Haplogroup I-Z63.

The year 2600 BCE marks the estimated formation of Haplogroup I-Z63 according to genetic analysis by YFull. This calculation relies on volunteer samples from YDNA sequencing projects conducted in recent decades. The Time to Most Recent Common Ancestor for this lineage stands at approximately 4,400 years before present. Researchers place the geographic origin of the progenitor within ancient Jutland. A specific archaeological sample labeled CGG106524 provides physical evidence near Hjørring in Denmark. C14 dating places this individual's life between 400 and 220 BC during the pre-Roman Iron Age. The sample belongs to subclade PH3482 which formed roughly 2,800 years ago. Current distribution patterns suggest a very high concentration of this DNA on the British Isles today.
Archaeological Evidence And Distribution
Schleswig Rathausmarkt excavation in Germany yielded sample SWG007 from grave 179 dated between 1070 and 1140 CE. Stockholm University published data regarding six Viking Age samples found on Gotland island in the Baltic Sea. These samples belong to branch I-FT140572 which formed around 350 BCE. Five of these samples helped create new branch I-FTJ74 sharing two single nucleotide polymorphisms. Bodzia Cemetery in Poland contained burial E864/I belonging to subclade I-S2077 from circa 1010 to 1020 AD. Strontium analysis of teeth enamel indicates the buried man was not local to the region. Zeytinliada 14832 represents an adult living between 600 and 1000 CE near Erdek Turkey. Collegno Italy holds a late sixth century cemetery associated with Gothic and Lombard remains. Tiszafüred 798 in Hungary dates to between 700 and 800 CE under the Avar cultural group.
