The distances between populations in conventional PCA are significantly changed with this entropy based method. Hundreds of thousands of published admixture results could potentially be revised under this new method. <br />Link: https://arxiv.org/pdf/2303.12654.pdf<br /><br />Here’s an interesting finding regarding Latin American samples from the 1000 Genomes Project: <br /><br />“For example, for Puerto Ricans (PUR) and Colombians (CLM) conventional PCA spreads them along the beginning of the African cline, whereas rescaling shows them in the vicinity of other Latin American populations (Mexicans and Peruvians). Iranians, Turkish, Palestinian, Druze, French, Iberian (IBS), British (GBR), Russian, Finnish, Puerto Rican, and the majority of Colombians all form a much tighter cluster in the rescaled PCA, indicating that these populations are not as far from each other as the conventional PCA suggests.”<br />Thiernohttps://www.blogger.com/profile/13452118643827292940noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-57218113549097561842023-12-01T00:06:51.415+01:002023-12-01T00:06:51.415+01:00zz12_1/Z46512/S4381, BY11087, CTS3919, CTS8308/y23...zz12_1/Z46512/S4381, BY11087, CTS3919, CTS8308/y23651/ft86325/s4379 Igor Salazar (vitoria) sientete libre de contactarhombre de poca fehttps://www.blogger.com/profile/11996627723038013713noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-11505701776178888902023-10-29T19:33:18.936+01:002023-10-29T19:33:18.936+01:00Re.

This is almost certainly a Neolithic arrival via Sudan, whose genetics would need more study because they certainly have lots of Asian or even maybe European admixture, not just R1b (of unclear subclades) but even haplogroup I, which is otherwise believed to be exclusively Paleoeuropean.<br /><br />There was in any case Asian back-migration to NE Africa (and later to NW Africa from that region) with the arrival of Upper Paleolithic populations from West/Central Asia (ultimately from SE Asia via Northern India). This is strongly associated to the Upper Paleolithic or Late Stone Age blade technology. <br /><br />As for Middle Stone Age (Middle Paleolithic) it is strongly associated with Homo sapiens both in Africa and Asia. In fact it is the main fossil by which we know that modern humans migrated out of Africa into West Asia c. 125 Ka BP and into India soon after 100 Ka BP (probably also into SE Asia soon afterwards but we lack the stone tool evidence bc of the poor quality of that region's stone, which favors indistinct flake industries instead, there are some skulls however but poorly dated, so I guide my opinion on the very fast and basal diversification of mtDNA M especially).<br /><br />So nope: MSA tools can and even should mean Homo sapiens, not "archaics".Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-82907495886745570312023-10-29T19:24:07.789+01:002023-10-29T19:24:07.789+01:00Thanks for your input, Dvrmte.

Which study does actually confirm that Iwo Eleru was "archaic"?<br /><br />I'm aware of archaic "ghost" admixture in West-Central Africans, notably because Y-DNA A0 and especially A00, must be introgressions from that admixture event with closely related but pre-Sapiens populations of West Africa. However the frequencies are so rare that I wouldn't call that "large" admixture (although admittedly Neanderthal and Denisovan admixture, which is "small" and not "large" did not leave any haploid genetic in us other than maybe X-DNA lineage B006, this may be because Neanderthals and Denisovans were less close and thus less compatible with us than African archaics). <br /><br />I'm also aware of "ghost" admixture being reported in autosomal DNA, not just for West Africans but also for the East-Southern branch (in which no haploid DNA is detected however) but it always seemed to me as "small" and not "large" by any means.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-48928614299596752892023-10-28T16:19:01.013+02:002023-10-28T16:19:01.013+02:00According to DNA studies, Iwo Eleru was most likel...According to DNA studies, Iwo Eleru was most likely archaic, and modern West Africans, and sub-Saharan Africans in general, have relatively large amounts of archaic Ghost admixture from a species that split from the human line before Neanderthal. <br />There are Middle Stone Age sites in West Africa less than 11,000 years old, with stone tools normally associated with Erectus. <br />Modern West African only reached modern human status during the Holocene. The oldest modern human fossil with their phenotype is the 6,400 year old Asselar Man skeleton found in Mali.