They are highly skewed there.<br /><br />By excluding Kashmiri Pandit and Sindhi and agreeing that they are close to CEU yourself made your argument week. <br /><br />Of the 20 samples in the list Sindhi, meghaval and Srivastava are the only other north Indian Samples.<br /><br />Geographically West Asia is closest so genetic flow either way is not surprising. Whoever has more diversity that is the direction of gene flow.<br /><br />All these populations you sampled from India(South) you can see the actual data with high Y R2, and mt M. <br /><br />You should plot the graph with real north Indian populations.South Central Haplohttps://www.blogger.com/profile/00916788636469000041noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-23814189439538416062011-05-07T21:37:06.859+03:002011-05-07T21:37:06.859+03:00The Caspian horse isn't a wild animal, it'...The Caspian horse isn't a wild animal, it's one of the oldest domesticated horse breeds in existence. The paper on its genetic diversity calculates admixture estimates using the Caspian Horse as the eastern refugium contributor, and these are very high even for British and Iberian horses that also show evidence for the secondary domestication center. Diversity of eastern European horse breeds is lower than in the Caspian horse, of course someone can use that as evidence that horses were domesticated in eastern Europe, but using the same kind of "logic" we would conclude that the lowest diversity areas point to the area of domestication, so wheat, barley, sheep, oxen, etc. were all domesticated in Europe and not the Middle East.<br /><br />The only thing that remains to be seen is whether Russian or Central Asian horse breeds exceed the Caspian in diversity. Time will tell. Central Europe is out, however.<br /><br />It is important to note that the Caspian Horse does not have steppe antescendents, it is derived from the E. ferus populations of the Middle East. Its high diversity, its discovery in an early Iranian context, and its continued use down to the historical period in a a ceremonial and symbolic context is strongly inconsistent with the idea that "steppe pastoralists" introduced horses to Iran.Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-25715415228237026092011-05-07T21:18:51.326+03:002011-05-07T21:18:51.326+03:00"What pray tell is a CEU?"
"CEU&qu..."What pray tell is a CEU?"<br /><br />"CEU" is a pretty widespread used term on various DNA related websites and Forums.<br /><br />Dienekes most often uses "White Uthan" instead, wich I never read anywhere else but in fact describes much better what it actually is.<br /><br />"CEU" are white Americans from the state of Utah.<br /><br />Utah is known for mainly beeing settled by Brits, Scandinavians and Germans. Thats why "CEU" is often enough used as a proxy for a "Northwest European".<br /><br />These "CEU" however are kind of strange. I have seen numbers in wich North-Germans are closer to CEU than to Southgermans. While Southgermans are aswell closer to CEU than to Northgermans.<br /><br />In Dienekes exoeriments the current state is, that the only Europeans, still clustering with the CEU are the Brits. While Scandinavians and Germans seperated already.Fantyhttps://www.blogger.com/profile/07969348276219179258noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-84519745925666725632011-05-07T18:16:27.772+03:002011-05-07T18:16:27.772+03:00I am dubious about how these components are defin...I am dubious about how these components are defined.If you defined an Indus component,it probably show a spread all over Euroasia,real or imagined.simonhttps://www.blogger.com/profile/07163467514989396620noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-72148934635436368542011-05-07T15:16:16.259+03:002011-05-07T15:16:16.259+03:00One of the difficulies in reading your site is you...One of the difficulies in reading your site is your use of undefined acronyms.<br /><br />What pray tell is a CEU? <br /><br />I assume you mean central Eurasian. However, this acronym is not defined in any of your posts on the ANI.<br /><br />When I advised graduate students, I told them that in every paper one first spelled out the phrase and then but the abbreviation in parentheses after it. One could then use the abbreviation in place of the phrase. <br /><br />I always insisted that they do this for even the most widely understood abbreviations, because there will always be a first time reader who doesn't know all the standard ones.<br /><br />Unless of course, you're running a closed club with secret handshakes.sykes.1https://www.blogger.com/profile/10954672321945289871noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-22683066447724693342011-05-07T14:18:00.538+03:002011-05-07T14:18:00.538+03:001/ Iranians had possibly received an archaic Europ...1/ Iranians had possibly received an archaic European input (one example: for instance, the Zarzian culture might be related to eastern Gravettian culture that apparently arrived via the north of the caucasus, maybe before 15,000 BCE). Your former Autosomal data could also support it as the Iranian profile's "European" components have differences in size of the diverse components than in south/central/east Asia).