Tolan K20 BronzeAge

Tolan K20 BronzeAge is an ancient-era genetic admixture calculator designed to decompose a tested genome against 20 well-chosen reference populations spanning global modern and ancient diversity. Focused on the Bronze Age context, the calculator models how components associated with Anatolian, Caucasus/Iranian, Levantine, Steppe, European, African, East and South Asian, Siberian, Oceanian and Indigenous American ancestries combine in a given sample. Reference groups include ancient Chalcolithic and Bronze Age proxies (Anatolian_CHL, Armenia_CHL, Iran_CHL, Jordan_BA), Steppe-related sources (West-Steppe, East-Steppe, Steppe_to_SCAsian), regional European clusters, multiple African anchors (Mota, West-Africa, North-Africa, East-African), and broad East and Southeast Asian, Siberian, Oceanian, and Amerindian components. Who it's for: researchers, archaeologists, genetic genealogists, educators and curious users worldwide who want an interpretable Bronze Age–centered perspective on ancestry. The calculator is especially valuable for users investigating the spread of farming, Steppe expansions, Bronze Age population turnover, long-distance gene flow into South and Central Asia, and the contributions of ancient Near Eastern and African lineages to later populations. Insights you can gain: proportional ancestry breakdowns that highlight likely contributions from Chalcolithic farmers, Steppe pastoralists, local hunter-gatherer or forager groups, and distal contacts (e.g., Siberian or Oceanian inputs); a framework for comparing modern samples to ancient population baselines; and hypotheses about migration and admixture events that shaped regional gene pools. Results are presented as model proportions that aid interpretation rather than definitive statements about individual histories. Why it’s valuable: by anchoring analyses to Bronze Age and Chalcolithic reference points, Tolan K20 BronzeAge translates complex genetic variation into historically meaningful components. It