<br /><br />West Africans also have ancient Eurasian admixture. They also have Eurasian paternal haplogroups such as E1b1a and R1b-V88. West African archaic humans such as Iwo Eleru, became modern humans after Eurasian admixture which correlates with the appearance of modern humans in the region. dvrmtehttps://www.blogger.com/profile/15502430658857861684noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-24915922475395243882023-09-09T12:36:33.989+02:002023-09-09T12:36:33.989+02:0040 new ancient Canarian samples that are estimated...40 new ancient Canarian samples that are estimated to have lived from the 3rd to the 16th century were analyzed in this new paper from Serrano et al (2023), “The genomic history of the indigenous people of the Canary Islands.” As previously observed, the ancient Canarians are still very divergent from Paleolithic/Early Neolithic Moroccans, and cluster more closely with Late Neolithic Moroccans and present-day North African populations. <br /><br />However, all present-day Northwest Africans have less ancient North African, but a lot more West Asian & African ancestry compared to those ancient Canarian samples, and all of them are also very similar to one another (including Sahrawis). Sub-Saharan African ancestry was still detected in some of those ancient Canarian samples, suggesting the existence of trans-Saharan migrations in North Africa already before the Common Era. Moreover, those ancient Canarian samples seem to be divided in roughly 2 clusters. One located in the western islands that’s more closely related to Upper Paleolithic and Early Neolithic North Africans and the other in the eastern islands to European populations.<br /><br />https://www.nature.com/articles/s41467-023-40198-wThiernohttps://www.blogger.com/profile/13452118643827292940noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-68849554030987405462023-08-17T05:24:43.687+02:002023-08-17T05:24:43.687+02:00All E is African but E1b specifically also appears...All E is African but E1b specifically also appears to be native to Africa, NE Africa specifically and may be partly associated to the expansion of Afroasiatic languages (maybe also Nubian ones?), which parallels to a great extent that of E1b from what is now Ethiopia and the Sudans, with a major northern hub in Upper Egypt surely.<br /><br />Yes, Natufians were E1b but Natufian has also lots of African cultural influence and has been long argued in terms archaeological to be derived from African cultures/populations. No surprise here in the end.<br /><br />The overall picture may be a tad more complex but I'd say, based on what we know of archaeology and population genetics (both ancient and modern), that Palestine and Egypt were always very closely related and interacting since the very beginnings of the Upper Paleolithic. And that's even more noticeable in Y-DNA J1, which is most diverse in West Asia but is also extremely diverse in Egypt and NE Africa, with lineages criss-crossing from one continent to the other almost like fabric. J1 is surely a very ancient haplogroup and, as I understand it had Palestine and Egypt as main hubs (although its ultimate origins may be further north, as there's a lot of basal diversity in the Caucasus area).<br /><br />Another example is mtDNA haplogroup X, which has two branches: X1, almost exclusive of Egypt, and X2, centered in West Asia, with high diversity in Palestine and Iran and also a branch that must be early Upper Paleolithic to Native Americans, via Altai (and nope: the "Solutrean hypothesis" doesn't work because there was no X2 in Europe before the Neolithic).Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-70866896375208502112023-08-06T00:02:50.759+02:002023-08-06T00:02:50.759+02:00I wonder why you think that E1B is aboriginal Afri...I wonder why you think that E1B is aboriginal African when it's clearly comes from the Levant and is introduced into Africa. <br /><br />From wikipedia in the E1b haplogroup page:<br /><br />According to Lazaridis et al. (2016), Natufian skeletal remains from the ancient Levant predominantly carried the Y-DNA haplogroup E1b1b. Of the five Natufian specimens analysed for paternal lineages, three belonged to the E1b1b1b2(xE1b1b1b2a,E1b1b1b2b), E1b1(xE1b1a1,E1b1b1b1) and E1b1b1b2(xE1b1b1b2a,E1b1b1b2b) subclades (60%). Haplogroup E1b1b was also found at moderate frequencies among fossils from the ensuing Pre-Pottery Neolithic B culture, with the E1b1b1 and E1b1b1b2(xE1b1b1b2a,E1b1b1b2b) subclades