IBD кластеризација даје одговоре на нека важна питања о саставу становништва одређених археоложских култура.
Бјелбарци су несумљиво били Скандинавци са минорним удјелом BAL генетике около 7%.When applying our supervised ADMIXTURE121 model at K = 12 to 46 Bronze Age, Iron Age, Roman Period, and early medieval groups from Central and Northern Europe, we find that Wielbark individuals exhibit on average 54% ± 4% NOR (Northern Scandinavian) and 21 ± 3% CNE (Southern Scandinavian or North Sea coast) ancestry, but only neglectable fractions of BAL ancestry (7% ± 2%), which is the most dominant ancestry among genomes from the succeeding Slavic period (63% ± 2%). The same pattern is evident in terms of IBD-sharing, with the Wielbark individuals sharing on average 5.02 ± 0.02 cM IBD segments with present-day Swedish and 4.61 ± 0.03 cM IBD segments with present-day Danish, yet only 3.41 ± 0.11 cM with present-day Poles or 3.17 ± 0.17 with present-day Ukrainians.
Кластер 2.3 (источноевропски BAIA) се дијели на источни и западни. У источни дио спадају узорци из Тшињец и Комаровске културе, а у западну дио Тшињец, Мезечат и култура инкрустиране керамине.
Cluster 2.3 (“EasternEurope BAIA”) contains mostly individuals from Bronze and Iron Age Czech Republic, Hungary, Slovakia, Ukraine and Poland. It can be further split in clusters 2.3.1 (“EasternEurope BAIA West”), which contains most of the genomes from Czech Republic and Hungary, and cluster 2.3.2 (“Eastern Europe BAIA East”), which contains most of the samples from Poland, Ukraine and Slovakia.
Комаровци, Стрижовци, Литавци, Римљани са западнога Балкана везује један дријевни суперкластер, али само Литавци BA је предачки Словенима, а остали нису.
When directly comparing the IBD-sharing patterns (> 1 cM) between the SP population of Gródek (used here as proxy for the original SP gene), and other Bronze Age, Iron Age and Roman Period groups in Europe, we find the highest IBD sharing with Iron Age (Barrow Culture) and Roman Period individuals from Lithuania, followed by Roman Period individuals from Croatia and Serbia, as well as as Bronze Age individuals from Ukraine (Komarów Culture) and eastern Poland (Strzyżów Culture). Thus, highest genetic relatedness is established with these individuals and groups, although they form their own respective IBD clusters, suggesting an ancestral connection that predates more recent connections to East-Central Europe and the Balkans.
Осим тога указује се на везу између Западнога Балкана са популацијом с високом BAL компонентом и током BA.
Оur IBD results might recapitulate a network of long-term, recurrent genetic exchange between Pannonia/the Northern Balkans and the ancestors of the SP population in Eastern Europe (Fig. S32b), agreeing with the occurrence of high-BAL-ancestry outlier individuals (>50% BAL ancestry) in these regions since the Bronze Age (Fig. S33, e.g. I13170 (Montenegro_IA), I18183 (Hungary_IA_LaTene_o), I18721 (Croatia_MLBA), R3931.SG (Serbia_Viminacium_Roman_elite_1.SG), I20750 (Hungary_MBA_Fuzesabony), I12106 (Slovakia_IA_Vekerzug)). Without proper sampling of the Eastern Balkans, of Romania and Bulgaria, it remains speculative if these regions were part of this genetic network as well.
Genomes belonging to the Slavic Cluster can be identified in Pannonia and the western Balkans, specifically Croatia, Serbia and Montenegro, indicating a continuous presence of individuals with SP-related ancestry west of the Carpathians during the Roman Period, predating any later, large-scale migration.
Some of the earliest members of the SP cluster, dating 800 BCE to 200 BCE, are found in the Czech Republic, Hungary, Croatia, and Montenegro (Fig. S32b). The oldest individuals belonging to the SP cluster that also receive the majority of their ancestry from a Northeastern European-related source are an Iron Age individual from Montenegro (I13170), a Late Bronze Age individual (associated with the Knoviz culture) from the Czech Republic (I16089), and two Middle Late Bronze Age individuals from Croatia (I18721 and I18723).
