Argaric Bronze of Southeast Iberia

The Argaric phenomenon in southeast Iberia emerges in the early Bronze Age as densely inhabited hilltop towns and fortified settlements. Archaeological data indicates a florescence of metallurgy, craft specialization, and stratified burial practices from sites such as La Almoloya (Pliego), La Bastida (Totana) and Cerro del Morrón (Moratalla). Radiocarbon dates spanning 2192–1000 BCE frame a long arc of social transformation: earlier communal burial traditions give way to intramural tombs and differentiated grave goods that suggest increasing social inequality.

Material culture — fine pottery, bronze tools, and sealed storage — points to intensified control of resources and landscape. El Argar (La Almoloya) in particular yields monumental domestic architectures and elite burials containing rich assemblages. Limited evidence suggests exchange networks with other Iberian groups and Mediterranean contacts, but the scale and directionality of those ties remain debated. The genetic sampling of 82 individuals concentrated in Murcia allows a regionally focused view of population continuity and change, while acknowledging that these sites capture only part of a diverse Iberian mosaic.

Genetic analysis of 82 individuals from multiple Argaric sites in Murcia offers a moderate-sized dataset for examining ancestry, kinship, and sex-biased patterns. Y-chromosome results show a strong predominance of haplogroup R (38 individuals) with a single occurrence of E (1 individual). Mitochondrial diversity is higher: haplogroups K (19), U (15), H (12, including H1 = 8), and T (4) are common. These distributions suggest patrilineal clustering alongside diverse maternal lineages, consistent with household-based social organization and possible male-line continuity in some lineages.

Interpreting these patterns requires caution. Haplogroup R in Europe is often associated with populations carrying Steppe-related ancestry in other contexts, but assigning broad migratory narratives to the Argaric record would be premature without genome-wide ancestry profiles. The mtDNA mix indicates enduring local maternal diversity and potential female mobility between communities. Kinship analyses at cemetery and household scales can reveal family focal points within settlements; preliminary osteogenetic ties at La Almoloya and La Bastida support the presence of related individuals interred in close domestic contexts. While sample size (82) is substantial compared with many ancient collections, geographic concentration in Murcia limits broader Iberian generalizations, and further genome-wide data will refine models of migration and social organization.