observed in two of seven PPNB specimens (~29%). The scientists suggest that the Levantine early farmers may have spread southward into East Africa, bringing along Western Eurasian and Basal Eurasian ancestral components separate from that which would arrive later in North Africa.Blipblophttps://www.blogger.com/profile/03035845683958935507noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-38071094121867547162023-07-01T05:34:13.169+02:002023-07-01T05:34:13.169+02:00This new paper, “Northwest African Neolithic initi...This new paper, “Northwest African Neolithic initiated by migrants from Iberia and Levant” from Simões et al. (2023), shows that the Guanches from the Canary Islands are much more similar to Late and Middle Neolithic North Africans (KEB), than they are to Iberomaurusian/Taforalt, Epipaleolithic and Early Neolithic (KTG & IAM) North Africans. PCA analysis (Fig.1) also shows that the Guanches are shifted towards ancient Levantine populations. Interestingly, the Guanches’ ancestral components are also very similar to those of modern-day Northwest African samples that were used in this analysis: Saharawi and Mozabite populations from the Simons Genome Diversity Project (SGDP) dataset.<br /><br />All this information suggests that the ancestry of the Guanches, Saharawi people and other geographically similar Northwest African populations is unlikely to be different from other modern-day coastal Northwest Africans. <br /><br />https://www.nature.com/articles/s41586-023-06166-6#MOESM1Thiernohttps://www.blogger.com/profile/13452118643827292940noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-50102984210848461022023-04-16T17:05:27.261+02:002023-04-16T17:05:27.261+02:00The findings of this new paper called “Echoes from...The findings of this new paper called “Echoes from the last Green Sahara: whole genome analysis of Fulani, a key population to unveil the genetic evolutionary history of Africa,” contradict the hypothesis that the NW African component of Fulani is solely due to recent admixture between western African and northern African groups.<br />https://www.biorxiv.org/content/10.1101/2023.04.06.535569v1<br /><br />The so-called Muslim expansion south of the Sahara in historical times as the only explanation for the origin of Fulani people is not credible, especially considering these admixture, qpWave, qpAdm and older Y-DNA analyses. They reveal much more complex and ancient phenomena which may have been more widespread across the Sahara and Sahel than previously anticipated. The advantage of their analyses is that they used more than 1800 samples, including ancient DNA samples such as Iberomaurusians, from the relevant geographic regions and continents. This contrasts with other DNA studies about these populations, which were more limited both in scope and in sequencing depth & coverage. <br /><br />Some of the findings in this paper confirm what I had long suspected: that there could be some deeper & older underlying phenomena associated with the genetic origins of Fula people and similar groups across the Sahel that have been largely unexplored up to this point. This is in part why, in relation to the Puerto-Rican/Guanche connection with my data, I had limited myself by simply implying that it could suggest some complex genetic links with other Northwest African populations and didn’t mention recent historic Muslim expansion south of the Sahara as a hypothesis for disentangling the complex origins of Fulani people. At best, I considered it to be just anecdotal depending on each person’s ancestry.<br />Thiernohttps://www.blogger.com/profile/13452118643827292940noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-65915586116297187582023-04-03T18:20:04.289+02:002023-04-03T18:20:04.289+02:00I mean that but through the filter of North Africa...I mean that but through the filter of North Africa, i.e. North Africans, who are mostly Asian in terms genetic, also have some amounts of Tropical African or Aboriginal African genetics (notably Y-DNA E1b) and these made their way to West Asia and (secondarily) Europe. That's why even Hitler was E1b, an aboriginal African patrilineage that never took part in the "out of Africa" migration and only moved into the Levant probably in the Mesolithic (and from there would reach Europe in the Neolithic). <br /><br />A lesser more direct E1b (and thus some Aboriginal African overall genetics) exists in West Iberia, originated in NW Africa at some uncertain time (maybe Bronze Age) but it has a more restricted geography.

