Please go back to the La Braña one: http://forwhattheywereweare.blogspot.com/2012/06/more-north-iberian-epipaleolithic-mtdna.html<br /><br />Dienekes first identified it as NW African, what seems to make sense but either we have to admit that there was NW African ancestry in West Iberia at frequencies similar, or rather higher, as those of today already in the Paleolithic, or we have to think that Bra is Neolithic in fact.

In the Chromopainter mutation count file they show increased mutations counts vs other populations. As a result they show far higher diversity than most European modern populations. This also result in a African like Paint vs donate profile of the La Braña vs other European populations.<br />ReplyDeleteAnders Pålsenhttps://www.blogger.com/profile/13444056522800105747noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-29378009850544406452013-06-24T21:58:45.047+02:002013-06-24T21:58:45.047+02:00This comment has been removed by the author.Anders Pålsenhttps://www.blogger.com/profile/13444056522800105747noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-9906014161772415052013-06-24T21:40:01.937+02:002013-06-24T21:40:01.937+02:00We don't even know for sure if that admixture ...We don't even know for sure if that admixture is African or Asian (or something else). Whatever the case Chromopainter goes chunk by chunk, so that part won't weight more than it actually weights (c. 10%). It seems that Braña can be largely (not much more than 50% in any case) with other European donors but it does not paint them almost, so... well, just some sort of unclear relationship. The sequence is in any case too short, and composite of two individuals, maybe not even related, to be too informative. We can't waste so much time discussing something so evasive.

This is sim...Anders PålsenJune 24, 2013 at 8:10 PM<br /><br />This is simply because of the African minority admixture in the La Braña, you see it it the mutation output file from Chromopainter where the differenational is high. Its not at the same rate as original Africans like Pygmys, San and Yoruba but still considerable.<br /><br />Maju wrote "being also a very weak donor but a rather strong receptor"<br />Anders Pålsenhttps://www.blogger.com/profile/13444056522800105747noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-63551208181286949372013-06-24T20:10:52.831+02:002013-06-24T20:10:52.831+02:00This comment has been removed by the author.Anders Pålsenhttps://www.blogger.com/profile/13444056522800105747noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-76791637914210363862013-06-24T20:02:32.038+02:002013-06-24T20:02:32.038+02:00Did it.

The (relatively) strongest Bra donations are to two individuals, one Estonian and the other Lithuanian. Still I would like to see CP comparison with wider populations (he mentions "Basques" but I suspect it a Google Translate error: "басками" is not quite like "баскский", which is what Wikitionary finds as "Basque" in Russian, maybe Bashkirs?)<br /><br />It seems that Bra just refuses to allow classification at autosomal level. Best to wait for future sequences IMO. <br /><br />Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-23410801613458382422013-06-24T18:53:47.036+02:002013-06-24T18:53:47.036+02:00Dienekes didnt have much samples from the far Nort...Dienekes didnt have much samples from the far North and he didnt have 68k markers neither when creating his calculator.

It did not seem much novelty after what was discussed <a href="http://forwhattheywereweare.blogspot.com.es/2012/06/more-north-iberian-epipaleolithic-mtdna.html" rel="nofollow">here</a>, based mostly on Dienekes. <br /><br />Anyhow, we still can't be sure if the La Braña pair are Epipaleolithic or Neolithic: their dating is borderline, the cave not used before and the flexed burials are much more typical of Neolithic people. <br /><br />Besides I don't understand well Chromopainter and, if it has anything to do with TreeMix, as I believe, I'd rather not rely on it at all.
