Hi Alex,
I was just reviewing Adriano's latest Y comparison spreadsheet and noticed that you recently submitted your 23andMe results to him. It appears that you have an unexpected SNP in your data -- you are the only E1b1b1 person on the spreadsheet who is positive at rs4988808, so far!
"New" SNPs like this are exactly what we are hoping to discover with Adriano's spreadsheet, as they have a good chance of defining new subclades. What's even more interesting about this SNP is that it already defines a completely different branch of the Y chromosome tree-- it's the defining mutation for haplogroup F. So, it appears that this SNP may have mutated two different times in history -- once to define haplogroup F and another to define a subclade of haplogroupE1b1b1.
