Probably it has been differentiated there, and there is an Assyrian/Iranian etc. clade different from the Egyptian one. But your clades are anyway derived. The Ancestor clade is HV4 and I think have demonstrated on Worldfamilies that, even though there is an Assyrian (Humanist), the Italian samples are more ancient and at the origin. The other more ancient are the Russian ones: then this haplogroup was born in Europe, either Eastern or Western one. Malyarchuk has demonstrated that many Western European haplogroups peopled Eastern Europe about 15,000 years ago and HV4 could be one of them.Gioiellohttps://www.blogger.com/profile/13578860964923773647noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-9339280089329916212011-01-14T11:32:30.112+01:002011-01-14T11:32:30.112+01:00The Jordanian HV4a2 and I, unlike the Egyptian, ap...The Jordanian HV4a2 and I, unlike the Egyptian, appear to share transitions at 16287 and 16311 as well.

People don't drop their languages because they're bored and want to try something new".<br /><br />Obviously Arabic was imposed on the conquered peoples and consolidated via Islam. The same happened with Latin and so on.<br /><br />Nobody denies that there was a socio-political change with Islam in North Africa, what I reject is any major colonization from West Asia or Egypt at that point. But the "Arabs" from some point on are more likely to be descendants of Vandals, Romans and Carthaginians (along with, of course, some denationalized Berbers themselves and a few drops of genuine immigrant soldiers and top administrators). It is these cosmopolitan, often urban groups, which quickly assimilate in the new order, while the rural, mountain, ones often retained a Berber identity instead. <br /><br />"The Garcia paper states right at the start that the LGM "almost depopulated central and northern areas of Europe.""<br /><br />That is not what they conclude or can be concluded from mtDNA diversity: they reject recolonization from the SW and instead continuity in most lineages seems dominant. "Almost" is anyhow not the same as "totally". And I doubt Central-North Europe would retain such a high apparent diversity for all lineages if it was depopulated in any radical way. What the paper seems to support for most lineages is a Central European origin, which can only be understood in the context of European colonization. <br /><br />This has been my main model since I discovered the super-star of mtDNA H, but I did not expect this to extend so radically to almost all clades. However, if H1, H3, H4, H7 and V were to be in South Iberia in the LGM, so they could jump to North Africa, it is obvious they had to be consolidated by then and not to be signatures of "post-glacial expansion". So yeah, we need more depth in the analysis of H1 and the other many H subclades, as well as U5, V, etc. if we are going to clarify if there is any mtDNA signal of such glacial re-expansion or if this is restricted to Y-DNA (male biased migration like in North Africa - but less exaggerated maybe).Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-34923237649692256682011-01-13T03:20:16.051+01:002011-01-13T03:20:16.051+01:00@Wagg: good point, because that's pretty much ...@Wagg: good point, because that's pretty much the heart of Lappland precisely. <br /><br />...<br /><br />@Andrew:<br /><br />"My assumption was that once upon a time there were ethnically homogeneous Berbers, but that this changed with Iberian admixture. After that point in time you have Northwest African Berbers (call them proto-Moroccans and proto-Algerians if you will) who have significant Iberian DNA, and "near Egyptian" Berbers (call them proto-Tunsians and proto-Libyans and proto-West Egyptians perhaps) who don't. It may be a gradual cline that is significant simply because the distances are so great in the region, or it may be due to a clear divide caused by the Atlas Moutains, the result is the same either way".<br /><br />That does make sense, and probably reflects what happened in Capsian times. But has nothing to do with Islam or Romans, not that I can see. If it has anything to do with the introduction of camel, I'd like to see a relevant paper or at least a recount of relevant archaeological evidence (nothing so far). I'd imagine that horse was introduced from the West in Chalcolithic times or Bronze Age the latest anyhow.<br /><br />But is anyhow a much more beautiful model than just vagenesses: Capsian would in this model be just the beginning of a more or less sustained East to West flow that gradually reduced the European ancestry, specially in the Y-DNA side. I can tentatively agree with that, however let's not forget that Morocco, Algeria(coasts) and Tunisia (coasts) can harbor much larger populations than all Lybia can. This is a major issue when one posits that a tiny nomadic group from a semi-desert area replaced a huge sedentary group, like Turkmens "colonizing" Anatolia (what obviously never happened but in minimal amounts). <br /><br />In general the more clear archaeological evidence of an East to West flow is Capsian culture (from Nubia rather tan Lybia), however what you say makes some sense as reinforcement of this process. Much as Metal Ages Mediterranean flows surely reinforced (in some cases dramatically I understand) the early Neolithic colonizations. Yet these are the ones which made most of the impact probably.