Eurasia K20

Eurasia K20 is a 20‑component admixture calculator designed to dissect global ancestry using a balanced set of modern and ancient proxy populations. It quantifies the proportional contributions from diverse reference groups — from NE_ASIAN, E_ASIAN and E_SIBERIAN components in Northeast Asia to YAMNAYA, EUROPEAN, EEF and CAUCASUS_GEDROSIA representing major West Eurasian and steppe-related ancestries. It also models South and Southeast Asian signals (S_INDIAN, KALASH, SE_ASIAN1/2), hunter‑gatherer ancestries (SHG_WHG), as well as non‑Eurasian components such as N_AMERINIDIAN, S_AMERINDIAN, PAPUAN, PYGMY, KHOISAN and SSA (sub‑Saharan African). SW_ASIAN and W_SIBERIAN complete the panel to capture intermediate and northern Eurasian diversity. Who it’s for: Eurasia K20 is aimed at researchers, students, genetic genealogy enthusiasts and anyone curious about deep and recent ancestry across the world. Because the reference panel mixes modern and ancient proxies, it is well suited to explore long‑range migration signals (for example Neolithic farmer expansion, steppe migrations and East Asian/Siberian movements) alongside recent admixture patterns in individuals and populations. What you learn: The calculator provides a concise breakdown of ancestry proportions, highlighting major ancestral sources and gradients. Users can detect whether a profile reflects stronger farmer, hunter‑gatherer, steppe, South Asian, East Asian, Siberian, Oceanian, American or African influence. Results help place personal or population histories in broader prehistoric and historic contexts. Why it’s valuable: By using 20 thoughtfully chosen reference groups, Eurasia K20 offers granular resolution across Eurasia and beyond while remaining interpretable. It bridges ancient and modern signals to reveal both deep population structure and recent gene flow. Note: as with all admixture models, results are approximations based on proxy populations and should be interpreted alongside archaeological,
