Anatolian Iron Age: Turkey_IA

The Turkey_IA assemblage (1000–100 BCE) is a mosaic of communities occupying strategic valleys and plains across Anatolia. Excavated skeletal remains come from Kuriki Höyük in Batman province (southeast), the fortified site of Çavuştepe in Van province (east), and Gordion near modern Ankara (central Anatolia). Archaeological contexts point to villages, fortified citadels and elite burials that reflect Iron Age political landscapes — from local chiefdoms to the territorial states that emerged after the Late Bronze Age collapse.

Archaeological evidence indicates continuity with earlier Bronze Age settlement patterns while also showing new material languages: ironworking, expanded trade networks, and changing burial rites. Genetically, the maternal profile (mtDNA) of the 15 individuals is dominated by haplogroups U, J and H. Haplogroup U often persists through deep Anatolian prehistory and may reflect local continuity, while J and H are widespread in the Near East and Mediterranean and suggest persistent regional connections. The dataset's moderate size and uneven geographic spread mean these patterns are best read as regional tendencies rather than exhaustive population histories. Limited or uneven recovery of Y-chromosome markers prevents definitive statements about paternal ancestry or male-mediated migration at this time.

The genetic portrait of Turkey_IA is anchored by mitochondrial DNA from 15 individuals: U (4), J (3), H (2), N (1), and an H+ designation for one individual. Haplogroup U has deep roots in Anatolia and Europe and is often interpreted as signaling long-term regional continuity; its presence across sites suggests maternal line persistence from earlier Bronze Age and Neolithic populations. Haplogroups J and H are common across the Near East and Mediterranean and likely reflect continued connections — through trade, marriage networks, and regional mobility — linking central and eastern Anatolia to broader cultural spheres.

Crucially, Y-chromosome data are not consistently represented for these samples, limiting confident statements about paternal lineages and patterns of male-mediated migration. Without robust Y-DNA or genome-wide autosomal data for all individuals, assertions about large-scale population replacement or major influxes remain speculative. That said, the mtDNA profile is compatible with a model in which local maternal ancestry persists while male-linked ancestry and autosomal admixture may have been more variable through time, reflecting social practices, elite mobility and regional alliances. Future genome-wide analyses and larger sample sizes will be needed to resolve admixture proportions and to test models of continuity versus incoming gene flow.
