I'm not questioning previous results just pointing out that the situation becomes more complex the more closely I look.<br />"Macroscopically", if you run Europeans as Fertile Crescent versus Amerindian/Siberian there is little complication and results are straightforward I think.<br />The problems start when you want to differentiate between different "Mesopotamian" waves. And see the North African components, the Amerindian ones, and "Mesopotamian" ones all at once.<br />Different "Mesopotamian" subsets are admixed with each of these more exotic elements, and when they split, they tend to take some of it with them, or to become subsumed into them.<br />In order to differentiate more precisely different "Mesopotamian" and other elements in Europeans I would ideally use unadmixed modern populations corresponding to the ancient subsets. But these mostly don't exist anymore. For instance French Basques are almost fully "Mesopotamian core". But I now am seeing results suggesting even they have are composed of one dominant and another smaller "Mesopotamian" subset.<br />Things will become clearer with the next few posts.Diogeneshttps://www.blogger.com/profile/00827839380414245914noreply@blogger.comtag:blogger.com,1999:blog-6443268110928728533.post-41335678116247957412011-05-03T03:42:29.935+01:002011-05-03T03:42:29.935+01:00I do not fully understand what you mean by this.
...I do not fully understand what you mean by this.<br /><br />''With more populations, there are sufficient differences that ADMIXTURE tends to fall into lumping them with aboriginal/2nd wave smaller elements into artificial components. For instance the Siberian/Amerindian-like element of some North Europeans often disappears into the local MPC; the Nile Core of Southerners and especially Middle Easterners into their local varieties''<br /><br />Do you mean that the Siberian and Amerindian like components in some Europeans are subsumed or ''swallowed up'' by the larger MPC components?<br /><br />Are the Siberian and Amerindian components that have been shown in previous runs in many Europeans still real then?jackson_montgomery_devonihttps://www.blogger.com/profile/17553257488930856466noreply@blogger.com
