摘要: Summary Across Europe, the genetics of Chalcolithic/Bronze Age transition is increasingly characterized in terms an influx Steppe-related ancestry. The effect this major shift on genetic structure populations Italian Peninsula remains underexplored. Here, genome-wide shotgun data for 22 individuals from commingled cave and single burials Northeastern Central Italy dated between 3200 1500 BCE provide first genomic characterization Bronze (n = 8; 0.001–1.2× coverage) central Peninsula, filling a gap literature 1950 BCE. Our study confirms diversity ancestry components during Chalcolithic arrival as early 1600 BCE, with component increasing through time. We detect close patrilineal kinship burial patterns away (2200–900 BCE) along lowered runs homozygosity, which may reflect larger changes population structure. Finally, we find no evidence that directly led to frequency 115 phenotypes present dataset, rather post-Roman Imperial period had stronger influence, particularly variants associated protection against Hansen’s disease (leprosy). provides closer look at local dynamics demography phenotypic shifts they occurred part broader phenomenon widespread admixture transition.
