    Thanks a lot for explaining this in detail. Are you sure the totality of West Asian goes to Japanese though?

    By the way here's what some ancient genomes score on this, notice how Satsurblia only gets 18% Japanese :

    No, I am not sure of the complete breakdown - but it is splitting things up at an extremely low level for non-African components. I was doing some quick analysis to try to stop the inevitable wave of "this calculator sucks" comments when folks just aren't reading how it was designed and its purpose. I would think some of the Asian admixture closer to West Eurasian may be going to North African and maybe even some African (like the Omotic component, possibly). So, I was just reporting what was happening based on the some screen-painted segments in my chromosomes that showed as almost all "Japanese" and then looking at a higher-K calculator with more "global" components to see what that calculator reported for that same area. In each case, there was a lot of East Asian, South Asian, Southwest Asian, West Asian, and Amerindian components in that segment.

    I would venture to say that part of the West Eurasian is reading as "East Asian" in addition to "North African" on the basis that North Africans are somewhat distinct from other West-Eurasians. North African components often include additional SSA or something else divergent relative to other West Eurasians IIRC. The result for this calculator being: the remainder West Eurasian not read as "North African" reads as "East Eurasian." Hope that makes sense.

    Yes, I was just replying something very similar when you must have been writing this.

    This is a reasonable explanation, but then why would an unadmixed European ancient genome like that of an Anatolian farmer score 85% North African? To say it better, if the algorithm can read as much as 85% of the genome as " African", what prevents it from reading the rest as such ? To me the obvious explanation is that for some reason, this 15% is more similar to Japanese genomes, and it could either come from East Eurasian gene flow, or simply from undiferrentiated proto-Eurasian genes.

    Folks, glancing over the results, this calculator is clearly not designed to estimate E Eurasian ancestry for most members, as there does not appear to be any logical pattern.....

    If I have some time this weekend, I will put together a low K (k<6) calculator with proper Basal, W and E Eurasian references, that will give much more accurate and consistent results for those addicted to admixture calculators
