Originally posted by JuanCarlos View PostHis results are interesting, to say the least, since they provide a window into what may be the original genetic composition of people who are, or were, fully Native American. As we can see, that population already had North Circumpolar, which is European and mostly found in Finland, and Central/South-Asian-Eurasian Heartland combination, in addition to other components you would expect.
Ideally there should be one calculator for ancient events like these, and another one that reflects historical population movements in the last few hundred years (presumably most FTDNA customers are more interested in the latter). In practice it's hard to fully separate ancient and recent events, but the current MyOrigins seems to not even try.

Originally posted by robe3b View PostJosh and Rafael, having read your comments, I think I should clarify my previous ones. To me the real issue is not whether I have or have not any Ashkenazi Jewish ancestry; this is totally irrelevant to me, as the many Ashkenazi "cousins" I've found both on Family Finder and Gedmatch came out totally unexpected. Still, it seems I'm the one to be blamed for this misunderstandig, as I mixed percentages of Middle Eastern ancestry up with having surprisingly many Ashkenazi cousins. The issue here is the sharp differences in ancestry estimates between PF and myOrigins, from 14.38% to 1% Middle Eastern ethnic ancestry. I should add that the same thing has happened with my Native American percentage. PF gave me an astonishing high estimate of NA ethnic ancestry (36.4%); myOrigins has brought it down to 31% (23% Beringian Expansion plus 8% Asian Northeast. Anyway, I've decided to give FTDNA the benefice of the doubt; perhaps they're right now, and I really am 66% European (Mediterranean Basin, the whole of it), 31% NA, 1% Middle Eastern, 1% African and 1% unassigned). It makes sense, as I'm South American

Originally posted by Rafael Fernandes View PostAs I said previously, the fact that your Middle Eastern ancestry has fallen from the older program to the new one may be due to the fact that the older one's ability to measure Southern European ancestry was more limited. Population Finder was identifying many people from Southern Europe -- specially those of Italian or Greek ancestry -- as being as much as 50% Middle Eastern, for lacking samples that accurately represented their ancestry. In the case of people with Southern European blood, this may mean having inflated results in both the North European and Middle Eastern clusters because these are the ancestral components closest to the Southern European one. It was frequent to see a South Italian, for example, being guessed as 50% Western European and 50% Middle Eastern, or a Portuguese person being guessed as 80% Western European and 20% Mozabite. My results went through the same as yours, albeit less dramatically; my Middle Eastern percentage has fallen from 24% in PF to 16% in myOrigins, and I have little doubt that this is because of myOrigin's greater accuracy.

Originally posted by josh w. View PostNot sure if we fully understand the changes from PF to MO. Given the various migrations from the Near East and North Africa to southern Europe (Phoenicians, Moors--migrations might have begun before written history), there should be some sign of this migration among Mediterranean Europeans. Sephardic Jews might be subsumed under Northern Mediterranean with no mention of the Near East.Last edited by josh w.; 15 May 2014, 09:59 AM.

I suspect the underlying problem, or one of them, is that MyOrigins is still using very small numbers of samples for individual "populations". That is, a small number of samples does not seem sufficient to capture and represent the gene frequencies of the entire population of, say, Italy. While the samples surely capture some of the existing variation in their target populations, it seems to me that the small sample sizes will inevitably introduce a very large component of statistical noise into the percentage figures. The changes reported here, from the Population Finder to MyOrigins, are telling us something about the magnitude of the noise component. Maybe MyOrigins is more accurate in some sense, maybe not, and the magnitude of the discrepancy between the two algorithms should not be expected to affect everybody in the same way.
Is MyOrigins constructed in such a way that new reference samples can be added to the existing ones as they become available? An algorithm that adjusts itself as new data are added would seem to be the way forward.

Originally posted by josh w. View PostIt may be a function of when the admixture took place with earlier admixture being less apparent. Ashkenazis do not show a Northern Mediterranean component with MO even though it is quite evident in Dodecad and Eurogenes. Perhaps founder effects and genetic drift in Ashkenazis contributed to the MO oversimplification. MO and PF were not intended to give a complete picture--more like the #1 hunch from Oracle. The Oracle estimates derive from the full composites in Dodecad and Eurogenes

The Italian component was missing on PF; MO seems to have corrected this discrepancy.

To amplify on my last post. From the White Paper authorship, I might be incorrect but it appears that the Admixture pattern is computed by the Harrapa World program and then in a second step the best fit to the admixture pattern is estimated by an Oracle like program.

I find it odd that my mother has no European Coastal Plain in her MO. Harappa shows over 15% N.European and over 1% "American", which is believe is essentially N. Euro; every calculator at Gedmatch shows some N.E. for her.

The Italian (or Sardinian) component is always present; conversely, the Middle Eastern component almost never shows up.
