I have heard many Arabs say it is an extension os Mesopotamia? Isn't this where the Elamites were settled? The Zagros was supposed to be a barrier to gene flow but it doesn't seem like iranians living West of the Zagros are any different from their Eastern counterparts does it?newtoboardhttps://www.blogger.com/profile/13713811322016152404noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-73815203649642845342012-02-10T06:18:50.362-08:002012-02-10T06:18:50.362-08:00I respectfully disagree with your first point in t...I respectfully disagree with your first point in this particular context. Removing African reference groups will not significantly effect scores of populations that are almost entirely Eurasian.<br /><br />The absence of San or Hadza in the latest run only coincides with the dissolution of the "Southern" component, which has likely consolidated itself into at least the Southwest Asian and Caucasus components. <br /><br />You are describing two separate changes from K9b->K12b. That does not necessarily mean one change led to the other. There may have been some intra-component consolidation once the San and Hadza were removed, but the difference is largely accounted for by the increased K=n. Components become unstable beyond a certain K value (as previous Dodecad iterations and the Harappa Project have shown in older posts).DMXXhttps://www.blogger.com/profile/16689998564656086919noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-1797444365222261062012-02-10T06:07:06.113-08:002012-02-10T06:07:06.113-08:00It is who you remove from the data set that makes ...It is who you remove from the data set that makes a difference, in other words the degree of genetic divergence that a given population has from the data set has a direct impact in which populations a cluster will appear/disappear in and the distribution for the remaining clusters, for instance removing the Chinese and keeping the Japanese in a global data set will have much less of an impact in the distribution of a fixed number clusters than removing the San and keeping the Yoruba in the same data set, since the San are as genetically different from a Yoruba as they are from a European. <br /><br />The world 9 global run, which included the SAN and the Hadza, had produced a cluster nick-named “Southern” that was very wide flung, from Northwest Africa to well into West Asia and from Subsaharan East Africa to Southern Europe, here below were what the populations outlined in the topic of your post had scored for the “Southern” Cluster:<br /><br />Iranian_Jews 43.3<br />Assyrian_D 41.3<br />Armenian_D 37.8<br />Armenians_Y 37.3<br />Armenians 33.2<br />Turkish_D 32<br />Kurds_Y 31<br />Kurd_D 30.8<br />Iranians 30.6<br />Turks 30.5<br />Iranian_D 27.4<br />Turkmens_Y 17.6<br />Tajiks_Y 9.4<br />Uzbeks 8.3<br />Uygur 5.5<br /><br />As you can see, this cluster has vanished however in the K12 run, had the same data set of 'World9' been run at the ADMIXTURE, K=12 level this cluster wouldn't simply have vanished.Etyopishttps://www.blogger.com/profile/17311733086301215105noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-4080077638646765912012-02-09T18:03:24.258-08:002012-02-09T18:03:24.258-08:00Thank you for your comment; I agree that the exclu...Thank you for your comment; I agree that the exclusion of reference populations from ADMIXTURE (such as the one you stated) will likely lead to a re-shuffling in certain components. However, as African-relevant components are present in trace quantities at best in this particular analysis, the exclusion of the San or Hadza will probably not lead to any significant differences.DMXXhttps://www.blogger.com/profile/16689998564656086919noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-2439995927537783862012-02-09T16:58:20.345-08:002012-02-09T16:58:20.345-08:00Hi, Nice blog.

Please take a look at the K9 global run for a relative comparison.<br />Thanks.Etyopishttps://www.blogger.com/profile/17311733086301215105noreply@blogger.com
