A global Neolithic calculator (by Jonny Cigan) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). A Global Neolithic Calculator is a free Global25 (G25) ancestry calculator by Jonny Cigan that models any profile in the world with the great hunter-gatherer and farmer populations of the Stone Age: Anatolian Neolithic farmers, Western, Eastern and Caucasus hunter-gatherers, Zagros farmers of Iran, Natufians of the Levant, East Siberian and Baikal hunter-gatherers, Yellow River millet farmers of China, the Jomon of Japan, Southeast Asian farmers from Taiwan to Vietnam and Indonesia, Ancient Ancestral South Indians (AASI), early Native Americans, Iberomaurusians of North Africa, East African pastoralists and Sub-Saharan Africans. It is made for everyone, from Europe and Asia to Africa and the Americas, who wants to see their deep ancestry in a single worldwide model. Paste your scaled G25 coordinates to get your best-fit mix, computed directly in your browser. Its reference panel holds about 117 reference populations, grouped mainly as SouthEast Asian Farmers, Sub Saharan Africans, Anatolian Neolithic Farmers, Jomon Hunter Gatherers, Amerindians, Eastern Hunter Gatherers, Western Hunter Gatherers, Baikal Hunter Gatherers.The panel was built or amended by Jonny Cigan.Last updated: November 2026.
People who already have their Global25 (G25) coordinates, for example from a raw DNA file converted with our G25 coordinates service, and want to see how a specific reference panel reads them. Different calculators use different panels, so the same person can get different percentages, and comparing several is more informative than trusting one.
Paste your coordinates, choose a run mode and start the calculation. Each result line is a reference population followed by the share of your ancestry it explains, the shares add up to 100%. Very small shares (below roughly 1 to 2%) are usually noise rather than real ancestry. The distance value tells you how well the mixture reproduces your coordinates: the lower, the better, and a high distance means this panel does not describe you well. For example, a result of "Polish 60 / Ukrainian 25 / Lithuanian 15" means your coordinates are best rebuilt from those three populations in those proportions, not that you descend from three separate groups.
Everything runs in your browser and nothing you paste is uploaded. Browse all Global25 calculators, or let the free Report Finder tell you which regional report fits your ancestry.
