Yes it does make sen...@ jackson_montgomery_devoni <br /><br />Yes it does make sense and I assume that it ultimately originated in the Levant/Mesopotamia and moved first into Sardinian trough a sea root and from there moved further forward into Iberia (also trough sea) and later spread across Europe.Kurtihttps://www.blogger.com/profile/15370578131814705759noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-40157193557576827352012-09-18T12:26:14.043+03:002012-09-18T12:26:14.043+03:00"the Mediterranean element in Europe will be ..."the Mediterranean element in Europe will be confined totally to the circum Mediterranean and the Near East"<br /><br />I think it will spread up the Atlantic coast as well but in a different proportion.Greyhttps://www.blogger.com/profile/13398462488549380796noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-53025114001853199012012-09-17T13:15:44.916+03:002012-09-17T13:15:44.916+03:00"the North European element will be native to...<i>"the North European element will be native to Eurasia spread from the borders of Europe all the way to the borders of Mongolia...</i><br /><br />Ponto, <br /><br />I think admixture stretches back to and from the first European settlement until the Bronze Age and beyond. But I don't believe in endless unidirectional flows to the West. <br /><br />The Gravettian already had a very strong eastern component, and I tend to believe that the Franco-Cantabrian refugium had a stratified structure, with more NE people at the NE margin, who then would dominate post LGM NE expansion (NE Magdalanian), in addition to the existence of Eastern refugia (Moravia, Balkans, Crimea, Caucasus, Kazakhstan, Altai, etc.). To me, the Ahrensburg and Hamburg cultures also show Eastern influences - although only some of this means connection to Central or Eastern Asia (e.g., Western Kazakhstan is part of Europe...).<br /><br />Even without concrete flows of specific Eastern populations into Europe (but rather a 40,000 years shared heritage), it should be possible to disentangle this with better sampling in the respective regions, and future ancient DNA that should be expected from some of these colder and dryer regions.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-54280505353426459582012-09-17T09:43:54.569+03:002012-09-17T09:43:54.569+03:00It's not a spreadsheet, open with a text edito...It's not a spreadsheet, open with a text editor.<br /><br />@Matt<br /><br />There are 760380 possible f3(A; B,C) choices so this would take weeks to compute.<br /><br />Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-24276131694489096592012-09-17T05:47:21.965+03:002012-09-17T05:47:21.965+03:00I couldn't open your spreadsheet.

Unfortunately, the results are biased towards Europe excluding other regions, and from a young age, the border of the start of agriculture in the western and northern parts of Europe. Too biased.<br /><br />It is amusing that one other amateur wanted to exclude Sardinians, and Basques from Admixture runs because they skewed Northern and Central European results. My protest was that the Sardinians in particular showed the strongest affinity to me, the Tuscans also to a lesser degree. Excluding Sardinians just gave false results for circum Mediterranean peoples. Ascertainment bias producing calculator bias. Anyway, these things will be ironed out in the long run.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7785493.post-16759962736003305392012-09-16T23:47:58.552+03:002012-09-16T23:47:58.552+03:00I'm sure it would be computationally horrible ...I'm sure it would be computationally horrible and impractical, but this does make me wonder what the result of carrying out and exercise like http://dienekes.blogspot.co.uk/2012/09/inter-relationships-between-dodecad-k7b.html, where you <i>"count the number of times it appears before the semi-colon, and subtract the number of times it appears after the semi-colon"</i> would be repeated for your set of populations.Matthttps://www.blogger.com/profile/04517454865405705885noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-55316003754019153242012-09-16T22:31:36.833+03:002012-09-16T22:31:36.833+03:00Dienekes,
