West Eurasian Bronze Age-Neolithic Calculator (by Jonny Cigan) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). West Eurasian Bronze Age-Neolithic Calculator is a free Global25 (G25) ancestry calculator by Jonny Cigan, an updated version of his earlier calculator. It models your DNA with the populations that built West Eurasia between the Neolithic and the Bronze Age: Early European Farmers (Globular Amphora, megalithic and Late Neolithic farmers from Britain, Ireland, France, Iberia, Switzerland and Sweden), Yamnaya and Catacomb steppe herders from Ukraine to Kazakhstan, Western, Baltic and Scandinavian hunter-gatherers, Bronze Age Caucasians (Maykop, Kura-Araxes), Anatolians, Canaanites and Mesopotamians, the Bronze Age of Central and South Asia (BMAC, Shahr-i-Sokhta, Indus Valley profile, AASI), eastern steppe nomads, and North and Sub-Saharan Africans. It is made for West Eurasian profiles that want a detailed Neolithic and Bronze Age breakdown. Paste your scaled G25 coordinates to get your best-fit mix, computed directly in your browser. Its reference panel holds about 133 reference populations, grouped mainly as Early European Farmers, Western Steppe Herders, Sub Saharan Africans, Baltic Hunter Gatherers, Bronze Age Caucasians, Canaanites, Western Hunter Gatherers, Eastern Steppe Nomads.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.
