The genetic dataset includes 60 modern samples collected from Iranian sites (Urmia, Adeh, Gug Tappeh, Shiraz, Bandar Abbas, Babol, Khoramabad) and from migrants sampled in Kuwait and Israel. With this sample size, population-level signals begin to emerge, but interpretation must remain cautious: 60 modern genomes provide insight into recent population structure and admixture, but cannot substitute for time-stamped ancient DNA when inferring deep demographic events.
Preliminary patterns indicate substantial heterogeneity across sampled locales. Coastal and Caspian samples show affinities consistent with long-contact maritime and littoral connections; northwestern samples around Urmia show increased affinity to populations of the southern Caucasus and Anatolia in comparative analyses, consistent with archaeological ties in that region. Inland and mountainous samples (Lorestan) often show signals of relative local continuity and isolation. Because the dataset is modern, recent admixture—over the past centuries—contributes to observed diversity. Precise assignment to Y-DNA or mtDNA haplogroups was not uniform across the dataset; broadly, maternal and paternal lineages are mixed, reflecting Iran’s role as a crossroads.
Further work integrating autosomal analyses, haplogroup calls, and comparisons to ancient genomes from the Iranian plateau and neighboring regions is essential. Where specific site sample counts are low (<10), results should be treated as preliminary and hypothesis-generating rather than definitive.
