Description
MDLP K12d is an ancient-era admixture calculator that decomposes a DNA sample into 12 deep-time ancestral components derived from widely distributed reference groups. It estimates proportions of Arctic, African, Western Hunter-Gatherer (WHG), Siberian, Eastern Hunter-Gatherer (EHG), Southeast Asian (SEA), Caucasus Hunter-Gatherer (CHG), Southern Hunter-Gatherer (SHG), Papuan, Natufian, Neolithic, and Ancestral South Indian (ASI) ancestry. The model is designed for world-wide samples and is useful to anyone interested in understanding the deep, prehistoric layers of genetic heritage: hobbyist genealogists, population geneticists, students, and anyone curious how ancient migrations contributed to today’s genomes.
What this calculator analyzes: MDLP K12d compares an individual’s genetic markers to reference clusters that approximate ancient populations and returns a proportional breakdown. These components act as lenses on major prehistoric events — for example, the spread of Neolithic farming, movements of Eurasian hunter-gatherers, Steppe-related influences captured by EHG/CHG contrasts, and deep southern and Papuan/Southeast Asian signals in Asia and Oceania.
Insights users can gain: quantitative estimates of ancestral contributions linked to archaeological and population histories; patterns that suggest regional affinities, ancient admixture events, or continuity with specific prehistoric groups; and a framework to compare samples across regions or time. The calculator contextualizes results with a genetic narrative: Out-of-Africa dispersals, hunter-gatherer structure across Europe and Siberia, Neolithic farmer expansions, south and southeast Asian deep ancestry (ASI/SEA/Papuan), and Levantine/Natufian influences.
Why it’s valuable: MDLP K12d condenses complex population history into an accessible set of components that are informative for hypothesis generation, teaching, and comparative analyses. Caveats: component labels are simplified shorthand, estimates are
Reference Populations
Arctic
- Indigenous peoples inhabiting the Arctic regions of the world, adapted to the cold climate and traditionally rely on hunting, fishing, and reindeer herding.
African
- Diverse group of populations native to the African continent, with a wide range of ethnic groups, languages, and cultures.
Western Hunter-Gatherer (WHG)
- Hunter-gatherer populations that inhabited Western Europe before the arrival of farmers from the Near East.
Siberian
- Indigenous peoples inhabiting Siberia, a vast region in northern Asia, with diverse ethnic groups traditionally practicing nomadic pastoralism and reindeer herding.
Eastern Hunter-Gatherer (EHG)
- Hunter-gatherer populations that inhabited Eastern Europe before the arrival of farmers from the Near East.
Southeast Asian (SEA)
- Diverse group of populations inhabiting Southeast Asia, a region of great cultural and linguistic diversity.
Caucasus Hunter-Gatherer (CHG)
- Hunter-gatherer populations that inhabited the Caucasus region before the arrival of farmers from the Near East.
Southern Hunter-Gatherer (SHG)
- Hunter-gatherer populations that inhabited Southern Europe before the arrival of farmers from the Near East.
Papuan
- Indigenous peoples inhabiting the island of New Guinea and surrounding islands, genetically distinct from other populations in Southeast Asia and Oceania.
Natufian
- Late Epipaleolithic culture in the Levant region of the Near East, semi-sedentary hunter-gatherers who lived in villages and practiced early forms of agriculture.
Neolithic
- Period of human history characterized by the transition from a hunter-gatherer lifestyle to a settled agricultural lifestyle.
Ancestral South Indian (ASI)
- Ancient population that contributed to the ancestry of modern South Asians, genetically distinct from the Ancient North Indians (ANI).
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 12 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
Key Points
- Your DNA is compared to 12 reference populations
- Modern populations are used as references
- Results show your genetic similarity to these populations
Understanding Your Results
Your results will show percentages of genetic similarity to these reference populations. Remember:
- Results reflect genetic similarity, not direct ancestry
- Ancient populations are used as references
- Percentages indicate relative genetic contribution from each population
- Results are estimates based on available reference data