This is most obvious in the Y-DNA haplogroup E1b, one of whose major branches spread via Egypt to West Asia, and from there to Europe (already in the Neolithic). Another E1b impact, mediated by NW Africa in an unclear but surely pre-Muslim timeline, is very apparent in the Western third of Iberia. <br /><br />Additionally there is the issue of the so-called "Basal Eurasian" component in West Eurasians ancient and modern, which I'm persuaded that it is Aboriginal African and not the left-behind West Asian element that many imagine. It's very clearly not just Dinka-like but actually phylogenetic trees strongly suggest that it is proto-Dinka. <br /><br />Overall the West Eurasian impact in NE Africa and later also in NW Africa is quite overwhelming but it's not a one-sided story at all and African influence in West Eurasians in general is very clear as well. A key episode surely happened in Egypt, c. 50-40,000 years ago, when the "proto-Caucasoid" apopulation arrived in the region (better documented in Cyrenaica but Egypt was surely more central) and had matrilocal interactions with the natives. Why matrilocal? Because it already happened before (IMO) in NW India / Pakistan: in both cases the population (which was clearly expanding and not contracting) incorporated mostly male lineages: only those in India/Pakistan (not even a single mtDNA lineage apparently) but both in Egypt, however much more intensely Y-DNA ones again.<br /><br />So my conclusion is that the early West Eurasian population was matrilocal and not "racist" re. other Homo sapiens (although maybe re. Neanderthals, as no secondary Neanderthal admixture happened that left any legacy). In contrast, one of their branches, the proto-Amerinds, who first migrated to Altai and then eastwards through NE Asia to Alaska and the rest of America, show patrilocality (almost exclusively incorporating mtDNA lineages from East Asia, retaining the absolutely dominant West Eurasian Y-DNA haplogroup Q instead). This may be, I guess, an adaptation to Northern climate and scattered populations, and we see it again in the Finno-Ugric migration in the opposite direction at a later time.

We have to infer it from: (a) modern distribution of genetics (haploid and autosomal) and (b) ancient genetics from populations like Taforalt in Morocco, which show that "Iberomaurusian" or Oranian culture people were not at all derived from ancient Europeans (Iberians) but essentially from West Asians instead (via Egypt-Cyrenaica, as we know from the archaeological record). See: https://forwhattheywereweare.blogspot.com/2018/04/no-iberian-in-iberomaurusian.html<br /><br />There is also some important European element in NW Africa (and maybe even in Sudan, more research is needed but that Y-DNA I in several Sudanese pops. is extremely suspicious) but it's more recent: from the Neolithic and ultimately from West Asia in fact. The Cardium Pottery Neolithic people (with genetics like those of modern Sardinians approx.) did clearly cross into Morocco-plus after arriving to Iberia. While unclear at this point, it's a possible source of R1b-V88 as well, which in any case had surely a key hub in Sudan (Chadic peoples origin probably) and does in any case has an ultimate Asian root, as all R < P < K < ... < F lineages (we know that these went all the way to SE Asia and back westwards via North India and West/Central Asia, the exact details are more complicated to unravel but the migration of these "clans" are the most amazingly long distance of Paleolithic peoples, more so as the Native Americans are also included: Q1 < Q < P...) I clearly identify the westward migration of P1 (precursor of R and Q) as something pertaining to the "Neanderwars", i.e. the invasion of the "Neanderlands" (West Eurasia) by our kin some 50,000 years ago, which is coincident with the formation and spread of the Upper Paleolithic (mode 4 or stone blade tech) in that same region and also into NE Africa (where is often called "Late Stone Age" = LSA). <br /><br />We can go haplogroup by haplogroup but I already have a synthesis of what probably happened in Asia (and by extension Australia, Europe, NE Africa, and later also NW Africa, and America) here: https://forwhattheywereweare.blogspot.com/p/continuing-with-joint-series-in-spanish.html (it's a bit old and would benefit from some corner polisihing but in the essentials I stand for it).

