Largely local and long-lived. Southern Caucasus peoples, Georgians among them, are the closest living match to the Caucasus hunter-gatherer lineage documented in Georgia itself 13,000 to 10,000 years ago, blended with Anatolian farmer-related and other Near Eastern ancestry, and the south largely kept its Bronze Age profile after that. Ancestrify models each era from your raw DNA. Two caves in western Georgia — Satsurblia and Kotias Klde — produced genomes that changed how all of West Eurasian ancestry is modelled. For most nations, ancient DNA tells a story of arrivals; for Georgians, it mostly tells a story of *staying*. That makes Georgian ancestry one of the cleanest continuity cases in the entire literature, and worth telling carefully. > **The short answer:** southern Caucasus peoples, Georgians among them, are the closest living > match to the Caucasus hunter-gatherer (CHG) lineage documented in Georgia itself 13,000 to > 10,000 years ago. Their ancestry blends it with Anatolian farmer-related and other Near Eastern > ancestry, and the south largely kept its Bronze Age profile after that. ## The genomes that named a lineage Jones et al. 2015 sequenced a Late Upper Palaeolithic man from Satsurblia cave (~13,300 years old) and a Mesolithic man from Kotias Klde (~9,700 years old). They formed their own deep branch of West Eurasian ancestry — split from western European hunter-gatherers tens of millennia earlier — and the paper named it: **Caucasus hunter-gatherers, CHG**. The label you now see in every [admixture calculator](/lab/admixture) and half the qpAdm source lists in the literature is, concretely, these Georgian individuals and their relatives. CHG turned out to be load-bearing far beyond the Caucasus: in the 2015 estimate, roughly half the ancestry of the [Yamnaya steppe pastoralists](/blog/yamnaya-dna-steppe-origins), and through them [most modern European populations](/blog/how-to-measure-steppe-ancestry-percentage), plus a major contribution to the West Eurasian-related ancestry of South Asia. Genetically, the Caucasus was not a periphery; it was a wellspring. ## Farmers arrive, the blend sets Through the Neolithic and Chalcolithic, Anatolian farmer-related ancestry spread into the South Caucasus and mixed with the local CHG base. By the Early Bronze Age, **Kura-Araxes** genomes (~3500 to 2500 BCE; Wang et al. 2019 sampled them in Dagestan and Armenia) continue that local profile: a cline between CHG and Anatolian Chalcolithic-related ancestry, with Kura-Araxes individuals also carrying about a quarter Iran Chalcolithic-related ancestry in one model. Wang et al. find that southern Caucasians largely retained this Bronze Age ancestry profile through the centuries of Colchis and Iberia, the Roman and Persian spheres and the medieval kingdoms, though ancient DNA from those periods is still needed to test it directly. Wang et al. 2019's wider finding is the opposite of a wall: in prehistory "the Caucasus was no barrier to human movement". The genetic divide between north and south formed only after the Bronze Age, when the north received additional steppe ancestry and the south did not. ## What modern Georgian genomes show Modern samples — Georgians in worldwide reference panels, regional studies of the Caucasus — repeat three findings. **High continuity:** Georgians consistently model with among the highest CHG-related shares of any modern population, highest in highland groups (Svans, mountain easterners), grading gently toward more Anatolian-related weight in the west. **Tight regional clustering:** Georgians sit with Abkhazians, Circassians and other South Caucasus neighbours, nearer [Armenians](/blog/armenian-dna-ancient-origins) than to either the steppe or Iran — geography over politics, as usual. **Old uniparentals:** Y-DNA is dominated by G2a (a lineage tied to the Neolithic and Caucasus since antiquity) and J2, with the highland valleys carrying founder-effect spikes — one valley, one dominant surname-lineage — that make [haplogroup readings](/blog/how-to-find-y-dna-haplogroup) especially local here. The gaps worth naming: sampled ancient genomes from Georgia cluster in the west and the prehistoric periods; the classical-to-medieval transect (Colchian, Iberian, Bagratid-era genomes) is thin, so continuity through *those* centuries is inferred from the endpoints rather than watched happen — the same honest caveat every [continuity story](/blog/albanian-dna-ancient-origins) owes its readers. ## Reading your own results - **[G25 distances](/lab/g25-distance):** modern era led by Georgian and neighbouring Caucasus averages; ancient eras led by Kura-Araxes-related and CHG-related samples — one of the few ancestries where the *deepest* era's leaders are from your own territory. - **[Admixture fits](/lab/admixture):** expect CHG-related plus Anatolian-related to carry the model. CHG-vs-Iranian-Neolithic is the classic [collinear pair](/blog/g25-source-selection-overfitting) here — the two are close relatives, and panels that offer both will split them unstably. - **[qpAdm](/qpadm):** Georgian genomes are rewarding formal targets precisely because the deep sources are locally anchored — and the [right set has to work hard](/blog/how-to-choose-qpadm-sources-and-outgroups#the-standard-right-sets) to separate CHG from its Iranian-related sister stream. A model record that says the data cannot fully distinguish them is [reporting honestly](/blog/qpadm-model-record-explained). ## Frequently asked questions ### Are Georgians "descended from the Caucasus hunter-gatherers"? In substantial part, yes — that is the rare case where the slogan matches the models. With the standard caveat: blended with Anatolian farmer-related ancestry since the Neolithic, so no living person is *a* CHG. ### How much steppe ancestry do Georgians have? Little. Wang et al. found that the north received additional steppe ancestry after the Bronze Age, while southern Caucasians largely kept their Bronze Age profile. Small steppe-related percentages in hobby calculators are usually [reference-panel artefacts](/blog/why-admixture-calculators-disagree) or the CHG kinship showing through, since steppe ancestry is itself half CHG-related. ### Is Georgian ancestry the same as Armenian? Close neighbours built from the same deep streams in different ratios — Armenians carry more Anatolian-related weight and [a documented Bronze Age steppe pulse](/blog/armenian-dna-ancient-origins) that Georgians largely lack. Distinguishable, and mutually each other's nearest comparisons. Terms used here are defined in the [glossary](/glossary). ## Sources and further reading 1. Jones, E. R. et al. (2015).
