U3b2 was a genetic mutation of U3b, so just like ANY mtDNA line, it eventually gets back to mt "Eve".darkerhorse wrote: ↑05 Feb 2022, 23:16 In other words, it was brought to Sicily from some other place and then changed there.
Where U3b mutated into U3b2 is unknown, but it settled in those 4 places. That's why it's considered as "originating" there. My guess would be it likely mutated in Turkey (where other U3 haplotypes exist) and spread to Sicily, Hungary & possibly even Arabia from there.
When I did some investigating of the U3b2 subclade, about 75% of the examples (currently living people) trace their ancestry back to Sicily. It's uncommon even in those other 3 locations & only makes up about 3% of the Sicilian population. So it's extremely uncommon.
Between that and the ethnicity mixes indicating at least some Sicilian, I have to connect those dots. Although I do have the West Asian mix also, it only averages about 1-2% of the total (2-4% of the Italian half).
Also be aware that at least some northern NA ancestries resemble those of Scandinavia and even Northern Russia.
