Who were the Baltic (BC 200 – 600 AD)?

Baltic is one of the 27 curated source populations in the Classical Antiquity era of the Ancestrify qpAdm analysis: a group of published ancient genomes from one archaeological context, pooled as a single reference the model can test your genome against.

Does Baltic in my result mean they were my ancestors?

No. A source population is a reference the model tests against, never a statement about who your ancestors were. A coefficient on this source means the ancestry those burials represent helps explain your genome to within statistical noise — similar ancestry composition, not descent from those individuals. Ancestrify never claims a population is your ancestor.

What does a Baltic percentage in a qpAdm model mean?

qpAdm estimates the mixture proportions that best explain your genome as a combination of the chosen sources, given a fixed set of outgroup (right) populations, and reports a p-value for whether the model is statistically acceptable together with a standard error for every proportion. The percentage is that estimated share, with its uncertainty published beside it.

How do I get a qpAdm model that uses Baltic?

Order the Ancestrify qpAdm analysis (€29.99, one-time) and upload the raw file you already have from a consumer test. Your genome is merged into the AADR reference panel and modelled across both eras; each era's model is built from that era's source populations, so a model for the Classical Antiquity era draws on Baltic where it improves the fit.

Can I model Baltic ancestry for free first?

Yes. The Ancestrify Lab runs Global25 admixture calculators, a nearest-populations distance tool and an AdmixTools 2 workbench in your browser with no account, and several calculators cover the Classical Antiquity era. Those are G25 fits, not formal qpAdm models — the paid analysis is the one with a p-value.

Who they were

Artistic interpretation of the Baltic (AI-generated artwork, not documentary evidence)

Period: BC 200 – 600 AD
Era in the analysis: Classical Antiquity
Region: Eastern Baltic
Role in the model: Source (left) population — a reference qpAdm tests against

The Iron Age population of the eastern Baltic — present-day Lithuania, Latvia and Estonia — descended from the Corded Ware herders who had arrived on the coast around 2800 BC, mixed over the following millennia with the region's dense Mesolithic hunter-gatherer population. Ancient genomes show this group carrying the highest proportion of hunter-gatherer ancestry anywhere in Europe and, from the Bronze Age onwards, a small but distinctive Siberian-related component that arrived from the east alongside Y haplogroup N (Mittnik et al. 2018; Saag et al. 2019).

This ancestry is the foundation of present-day Lithuanians, Latvians and Estonians and is closely related to the populations of Belarus, north-western Russia and Finland. In the model it is the north-easterly pole of European variation, distinct from the Germanic source in its higher hunter-gatherer share and from the Finno-Ugric Volga source in its lower Siberian-related share.

In Ancestrify's qpAdm service, Baltic is a source in the "Classical Antiquity" era. The report shows its weight with a standard error and a Z-score, so you can see not only how much of the model it carries but how confidently that share is separated from zero, and a model that cannot support it is rejected rather than published. For genomes from the Baltic states, Belarus and north-western Russia it usually carries the largest weight; read it together with the Early Slavic and Finno-Ugric Volga sources, which the model may find hard to separate.

Y haplogroups R1a-Z280 and N-L1025, and mtDNA H, U5 and U4, are typical of these samples. A haplogroup alone is never evidence of a share.

In your report
Represents the Iron Age populations of the eastern Baltic region, positioned at the genetic boundary between Western Hunter-Gatherers (WHG) and Eastern Hunter-Gatherers (EHG) and reshaped during the 1st millennium BCE by the arrival of Siberian-related ancestry linked to Uralic-speaking populations from the east. Earlier Mesolithic and Neolithic Baltic foragers carried mixed WHG and EHG ancestry with additional Ancient North Eurasian (ANE) admixture, and the eastern Baltic was one of the last regions in Europe to adopt farming. Iron Age individuals from Lithuania, Latvia, and Estonia retain this deep forager-descended substrate together with Corded Ware-derived steppe ancestry. The proto-Baltic tribes ancestral to later Balts, Prussians, and Curonians occupied this territory alongside Finnic speakers during Classical Antiquity, with the region serving as a genetic contact zone between Germanic, Slavic, and Finno-Ugric populations. Baltic ancestry remains an important reference component in admixture models of Northern and Eastern Europe.

Where this population sits in the model

The Ancestrify qpAdm analysis models your genome once per era. The Classical Antiquity era has 27 curated source populations, and Baltic is one of them: every candidate model for that era is a combination of these sources, tested against a fixed set of outgroup populations, and only a model that passes the statistical fit check is published — with a p-value, and a standard error on every proportion.

A reference, not a verdict: every population on this page is a source the model tests your genome against — a well-sampled point in ancient genetic space that a mixture of ancestries can be expressed in terms of. A weight on it means your genome is well described as partly resembling those people; it is never a statement that they, specifically, were your ancestors, and a population that fits well is not the only one that could.

Model it yourself for free

The Ancestrify Lab runs in your browser, with no account. Paste a Global25 row into an admixture calculator that covers the Classical Antiquity era, rank the closest ancient populations in the distance tool, or run f4, qpWave and qpAdm on the public panel in the AdmixTools 2 workbench. These are Global25 fits and exploratory statistics, not the formal qpAdm model of the paid analysis.
