Visualizing admixture differences with ACD tool

Vaêdhya has created a new ACD tool that allows one to visualize differences between sets of populations in terms of admixture components. He also posts two examples of the application of his tool on data generated by myself in the Dodecad Project, as well as by the Harappa Project.

 I have speculated about the origins of Indo-Iranians before, noting that the evidence links even the Kurds with a "South Asian" component; in subsequent higher-resolution analysis, such as the K12b, it appeared that this component was related to the Gedrosia component. In any case, the evidence is clear about the links of different Iranian and Indo-Aryan groups, so it is nice that this can be made evident with the ACD tool and data from the Harappa Project. Notice the excess of the Baloch (~Gedrosia) component in Kurds and Iranians in contradistinction to the Indo-European Armenians and Semitic Assyrians. It is fairly clear to me that the Iranian ancestral homeland is to be sought to the east, with the Bactria-Margiana Archaeological Complex (BMAC) being a good candidate for its location.

In a second plot, Vaêdhya uses Dodecad data to contrast patterns of differences in Northeastern Europe. Here, too, the patterns are clear, with Finns, and secondarily Russians showing an excess of Siberian ancestry relative to Poles. This is, no doubt, due to the Finnic element, which links Finns, and the Uralic substratum in Russians with Siberia. A second contrast is between Finns and Russians/Poles. The latter have more of the Caucasus component, a probable legacy of the Bronze Age Indo-European invasion of Europe. A final contrast is the higher Atlantic_Med element in Poles, which suggests an excess of early Neolithic farmer ancestry, or, admixture with West European populations such as Germans and others who possess more of this component than Slavs.
