This study attempts to establish which of modern ethnic groups (18 were examined) are descendants of inhabitants of Iron Age Poland and of Early Medieval (first Piast dynasty rulers) Poland. The study compares samples of fossil mtDNA from Late Iron Age Poland (200 BC - 500 AD) and Early Medieval Poland (950 AD - 1250 AD), with samples of mtDNA from modern populations. Sample sizes are 23 individuals from 4 burial sites of Ancient Poland and 20 individuals from 2 burial sites of Medieval Poland. These Ancient and Medieval samples were compared to a large modern sample of 3595 individuals from 18 ethnic groups (300 Poles, 305 Belarusians, 307 Russians, 300 Czechs & Slovaks, 300 Bosnians, Slovenians & Croatians, 300 Bulgarians, 293 Macedonians & Serbians, 300 Ukrainians, 296 Swedes, 300 Germans, 277 Lithuanians & Latvians, 317 Finns & Estonians).
Ancient burial sites are Kowalewko (K), Karczyn (KA), Gąski (G) and Rogowo (R) associated with Iron Age Przeworsk & Wielbark Cultures.
Medieval burial sites are Ostrów Lednicki (OL) and Cedynia (C), both associated with the reigns of Mieszko I and Bolesław I (960 - 1025).
Briefly, the results of the study can be described like this:
The highest % of shared informative mtDNA lineages with people of Iron Age Poland is among modern: Poles, Czechs, Slovaks, Lithuanians, Latvians.
The highest % of shared informative mtDNA lineages with people of Early Medieval Poland is among modern: Poles, Belarusians, Bulgarians, Ukrainians.
The lowest % of shared informative mtDNA lineages with people of Iron Age Poland is among modern: Macedonians, Serbs, Finns, Estonians, Germans.
Out of 18 examined modern ethnic groups, Poles appear to share the highest % of mtDNA with samples from both Ancient Poland and Medieval Poland. Modern Germans appear to share only little of informative mtDNA with Iron Age Poland (samples from 4 burial sites of Przeworsk and Wielbark Cultures). So Ancient amber traders along the Amber Road were not ancestors of Germans. The study confirms continuity of many lineages between those traders and modern Poles. But it seems that there was also immigration of new lineages (similar to Bulgarians & East Slavs) between 400 AD and 900 AD.