At le...I didn't say that, I don't think so. At least in my reply to you above I clearly said that the "unmistakably West Eurasian" component is so small that it could well be just "noise". Remember that autosomal DNA analysis is stastical and thus there is some room for error, which can only be properly gauged by contrasting various analysis and taking due care of inputing the best possible dataset. It's an art, sorta. <br /><br />However I know from other data/studies that Horners (Kushitics included) have a significant West Eurasian ancestry, which is probably very ancient in the greatest part (IMO from the early Upper Paleolithic, which clearly impacted NE Africa in general from a West Asian source of proto-Caucasoid populations). This West Asian (or West Eurasian or Caucasoid) component, most apparent in haploid genetics such as Y-DNA J1 and T or mtDNA M1 and various R/N haplogroups, is also apparent in autosomal DNA when you look carefully at it... but has been admixed with aboriginal African components into a homogeneous regional blend that it's sometimes easy to miss and makes harder to gauge the "exact" apportion of each contribution.<br /><br />While I haven't worked on this issue myself (and only know of very little research on the matter by others), I believe that this (North Africa focused) analysis I made a decade ago is relevant and interesting: https://forwhattheywereweare.blogspot.com/2011/12/north-african-genetics-through-prism-of.html<br /><br />In the Admixture runs, we consistently see that Ethiopians appear as a mix of African Aboriginal (maybe 40%) and West Eurasian/North African (c. 60%)... until at K=10 their homogeneization of many millennia "pays up" by showing an Ethiopian or Horner specific component. <br /><br />A somewhat similar case of intercontinental admixture happens with the Fulani, however for what I know this admixture is much more recent and pertains to Muslim expansion south of the Sahara in historical times, more specifically to the formation of the Kingdom of Tekrur, which is at the origin of the Fula people. Their specific source of admixture is Sahrawi-like (Mauritanian are probably similar) and produced interesting info somewhat accidentally about the destiny of Guanche people (also close in terms genetic) of Canary Islands, who were quite apparently deported in large numbers to the Caribbean colonies (at the very least Puerto Rico).

Again sorry if it's a dumb question, I don't have much experience in this field.Blipblophttps://www.blogger.com/profile/03035845683958935507noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-58838712165251953302022-06-18T01:34:34.592+02:002022-06-18T01:34:34.592+02:00It just seems to say that a population very simila...It just seems to say that a population very similar to Kushitic speakers (Oromos and Somalis in the data set) was present as far south as Tanzania some 3000 years ago. The purple component seems native East African (although based on other analyses it could well be also a consolidated Afro-Asian admixture), the grey component is Sardinian-like, i.e. unmistakably West Eurasian. <br /><br />However this last is small enough in Luxmanda that it could be little more than noise and maybe we should consider this population as East African aboriginal with no or very little West Eurasian admixture.

From Egypt and such it would later (Late Upper Paleolithic and Epipaleolithic) spread to NW Africa (West of Cyrenaica), being therefore less diverse (founder effects). <br /><br />J2 on the other hand seems to have spread more recently but quite vigorously from an Upper Mesopotamia center. Unlike J1, it's quite common in Europe, where it surely spread with the Halafian-derived Pelasgo-Tyrsenian peoples, which would later bring it to Italy, where the Roman Empire spread it westward (West of the Alps it's clearly strongly associated to Roman settlement and Italian autosomal genetics, most importantly in Southern Iberia). <br /><br />In West Asia we see both lineages but J2 is stronger towards the North or the Highlands and J1 is stronger towards the South or Arabia Peninsula. <br /><br />In North Africa (and also in the Horn), J2 is a marker of Semitic or Italian (Roman) influx, be it Arab, Phoenician or Jewish. It's not an "aboriginal" lineage in Africa, while J1 can be considered as such instead (certainly Paleolithic). <br /><br />Not all Y-DNA J is the same.
