[QUOTE]Originally posted by the lioness,: [QB] remarks form the "bruthas" who want to be European [QUOTE]Originally posted by Mike111: xyyman - please click on lioness link, and see for yourself how those genetic studies featuring "near distances" and other such nonsenses that you love so much, are used to complicate, and confuse, while offering nothing that can be of any use in understanding the subject. [/QUOTE]xyyman Mike doesn't undertstand this genetics stuff. It's all gibberish to him, maybe you can help his dumb ass [QUOTE]Originally posted by xyyman: My time is more valuable when I discuss the ORIGINAL study. [/QUOTE]You haven't read the original study since it's pay per view, only snippets from Dienekes. abstract and Suppliment, (food stamp money needed for food this month) [QUOTE]Originally posted by xyyman: Most of these bloggers repeat popular dogma. DNATribes is one of the few that does in-depth analysis because they have the tools to do it. [/QUOTE]DNA Tribes is a private for profit company that is not peer reviewed here is one of their maps> [IMG]http://www.ephotobay.com/image/picture-30-84.png[/IMG] here is the same map xyyman added his own blue arrows to> [qb] [QUOTE]Originally posted by xyyman: From Henn. She is basing this on autosomal SNP. This suggests that gene flow occurred from Africa to Europe rather than the other way around.[/b] DNATribes supports this view also. Basal Eurasian in Africa...YES!!! I can go on and on and on [IMG]http://i61.tinypic.com/2hibewj.jpg[/IMG] [/qb][/QUOTE] [QUOTE]Originally posted by xyyman: Even Dienekess is bi-polar. Just like the typical white male. I lurk at his site because he keeps up to date with the most current releases. I suspect he has the inside track on what is being researched and about to be published [/QUOTE]Below Dienekes; remarks on the thread topic paper, Genomic Diversity and Admixture Differs for Stone-Age Scandinavian Foragers and Farmers > . [i]"A new paper has just appeared in Science which adds new ancient Swedish hunter-gatherer samples, as well as a new Gökhem2 Swedish farmer. Much lower quality data from the same archaeological sites were studied in 2012 by much the same team, but the new study has sequenced several new Pitted Ware individuals from Ajvide, as well as a Mesolithic Swede. The Swedish hunter-gatherers appear to be similar to those of Lazaridis et al. (2013) in that their ancestry is a mixture of both European hunter-gatherers like LaBrana1 and ~15% of something related to MA1, which seems quite close to the 19% of ANE ancestry for the older Motala hunter-gatherer also from Sweden. The finding of Y-haplogroup I2a1 also parallels the Motala hunter-gatherers, so everything seems quite consistent with the Mesolithic Swedes being genetically very close to the Pitted Ware Neolithic ones. However, there is one difference in that the new hunter-gatherers were ancestral for SLC24A5 while the Motala one was derived (this is the "skin lightening" allele that was curiously missing in both Iberia and Luxembourg hunter-gatherers). The authors also find that the Iceman and Gökhem2 are a mixture of Basal Eurasians and something related to hunter-gatherers. A interesting new detail is that the Swedish farmer had more of the hunter-gatherer ancestry than the Iceman (the estimated difference in their non-Basal Eurasian ancestry is 77.2-56=21.2%) which seems reasonably close to the 16% difference in the related "Atlantic_Baltic" ancestry for the previous lower-quality Gok4 farmer and the Iceman I estimated in 2012. Finally, the authors also study the genetic diversity of the Swedish hunter-gatherers: [QUOTE] The Scandinavian Neolithic hunter-gatherer group had significantly lower conditional nucleotide diversity (0.181±0.0015) compared to the Scandinavian Neolithic farmer group (0.201±0.0038, Figs 3A and S9). While the specific properties of ancient DNA may still affect comparisons with sequence data from modern-day individuals, the conditional nucleotide diversity in the hunter-gatherers was also lower than in any modern-day European and a Chinese population (22) analyzed using the same approach as for the ancient groups.[/QUOTE]It is not easy to estimate nucleotide diversity with low coverage data (because you can't tell whether a sample is heterozygous in some position if you only have a handful of reads covering it), but the authors cleverly use the fact that they have multiple individuals from the hunter-gatherer population to estimate this. The low diversity in hunter-gatherers also parallels the finding of low genetic diversity in the Luxembourgeois Mesolithic hunter-gatherer, so it does seem that hunter-gatherers in Europe were a very low diversity population, which seems reasonable for people engaging in foraging (which does not allow for growth to large population numbers) and having ancestors who endured the Ice Age in Europe. The last few months have been extremely generous in new ancient DNA studies and I hope that more stuff is coming this year as in 2013. UPDATE: Also important (from the Independent): [QUOTE]“We see clear evidence that people from hunter-gatherer groups were incorporated into farming groups as they expanded across Europe. This might be clues towards something that happens also when agriculture spread to other parts of the world,” Dr Skoglund said.[/QUOTE]Science DOI: 10.1126/science.1253448 [/i] ______________ also note 48 comments on the comments link http://dienekes.blogspot.com/ Sometimes Clyde comments at this website [/QB][/QUOTE]
