De oudste fries stamt uit 2500 voor Christus en is in 1990 al gevonden in West Friesland.
Dit is hem, onze Cees:
Uit DNA-onderzoek bij Cees de Stenentijdman gevonden in 1990 in Mienakker NH (zie: https://collectie.huisvanhilde.nl/pdf/publieksbrochure_steentijdman.pdf ) blijkt hij de haplogroep R-U106 te hebben. Zie dit onderzoek: https://www.biorxiv.org/content/10.1101/2025.03.24.644985v1.full
Rond 4500 jaar geleden was er een influx van mannelijke Corded Ware (Yamnaya) personen welke mixten met de al aanwezige vrouwelijke Western Hunter Gatherers om lokaal tot de nieuwe Bell Beaker cultuur te leiden. Tussen die mannelijke immigranten zaten ook R1b-U106 mannen waaronder Cees of een van zijn voorvaderen. Deze haplogroep R-U106 ontstond rond 3000 voor Christus en is nu nog steeds het sterkst geconcentreerd in het huidige friesland (en vroeger het grotere Frisia met naast Midden, ook West, Oost en Noord Friesland) en heeft ook het hoogste voorkomen onder de huidige friezen.
Het lijkt er dus sterk op dat de friezen al zeker 4500 jaar onafgebroken in friesland woonachtig zijn. Leuke citaten: We find that the earliest Neolithic individuals (4400-3800 BCE), associated with the Swifterbant culture, are genetically highly heterogeneous, with a mother and her daughter (I12093-I12094; Nieuwegein) entirely descending from hunter-gatherer populations Despite a low steppe ancestry proportion in the autosomes, the male I12902 from Mienakker, who yields one of the earliest CW complex associated dates on bone in Europe outside of Bohemia and the Baltic region (2852-2574 cal BCE), carries Y haplogroup R1b-U106, also known in one early CW-associated individual from Bohemia7. These results suggest that the male ancestor who brought this Y haplogroup to the Rhine-Meuse region was part of the early CW expansion. While limited to three people, the IBD analysis for the Vlaardingen/CW individuals revealed two additional notable signals. First, the two individuals with 11% CW ancestry, excavated at nearby sites, have an IBD match that represents approximately a 3rd cousin relation, hinting at a small community size. Second, the geographical range of their IBD links extends much further east than previous groups (Extended Data Figure 1). Among their closest connections (one segment of 19cM) is a Yamnaya-associated individual from Samara in far eastern Europe59 (ID: I6733) and CW-associated individuals from present-day Poland60 (ID: pcw362) and Czechia7 (ID: STD002). We also detect connections to other Rhine-Meuse area Late Neolithic individuals, providing direct evidence of a major local ancestry component in Vlaardingen/CW individuals. These patterns reflect their dual sources of ancestry: a minor component (potentially completely along the male line) from central/eastern CW groups (and through them to Yamnaya steppe pastoralists) and a major component from the local Neolithic population. By the Early Bronze Age, when ancestry proportions in Britain stabilized, we estimate 91% Rhine-Meuse BB ancestry and at most 9% local British Neolithic ancestry but possibly as little as 0%, providing new information about the magnitude of the demographic transition associated with the BB transition in Britain.
