www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009938;p=2Brought over from Egyptsearch The genetic formation of Central and South Asian populations has been unclear because of an absence of ancient DNA. To address this gap, we generated genome-wide data from 362 ancient individuals, including the first from eastern Iran, Turan (Uzbekistan, Turkmenistan, and Tajikistan), Bronze Age Kazakhstan, and South Asia. Our data reveal a complex set of genetic sources that ultimately combined to form the ancestry of South Asians today. We document a southward spread of genetic ancestry from the Eurasian Steppe, correlating with the archaeologically known expansion of pastoralist sites from the Steppe to Turan in the Middle Bronze Age (2300-1500 BCE). These Steppe communities mixed genetically with peoples of the Bactria Margiana Archaeological Complex (BMAC) whom they encountered in Turan (primarily descendants of earlier agriculturalists of Iran), but there is no evidence that the main BMAC population contributed genetically to later South Asians. Instead, Steppe communities integrated farther south throughout the 2nd millennium BCE, and we show that they mixed with a more southern population that we document at multiple sites as outlier individuals exhibiting a distinctive mixture of ancestry related to Iranian agriculturalists and South Asian hunter-gathers. We call this group Indus Periphery because they were found at sites in cultural contact with the Indus Valley Civilization (IVC) and along its northern fringe, and also because they were genetically similar to post-IVC groups in the Swat Valley of Pakistan. By co-analyzing ancient DNA and genomic data from diverse present-day South Asians, we show that Indus Periphery-related people are the single most important source of ancestry in South Asia — consistent with the idea that the Indus Periphery individuals are providing us with the first direct look at the ancestry of peoples of the IVC — and we develop a model for the formation of present-day South Asians in terms of the temporally and geographically proximate sources of Indus Periphery-related, Steppe, and local South Asian hunter-gatherer-related ancestry. Our results show how ancestry from the Steppe genetically linked Europe and South Asia in the Bronze Age, and identifies the populations that almost certainly were responsible for spreading Indo-European languages across much of Eurasia[/QUOTE] www.biorxiv.org/content/early/2018/03/31/292581 But here's the thing from the study that really caught my attention and where people on the other site were acting dissimulated... Here we see the iron age samples from South Asia showing some E1b.

Really??? Africans in the Harrapan Valley? "The E1b samples are E1b1aE-Z6019 & Z6006 <-- Both primarily senegambian These haplogroups and E1a/M33 generally travel together.with this" "The study looked contained but if these samples lack respectable contemporary SSA Affinity we're in for a treat, if they do have SSA affinity then the story is simple Africans were in SW Asia. The fact that we have BOTH E1a and E1b there, leads me to believe that this was pretty direct. But IDK... maybe Djehuti & Lioness can add historical context" and DNATribes analysis From DNATribes(April 2014)- quote:: ==== Ancient Eurasian and African Ancestry in Europe Background: New Genomes from Ancient Europe Recently published ancient genomes from Europe, Siberia, and North America have provided new insights about the early migrations that have shaped the genetic structure of Europe. In particular, a new tree analysis of Eurasian population history models modern Europeans as a mixture of at least three ancient populations: Early European Farmers (EEF), Western European Hunter-Gatherers (WHG), Ancient North Eurasians (ANE), and Eastern Non-Africans (ENA).2 Some of these ancient populations (such as WHG hunter-gatherers) did not leave genomic traces outside of Europe; other ancient populations (such as the EEF “First Farmers”) left traces across a wider range of territories in both Europe and the Middle East (illustrated in Figure 1). Within this agricultural zone range, EEF farmers came in contact with other ancient populations: In Europe and West Asia, EEF populations mixed with North Eurasians (including Siberian relatives of WHG hunter-gatherers). In the Arabian Peninsula, EEF farmers mixed with ancestral Sub-Saharan Africans RELATED to modern Nigerian, Gambian, and Botswanan populations. In Armenia and Georgia, EEF farmers mixed with South Asian (Indian Subcontinent) populations.

Charlie Bass. I have this covered. Behar et al has shown African presence (genetically) all the way to Jews in China. OP, on African E1b, This is not surprising. These are not "Jews" in China but remnants of the Neolithics. The most DOMINANT and populous haplogroup in the IA peoples carry African haplogroup. lol! Where is Dr Winters? My Point on DNATribes? Lucas Martin had this figured out 4 years ago!!

You NEGROS really amaze me!! The elephant in the room.
Quote from the study: "we show that Indus Periphery-related people are the single most important source of ancestry in South Asia — consistent with the idea that the Indus Periphery individuals are providing us with the first direct look at the ancestry of peoples of the IVC — and we develop a model for the formation of present-day South Asians in terms of the temporally and geographically proximate sources of Indus Periphery-related, Steppe, and local South Asian hunter-gatherer-related ancestry. Our results show how ancestry from the Steppe genetically linked Europe and South Asia in the Bronze Age, and identifies the populations that almost certainly were responsible for spreading Indo-European languages across much of Eurasia."
If we take yDNA G and DE as African then that would make it nine(9) AFRICAN yDNA Haplogroup vs one(1) R1b. Yes, I repeat, one R1b. So how the F these are Euroasian Steppes migrants again? lol! What is wrong with you Negros?
There are more Africans in these samples than there are Europeans. So how did they conclude that the Indo-European language was NOT African again? SMH.

