Global Ancestry K23 2013

Highly diverse populations representing many of the largest ethnic groups in West Africa, with major linguistic families including Niger-Congo and Afroasiatic members. Nigeria’s population reflects long histories of migration, state formation and trade, producing significant genetic, cultural and linguistic structure across the country. The region is a major contributor to West African ancestry profiles globally.

Populations of the Senegambia region with deep historical roots in West Africa and strong cultural traditions such as trade, Islamization and state systems. Genetic patterns show mixtures typical of Atlantic West Africa, with some Saharan and Sahelian influences due to long-distance connections. Languages and ethnic identities in the region are diverse and historically interconnected.

Populations of the Eurasian steppe and highland zones with complex histories of pastoralism, empire-building and migration connecting East and West Asia. Genetic and cultural signatures reflect admixture among Indo-Iranian, Turkic and Siberian lineages shaped by successive waves of mobility along the Silk Road. Modern Central Asian groups are highly heterogeneous across geography and language.

Populations from East Asia encompassing major cultural centers such as China, Korea and Japan, with long-standing agricultural and urban traditions. Genetic profiles often show shared Northeast Asian ancestry components alongside regional differentiation driven by language families like Sino-Tibetan, Japonic and Koreanic. The region has been central to demographic expansions, technological diffusion and state formation in Eurasia.

Peoples of the Indian subcontinent exhibiting high genetic, linguistic and cultural diversity shaped by ancient settlement, migrations and long-term regional structure. Major contributions come from Indo-Aryan and Dravidian language families alongside numerous tribal and isolated groups, producing complex admixture patterns. South Asia has been a major crossroads for gene flow between West, Central and Southeast Asia.

Populations of Eastern Europe often associated with Slavic language families and shaped by migration waves, imperial borders and steppe interactions. Genetic patterns show a mix of local European hunter–farmer and steppe-derived ancestries, with regional variation across the Balkans, Carpathians and plains. Historical processes such as medieval migrations and population turnovers contributed to modern structure.

Western European populations shaped by Neolithic farming expansions, later Bronze Age and historic migrations, and long-term regional cultural exchange. Genetic composition typically includes European hunter–gatherer, early farmer and steppe-derived components, with local differentiation across France, Benelux and adjacent areas. Cultural legacies include Romance, Germanic and Celtic influences.

Groups in northern Europe with Finno-Ugric (Uralic) linguistic roots and significant historical contact with Slavic populations of northwest Russia. These populations show genetic features reflecting northern hunter–gatherer ancestry, Uralic-related influxes, and regional adaptations to boreal environments. Cultural identities include Saami and Finnish-speaking communities with distinct traditions.

Populations from the British Isles with complex ancestry formed by Celtic, Roman, Anglo-Saxon, Viking and Norman layers over millennia. Genetic structure in Great Britain varies regionally, reflecting both ancient continuity and later migrations that shaped language and identity. Southern England in particular has a distinct profile influenced by successive continental contacts.

Populations of Spain and Portugal with deep Mediterranean and Atlantic connections, reflecting pre-Roman, Roman, Visigothic and Islamic periods. Genetic signals include Paleolithic/Mesolithic continuity, Neolithic farmer influxes and later North African and steppe contributions, producing marked regional variation including unique Basque ancestry in parts of northern Spain. Languages and cultural identities are diverse across the peninsula.

Native Irish populations with a strong Gaelic cultural heritage, shaped by ancient Atlantic and continental European interactions. Genetic profiles show influences from Mesolithic hunter–gatherers, Neolithic farmers and later Bronze Age movements, with regional continuity and some Viking and Norman signals in coastal areas. Ireland’s island history has produced distinct genetic and cultural patterns within the British Isles.

Populations of southern Europe centered on the Italian peninsula and Greece, home to ancient Mediterranean civilizations with long histories of maritime trade and migration. Genetic diversity includes Neolithic farmer, indigenous hunter–gatherer and steppe-derived ancestries, with strong regional differentiation linked to historical colonization and trade networks. Cultural legacies from classical antiquity remain influential across language, art and archaeology.

Northern European populations associated with Norse and Germanic linguistic traditions and a shared Viking Age heritage that influenced large parts of Europe. Genetic composition combines northern hunter–gatherer, Neolithic farmer and steppe-related ancestries, with local continuity and adaptation to high-latitude environments. Modern Scandinavian societies reflect both ancient lineages and historical mobility across the North Sea and Baltic.

Populations of the Caucasus region characterized by exceptional linguistic, cultural and genetic diversity across mountainous terrain between the Black and Caspian Seas. The area is home to multiple language families (Kartvelian, Northwest and Northeast Caucasian) and has served as a refuge and crossroads for gene flow between Europe and Asia. Local groups often preserve distinct genetic lineages and ancient cultural practices.