<br /><br />2/ How comes the (mainly) north-west Indians share a mutation for lactase persistence (the -13,910 C>T allele) that the <b>west Asian</b> populations totally lack but that is very frequent among the <b>Europeans</b>? (http://www.biomedcentral.com/1471-2148/10/36/ in fig. 3). <br /><br />3/ And it's also weird that <i>saraswathy et al, 2010</i> (<i>"Brief communication: Allelic and haplotypic structure at the DRD2 locus among five North Indian caste populations"</i>) show the population of the north indian high castes as quite close to the populations of (north-)eastern Europe (such as Russian and Chuvashs) in his study (http://www.ncbi.nlm.nih.gov/pubmed/20091846). These populations that are actually living in the region of the Abashevo culture which is a proposed location of origin for proto-indo-iranian language by several scholars. Strange coincidence. <br /><br />It seems to go against it.wagghttps://www.blogger.com/profile/13582568982610797947noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-47378638205018518012011-05-07T13:08:58.246+03:002011-05-07T13:08:58.246+03:00I am still worried that these kind of studies can&...I am still worried that these kind of studies can't distinguish between recent (i.e., neolithic) and ancient relations.<br /><br />I know it's for some reason not very popular, but suppose for a moment that northern Indians and Pakistani populations were, as expected from climate studies, separated from the south by many tens of millennia starting from the initial population of the subcontinent, due to severe drought and absence of a monsoon. Then, most West Asian <i>and</i> European populations may very well originate from this northern portion of the sub-continent population, which could only re-unite with the south after LGM (when climate removed the large in-between desert areas, there).<br /><br />So, what I am saying is that a significant portion of the similarity between ANI and <i>both</i> West Asian and European may go back ~45,000 years.<br /><br />Then, only <i>that</i> portion of the signal which is exclusively West Asian is relevant to the neolithic. From that alone, I would concentrate on northern European populations that have the least known West Asian admixture. And I also would not be surprised that even for such Northern European populations with very little (neolithic) West Asian admixture, there is a remaining 20% - 30% affinity to ANI.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-76454514144391563832011-05-07T12:49:35.369+03:002011-05-07T12:49:35.369+03:00"Off topic" well i am discarding what yo..."Off topic" well i am discarding what you are trying to prove(in disguise) via your experiments! You are smart but hey where is the undisputable clue for your west eurasians, east eurasians and north europeans coming to india and creating vedic culture?<br />You are trying to prove that europeans dont have ASI component, but even Reich et al. Have said ASI is not related to any other population in the world! So<br />1. ANI and ASI mix is only possible in india.<br /><br />2. You said that if ANI is present in india from 45000 y.b. Then why europeans dont have the ASI component? <br />Ans: its simple, one branch of the ANI left india way before any mixing and created the bulk of the european peep's , while the other stayed home and later mixed with the 'blocked in india' ASI people.<br />According to oppenheimer r1a1a* did populated the eurasia from indian subcontinent 30000 years ago.Nirjhar999https://www.blogger.com/profile/00311196384969263463noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-33875182808393522072011-05-07T12:35:53.251+03:002011-05-07T12:35:53.251+03:00In case you missed it, the experiment was first do...<i>In case you missed it, the experiment was first done with Adygei who are about the most distant West Asian population you can find (genetically, they are technically European).</i><br /><br />If you compared West Asians, South Asians and, say, Africans, I would agree with you.

You don't have to be a biologist specializing in horses to understand that higher genetic diversity in animals points to wild expansion zones.<br /><br />On the other hand, lower diversity, with high frequecies of certain haplotypes, points to domesticated expansion events.<br /><br />So the Caspian area is likely a wild horse expansion region, but wild horses didn't speak Indo-European.Davidskihttps://www.blogger.com/profile/04637918905430604850noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-4892655059082093852011-05-07T11:18:09.797+03:002011-05-07T11:18:09.797+03:00I think you should repeat the experiment with diff...<i>I think you should repeat the experiment with different West Asian populations, as Iranians are geographically adjacent to South Asia and linguistically closely related to the IE speaking part of South Asia so they may be genetically much closer to South Asians than the average West Asian. </i><br /><br />In case you missed it, the experiment was first done with Adygei who are about the most distant West Asian population you can find (genetically, they are technically European).<br /><br /><i>LOL! again so what?
