"The Sephardim are a major Jewish ethnic division whose origins can be traced back to the IberianPeninsula. We used genome-wide SNP data to investigate the degree of Sephardic admixture inseven populations from the Iberian Peninsula and surrounding regions in the aftermath of theirreligious persecution starting in the late 14th century. To this end, we used Eastern Mediterranean(from South Italy, Greece and Israel) and North African (Tunisian and Moroccan) populations asproxies for the major ancestral components found in the target populations and carried out unlinkedandlinked-marker analyses on the available genetic data. We report evidence of Sephardic ancestryin some of our Iberian samples, as well as in North Italy and Tunisia. We find the Sephardicadmixture to be more recent relative to the Berber admixture following an out-of-Iberia geographicdispersal, suggesting Sephardic gene flow from Spain outwards. We also report some of thechallenges in assigning Sephardic ancestry to potentially admixed individuals due to the lack of aclear genetic signature."

I stopped reading at page ten because I was completely unconvinced. Are there shared alleles between Iberian groups, some North African groups, the southern French, Italians, and Cretans on the one hand and the Sephardic Jews on the other hand? Of course there are.
Does that mean that the shared genes are because of Sephardic Jewish intrusion into these other areas following their diaspora?
I don't see how you could possibly say that, or at least how you could know the percentages.
The similarities could go back to similar ancestral inputs into all these groups going back thousands of years. Plus, if some papers are correct and Ashkenazim are the result of Middle Eastern Jewish men marrying Italian women, a similar process could have gone on in Spain, and therefore the gene flow could be to some degree from Iberians into Jews.
They should have known this. If they didn't know it ahead of time, the hint should have come from the closer sharing they're seeing with the people of Crete. Now there was a huge influx of Sephardim specifically into Crete? Enough for those kinds of percentages?
Or, why didn't caution set in when they saw percentages in Berbers for "Sephardi" admixture which they acknowledge are way too high? No, they're thinking Phoenicians/Carthaginians might have had an input. You'd think this was written by anthrotards. What about the simple explanation which is that the Jews picked up Maghrebi ancestry from their stay in North Africa before they went to Iberia? That's probably where they get their SSA after all.
I also find it amusing that they acknowledge the strictures against intermarriage, but don't seem to apply it to the situation in Europe. I don't know why it didn't dawn on anyone that the whole reason that they left Iberia was because they didn't WANT to convert. So, they leave behind their homes, their landscapes, their businesses and money, go to a foreign land, all so as not to convert, and then to marry "gentiles" and admix, they convert???
I'd also love to know why they didn't include the Dutch, with their big Sephardi community.
Anyway, maybe they did address some of these things later in the paper. I just lost patience and stopped reading. Some of these groups are going to have to up their game.
Also, very surprised Razib Khan signed on to this, albeit only from the abstract. He should know better.
