Basal Eastern Asia Ancestral

Basal Eastern Asia Ancestral estimates deep prehistoric ancestry using eight ancient reference genomes. It decomposes genomes into components tied to Tianyuan, Jomon, Xingyi, Hoabinhian, ANS_ANE, WHG_UP, Mbuti and WestAfrican lineages, offering global users—researchers and enthusiasts alike—insight into ancient East Asian diversification, prehistoric migrations, and hidden ancestral signals.

About This Calculator

The Basal Eastern Asia Ancestral calculator quantifies deep, ancient ancestry components using a panel of carefully chosen Upper Paleolithic and early Holocene reference genomes. It models contributions from eight reference populations—Xingyi_EN, Jomon, Tianyuan_UP, Hoabinhian, ANS_ANE, WHG_UP, Mbuti, and WestAfrica—to estimate how much of an individual’s or population’s genome traces to major prehistoric lineages. Designed for researchers, genetic genealogy enthusiasts, students of human prehistory, and anyone curious about ancient population structure, this tool focuses on the Ancient era and is applicable to global samples. What it analyzes: Using allele-sharing patterns and comparative modelling against ancient reference genomes, the calculator deconvolves genomes into component ancestries that reflect major demographic episodes in Eurasia and beyond. It highlights deeply divergent East Asian lineages (e.g., Tianyuan_UP, Xingyi_EN), island hunter-gatherer heritage (Jomon), Southeast Asian hunter-gatherer roots (Hoabinhian), Ancient North Eurasian signals (ANS_ANE), Western European hunter-gatherer input (WHG_UP), and baseline sub-Saharan African variation (Mbuti, WestAfrica). Insights you can gain: Users learn proportional ancestry estimates tied to prehistoric migrations, admixture events, and persistence of archaic lineages. The calculator clarifies whether apparent East Asian ancestry reflects recent admixture or derives from basal, deeply diverged Eastern lineages; it can reveal hidden Ancient North Eurasian or WHG contributions and contextualize African ancestry relative to ancient sub-Saharan variation. Historical/genetic context: The selected references span key geographic and temporal anchors across Eurasia and Africa, enabling interpretation of how Ice Age expansions, coastal migrations, and local hunter-gatherer persistence shaped modern genomes. Why it’s valuable: By framing modern DNA against ancient genomes, this calculator offers a robust, intu

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 8 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 8 reference populations
Ancient populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
