusters — including S-Indian, Baloch, SE-Asian, Siberian, NE-Asian, Caucasian, NE-Euro, Eastern_Euro, Mediterranean, Papuan, American, Beringian, San, E-African, Pygmy, and W-African — the tool reconstructs the mosaic of ancestry components that together reflect deep and recent population history. Designed for a worldwide audience, Harappaworld is appropriate for genealogy enthusiasts, adoptees, community historians, educators, and researchers who want a broad, interpretable view of genetic ancestry. Users receive proportional breakdowns, visual bar plots and maps, and contextual notes that explain how each component ties to known prehistoric and historic movements: Out-of-Africa dispersals (San, Pygmy, W-African, E-African), Eurasian diversification (Caucasian, Mediterranean, NE-Euro, Eastern_Euro), South Asian complexity (S-Indian, Baloch), East and Northeast Asian spread (SE-Asian, NE-Asian, Siberian), and the settlement of Oceania and the Americas (Papuan, Beringian, American). Harappaworld emphasizes interpretation: components indicate shared genetic drift with reference populations rather than fixed ethnic labels, providing insight into relative affinities, likely admixture events, and regional ancestries. The calculator is valuable because it integrates diverse global references into a single framework, helping users contextualize personal and population-level histories, generate hypotheses about migration and contact, and compare results across samples or time-slices. Limitations and best practices are clearly stated: results are model-based estimates dependent on the chosen reference panel, marker density, and modern population structure. Harappaworld is not a definitive statement of cultural or social identity