On OP. Pickrell had this covered egyptsearchreloaded.proboards.com/thread/1648/treemix-new-analytical-technique-dna Notice SSA has an event to South Asia. === I am now getting my head around this new analytical technique. I am under the impression that DNATribes is currently using a similar technique ======= Inference of Population Splits and Mixtures from Genome-Wide Allele Frequency Data - Joseph K. Pickrell (Nov2012) Author Summary However, it has long been recognized that, since populations from the same species exchange genes, simple bifurcating trees may be an incorrect representation of population histories. We have developed a method to address this issue, using a model which allows for both population splits and gene flow. In application to humans, we show that we are able to identify a number of both previously known and unknown episodes of gene flow in history, including gene flow into Cambodia We infer that the Mozabite are the result of admixture between an African and a Middle Eastern population (with about 33% of their ancestry from Africa), and that Middle Eastern populations also have African ancestry (Palestinians and Bedouins: w~13% from Africa; Druze: w~6%). This is consistent with previously reported admixture proportions from these populations [43,55]. Additionally, we identify the known European ancestry in the Maya (w~12%) [21], and infer that the Uyghur and Hazara populations are the result of admixture between west Eurasian and East Asian populations (w~46% and 47% from west Eurasia, respectively) [20,21,56]. Several additional migration events in the human data have not been previously examined in detail, but are consistent with previous clustering analysis of these populations [7,20,21]. These include migration from Africa to the Makrani and Brahui in Central Asia (w~5%) and from a population related to East Asians and Native Americans (which we interpret as likely Siberian) to Russia (w~11%). Two inferred edges were unexpected. First, perhaps the most surprising inference is that Cambodians trace about 16% of their ancestry to a population equally related to both Europeans and other East Asians (while the remaining 84% of their ancestry is related to other southeast Asians). This is partially consistent with clustering analyses, which indicate shared ancestry between Cambodians and central Asian populations [7]. To confirm that the Cambodians are admixed, we turned to less parameterized models. The predicted admixture event implies that allele frequencies in Cambodia are more similar to those in African populations than would be expected based on their East Asian ancestry. To test this, we used three-population tests [37]. We tested the trees [African, [Cambodian,Dai]] for evidence of admixture in the Cambodians (Methods). When using any African population, there is strong evidence of admixture (when using Yoruba, Z~{7:0 [p~1|10{12]; when using Mandenka, Z~{7:3 [p~1|10{12]; when using San, Z~{4:8 [p~8|10{7]). Finally, we infer an admixture edge from the Middle East ( a population related to the Mozabite, a Berber population from northern Africa) to southern European populations (w~22%). This migration edge is the one edge that is not consistent across independent runs of TreeMix on these data (Figure S8). In particular, an alternative graph (albeit with lower likelihood) places the Mozabite as an admixture between southern Europe and Africa (rather than the Middle East and Africa), and does not include an edge from the middle East to southern Europe. We thus hesitate to interpret this result, except to note that the relationship between northern African, the Middle East, and southern Europe involves complex patterns of gene flow that merit further investigation [43,57]. For example, in the human data, note that we see no evidence of the documented gene flow from Neandertals to all non-African populations [39] (Figure 3B). The reason for this is that the large number of populations with admixture can be accommodated in the tree by allowing the branch from Neandertals to Africans to be slightly underestimated (additionally, by using === What does it all mean? The researchers are getting really good at deciphering direction of migration. From the above they concluded “recent” Africans migrated to Cambodia, Bedouins, Druze, Makrani and Brahui(Harrapan Valley of India). For the Mozabite, they see evidence of North Africans to Europe. There ares also similarities between North Africans and some Middle East Populations. Thery are unsure on the direction. They are leaning towards the Saharan/Basal EEF as DNATribes. This is going to be a great year. A revealing year.

That’s right Oshun. Nothing personal between Swenet and I. We both know it. He is a big boy and he has some. Why don’t you grow some. That said, this has nothing to do with “throwing bones”. Yes, they have totally disregarding the African haplgroups in their conclusion but we should realize by now they have lost. Ignoring fundamentally AFRICAN haplogroups in South Asia is bordering on absurd now. They are frantically avoiding the elephant in the room. It is really hilarious when you read their conclusion/discussion and interpretations. Reich is “sticking to his story” at all cost. He is “going down with the ship”…eh Steppes. Lol! “That’s my story and I am sticking to it”. Theys guys got big egos and they will twist the data to suit their views regardless as to how ludcuors the hypotheisis is. Did you look at their migration map? It is too funny…like a spider web. GTFOH!!!! Steppes??!!
No Dr Reich (Lazaridis boss?) Sergi, DNATribes and xyyman got it correct. Neolithic Africans seems to be very late to the Harrapan Valley. As I said before regarding the haplogroups age. AMH, both waves, left Africa very recently.

