Genetic data from the Scotland_MBA dataset (5 individuals) provides tantalizing but preliminary glimpses into Middle Bronze Age ancestry in Scotland. Y-chromosome haplogroups observed include R (2 individuals) and I (1 individual), while mitochondrial lineages are dominated by H (4 individuals) with a single U.
Mitochondrial haplogroup H is widespread across Europe in the Bronze Age and today, and its prevalence here aligns with broader maternal continuity in western Europe. Haplogroup U has deeper Mesolithic roots and appears intermittently in Bronze Age contexts. The presence of R and I Y-lineages reflects a mix of paternal ancestries; R types are common across Bronze Age Britain, often associated in broader studies with steppe-derived expansions, while I lineages can reflect older regional male lineages.
Because the sample size is small (<10), patterns should be treated as provisional: they suggest a community with largely European maternal ancestry and mixed paternal signals, consistent with Bronze Age demographic processes of continuity and mobility. Future, larger datasets will be needed to confirm fine-scale population structure, sex-biased migration, and connections to neighboring regions.
