Who lived in Late Precolonial California (1000 to 1450 AD)?

Late Precolonial California is one of the 183 curated source populations in the Bronze Age to Middle Ages era of Ancient Ancestry, Ancestrify's qpAdm analysis: a group of published genomes pooled as a single reference the model can test your genome against. These are ancient individuals from one archaeological context wherever the record holds them, and present-day genomes standing in where it does not, which the description on this page says.

Does Late Precolonial California in my result mean the people there 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 Late Precolonial California 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 Late Precolonial California?

Order Ancient Ancestry, Ancestrify's 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 Bronze Age to Middle Ages era draws on Late Precolonial California where it improves the fit.

Can I model Late Precolonial California 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. Ancient Ancestry, the paid analysis, is the one with a p-value.

Where this population sits in the model

Ancient Ancestry, our qpAdm analysis, models your genome once per era. The Bronze Age to Middle Ages era has 183 curated source populations, and Late Precolonial California 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.

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 Ancient Ancestry.
