I just wanted to point out that it seems logical that Germans (as a whole) would be quite diverse (given their geographical location), versus the belief that they are somehow an isolate and/or homogeneous.<br /><br />On the flip side, there is no question that there are numerous sub-regions within Germany (and within many other European countries) that indeed appear like small, homogeneous islands with relatively low outside exchange for perhaps millennia.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-56084430424600191892010-08-25T05:51:34.608+03:002010-08-25T05:51:34.608+03:00eurologist:

Also, it would certainly help if the the actual location (averaged over the four grand parents) would be used, rather than some country central value.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-85851855697448089472010-08-24T06:35:29.626+03:002010-08-24T06:35:29.626+03:00Hmmm.

And the folk who need this information as the people who don't know their origin and so don't know if they are admixed or not.<br /><br />The errors in the table can relate to the error in the model, or the degree to which the population is admixed. More admixed populations can expect to have more error.<br /><br />Which makes the results for the Germans and the Irish the weirdest, and interesting.
