Orbis Terrarum Ancestralis K54
Orbis Terrarum Ancestralis K54 is a curated K=54 admixture calculator that estimates global ancestry proportions using 54 carefully chosen reference populations. Built for researchers, genealogists, and enthusiasts, it reveals fine-grained regional signals—from African hunter‑gatherers and Eurasian clusters to Austronesian, Indigenous American, and Jewish diaspora components—illuminating deep and recent migration histories with transparent, interpretable results.

Über diesen Rechner
Orbis Terrarum Ancestralis K54 is a curated K=54 genetic admixture calculator that decomposes a person’s genome into contributions from 54 globally distributed reference populations. Designed for researchers, genealogists, ancestry enthusiasts, and historians, it blends modern and ancient-informed reference clusters—spanning African hunter‑gatherers, multiple African and Eurasian regional groups, South and Southeast Asian clusters, Oceanian and Pacific lineages, Indigenous American and Arctic groups, and numerous European, Middle Eastern, and Jewish diaspora components. The result is a fine-grained portrait of continental and subcontinental ancestry signatures.
This calculator analyzes genome‑wide allele frequencies against carefully selected reference panels to estimate proportional ancestry, exposing both deep historical signals (for example, Out of Africa, Neolithic and Bronze Age movements, Bantu expansions, Austronesian dispersals, and Indigenous American settlement) and more recent regional admixture. Users gain quantitative proportions, comparative context, and interpretive guidance that highlight likely source regions and plausible migration narratives while noting uncertainty and limits of resolution.
Orbis Terrarum Ancestralis K54 is valuable because it balances breadth and specificity: 54 curated clusters provide greater regional discrimination than broad continental models, without overfitting to noise. It supports cross‑population comparisons, hypothesis testing, and educational exploration of human population history. The calculator emphasizes transparency about reference choices and limitations—ancestry estimates are probabilistic, influenced by reference sampling and historical complexity. Whether you are tracing family history, investigating population structure, or adding context to archaeological and historical research, this tool offers a clear, professional, and accessible pathway to understanding how global ancestry components combine to form

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 54 sorgfältig ausgewählte moderne und antike Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
