    C and F about 72kya
    D and E about 69kya
    Well within the intervals of the new study.

    If Basal Eurasian exists, it hasn't left any super-basal lineages in it's descendant populations.
    More likely to be chocked up as E or maybe G.
    I think we should expect somewhere down the line or in that particular instance, that many populations for whom we have austosomal descendants have had their ydna completely washed out. And at some point the same may have happened to their mtdna lines as well. This can be similar to the processes that removed such mtdna and even ychromosomal neanderthal ancestry - but with different causes seemingly. So I don't think every population we see should be invalidated or not by whether they have any ydna or mtdna that can be in any way possibly derived from them in present day or any later populations. Not to mention what the seemingly infinite possibilities borne out of any hint of auDNA turnover. Their are too many possibilities to link ydna or mtdna with a specific population due to such autosomal turnover being very quick for human lineages, where original populations ancestral to those very lineages not being found anywhere in the autosome, and can take place in the space of 3,000 years or less. And We're speaking in the tens of thousands and up to 300,000, 100,000, 50,000, and 60,000. And seeing how unexpected our much more densely studied and predictable 10,000 year post-Neolithic window of aDNA findings are, I find myself expecting the most unexpected for anything concerning human ancestry at those ages. We're already speaking of superarchaics, whether A00 may from another parallel species, and Neanderthal mtdna and/or ydna being introgressed from more basal and more HSS lineages.

    Which is why I ultimately only put my faith in ancient dna. But sometimes, as with the Ibermaurusians - it only serves to make things more confusing and muddied.

    Some interesting stuff from the link you posted - just so everyone can understand the relation between the Syrian (ftdna), Saudis (ftdna) and the 3 Nigerians (Haber et al.):

    Haplogroup-D-Family-Tree-DNA-diagram.png

    So the Syrian is "basal" (i.e. earlier split) to the lineage (D0a or D2a) that leads to the Saudis and Nigerians.

    Most interesting of all is that these samples are D2, which has hitherto only been found in the Philippines. Amazing how such a small, ancient lineage is found on nearly polar opposite corners of the world.

    The Filipino D is M174+, so it should be reclassified as D1b.

    Is he the YF03778 kit on YFull? Are there any other confirmed D2s?

    Yes he's the M174+ "D2" I was talking about. It's probably the same clade as the "D2" defined by isogg.

    Yes, but ISOGG has two separate subclades, D2a and D2b, so presumably they must have some other sample(s) than the guy already on YFull, no?

    Yeah they are relying on other samples from some paper - but you can be sure those are also from Philippines - check the "geographic distribution" section in isogg site for D.

    So you're assuming the other D2 samples would fall under the same clade as the M174+ YFull guy? Is there any way we can get a hold of the samples from ISOGG?