You know I almost crapped myself looking at the data this morning. The idea came to my head that “did AMH originate in Asia and not Africa?”(Dienekes)…..This dataset is disturbing and all levels. Is that an A00(I6118) am I seeing in that packet that ELMaestro posted. Beyoku brought up the point about the Age. Should I go where the data takes me?
From the author
This is a first? "*****In the spirit of open science****,
"*****In the spirit of open science****, the authors of this study are inviting anyone who wishes to look carefully at this manuscript to write to us to let us know (a) if you find any errors, and (b) if you have any suggestions for changes that we could incorporate in the revision. We are also posting the data for the 362 newly reported ancient samples on our website and are open to suggestions for new analyses to include in our final submitted manuscript. If you wish to access the full analysis dataset including previously published samples some of which require a signed letter affirming certain conditions before for data release, please write to David Reich (reich@genetics.med.harvard.edu)"
from a commentor "Share › − Avatar Shi Huang • a day ago Why no discussion at all on Y and mtDNA data? May be something inconvenient? Why were Y chr haplotype A and BT so commonly found in ancient Turkmenistan (in supplementary table), when only CT are thought to have left Africa in the OOA model?"
so...do we have West Africans carrying A00 into the Indus Valley? This is getting good. He! HE! He! The shyte has really hit the fan.
@ed..yep, it is not a good year for Eurocentrics and those "pretending" to be AfroCentrics indeed.
To those who are into geography(remember I said genes always mimic geography or was it Sforza who said that?), anyways, Turkmenistan is NORTH of Iran/Persia. Meaning? 2000BC Obviously these Africans also occupied Iran. Right? Or maybe they “teleported” by-passing Persia. Keep in mind Persia is right connect to Yemen. Significance?

So some of these resreachers read the blogs....
from Davidski...on the paper.. "Lenny Dykstra said... No IVC samples....
Reich definitely got fed up with the Indians that had custodianship over those IVC samples, trying to contort the data to fit with an "Mesolithic North Indian Continuity" model or some such BS.
Reich releasing this paper without their input forces the hand of the would-be saboteurs. Now if they try to release an IVC paper without mentioning BA steppe input into modern Indians, or even more absurd they leave the door open for an Out of India IE model etc and then refuse to publicly release the sample data, then we'll all know the jig is up.
April 2, 2018 at 7:56 AM Blogger Nick Patterson (Broad) said... @lenny Dykstra:
I am extremely grateful to my South Asian collaborators (and this goes for the whole Reich lab.); they are honest, excellent scientists. There's a simple reason we have not published on DNA from the IVC proper -- we have no useful DNA, and as you might guess this is not from lack of trying.
Nick"
April 2, 2018 at 8:15 AM Blogger Mr Snow said... @nick Patterson Stop giving legitimacy to this garbage blog. Actually considering how your paper tried so hard to push a Kurganist agenda in spite of the data pointing to the contrary looks like you're a big fan of Davidski's delusions.
April 2, 2018 at 8:36 AM Blogger Dude ManBro said... Mr. Snow, really? You're going to insult an authority in the field because you don't like, what you assume to be, his interpretation of the data? C'mon, man...

public.tableau.com/profile/vagheesh#!/vizhome/TheGenomicFormationofSouthandCentralAsia/Fig_1 To those who are confused(ahem! Oshun) and wondering what is going on here? What ? where? and when? These samples are not really of the Indus Valley Civilization from my understanding BUT we can infer based upon.. WHEN the samples represent WHERE the samples were taken, WHAT were the haplogroups …and of course WHO WHO were the samples. Elite or l lumpenproletariat? What was the dominant haplogroup arriving in the area immediately before, during and near the IVC

So do we have another Luxmanda in Persia 2500BCE? Luxmanda carried African mtDNA L2a with 60% "Eurasian" ancestry. Or do we have Abusir with "Eurasian" ancestry and no SSA lineage..keeping in mind Gonur samples carried DEEP African lineage A0(0)? Can't get more African or deep than A00. Right? Did AMH originate in Asia?
They don't mention it because it will mess up their hypothesis and delusion. I am surprise it was actually published. But they did say.."in the interest of science" or something like that, they are trying to come clean. I think. Now the cat is out the bag will this trend continue? Will they continue to come clean? Although I do find it odd that no mtDNA L was found in prehistoric Persian region but yDNA A and E/PN2 is present. Did the African mtDNA L come later? Also why would E-M2 be present in pre-historic North Africa and Persian region and not be in Europe. We know the Sub-Saharan Sickle Trait/Genes are in Indus Valley , Greece, southern Europe etc. So where are the matching haplogroups? Logic is a bitch ........to dogma

Oh! I don't think the Mbo people migrated to Turmenistan....Geographically ...nah! It is more likely we are back to Sudan who also carry a high frequency of yDNA A albeit not A00...not discovered ..yet. Quote " E1a is a much neglected haplogroup.". This I agree with. IIRC E1a has been isolated in certain Italian populations. Dating back to pre-history. Sources cited(ED?). African haplogroups in the paper. I believe E1b1b* is expected but YDNA A(ancient) and E1a is a shocker in the modern population. E1a is also a very African haplogroup. Race is not we make it out to be. Irula of Indo/Pak
