What is the Origin and History of I1 M253

[Azzurro]

Why was that one line of snps in bold while the other ones weren’t? Also, was this sample positive for all 302 snps associated with I1?

For that you would need to ask Genetiker himself, he posts here every once in awhile. My understanding is that sample cannot be that specific clade because he is not positive for the ones above. I don’t think so but the sample was positive for a number of them, the TMRCA of all I1 carriers is 4600 ybp or 2600 BC, this individual is much before that date.

About 5000 years prior to the TMRCA. Perhaps the ancestors of Mr. DF29 were in Scandinavia shortly after the last ice age as opposed to entering with Corded Ware. Who knows!

That is a very plausible scenario! Actually seems to potentially be the case, the sample should be sent to Yfull to see if he’s ancestral to all I1 carriers.

Correlation does not imply causation but the I1 bottle neck and the Storegga Slide occurred roughly within the same ballpark time frame. Perhaps they were Doggerlandians (Doggerlandites?).