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-19351206363817851932011-01-13T00:19:46.204+01:002011-01-13T00:19:46.204+01:00it's not like the northern areas really got de...<i>it's not like the northern areas really got depopulated.</i><br /><br />The Garcia paper states right at the start that the LGM "almost depopulated central and northern areas of Europe."Andrew Oh-Willekehttps://www.blogger.com/profile/02537151821869153861noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-77088115779590997182011-01-13T00:17:04.892+01:002011-01-13T00:17:04.892+01:00"The main problem seems obvious: the camel ar..."The main problem seems obvious: the camel arrived happened via Egypt and was spread by the pre-existent Berbers: the arrival of the camel supposes no apparent change, maybe economical but not linguistic or ethnic (except maybe in the Sahara but that's a very specific place with very low density and peculiar peoples). <br /><br />The other main problem is that there is no meaningful Arabian Y-DNA in North Africa"<br /><br />My conjecture was, intentionally, more narrowly phrased than you are reading it, because I am aware that there isn't much Arabian Y-DNA in North Africa and don't have evidence of Berbers being replaced by ethnically non-Berbers. Instead, I specificly refrained from suggesting that it was the Arabs themselves who demically brought the profound cultural changes that Islamization brought about, or there was replacement of North African populations by non-North Africans.<br /><br />My assumption was that once upon a time there were ethnically homogeneous Berbers, but that this changed with Iberian admixture. After that point in time you have Northwest African Berbers (call them proto-Moroccans and proto-Algerians if you will) who have significant Iberian DNA, and "near Egyptian" Berbers (call them proto-Tunsians and proto-Libyans and proto-West Egyptians perhaps) who don't. It may be a gradual cline that is significant simply because the distances are so great in the region, or it may be due to a clear divide caused by the Atlas Moutains, the result is the same either way.<br /><br />The "near Egyptian" Berbers get camels, horses, Islam, and who knows what else, in multiple waves of new technology via Egypt (mostly early Neolithic and Islamic respectively, but possibly other waves in between as well), make their way West and with their newly superior technology displace the Iberian admixed Berber men with Berber men who aren't very Iberian admixed. Power is sexy and technology confers survival advantages for the whole family. Voila! A lower proportion of European Y-DNA in North Africa. <br /><br />Intra-ethic conflict of this kind by the first to get new technology has been seen in modern times, for example, in the New Zealand Wars in which some Maori tribes with guns ravaged those that lacked them.<br /><br />There is a fundamental flaw with this scenario only if there is no population genetic cline from West to East in North Africa among Berbers, and this seems unlikely, particularly in the pre-camel, pre-horse, pre-domesticated animal era. In that era one would expect far more localized gene pools than existed once riding animals appeared.<br /><br />I have good company in thinking that the camel and domesticated animals had a profound cultural impact and confer great selective advantage. <br /><br />It so happens that I personally think that it is more likely that there was linguistic shift to Berber from a non-Afro-Asiatic language around the time that the camel arrived in Berber history (although probably not much demic replacement, because North Africa may not have been too attractive as a place for newcomers to settle at the time). But, that doesn't have much relevance to the population genetic effect of that kind of scenario. <br /><br />It is beyond dispute, of course, that there was significant linguistic shift in connection with Islamization - and linguistic shift basically never happens without other significant cultural or political changes as well.

The arrival of camels and then of horses and associated Berber and then Muslim technological and cultural influences would provide a perfect situation for North African and/or Middle Eastern men from outside the area of Iberian genetic influence to sweep in and displace local men in the influenced area, much as the Indo-Europeans, Turks, Mongols and Yaoyi did in much of Eurasia and Japan.Andrew Oh-Willekehttps://www.blogger.com/profile/02537151821869153861noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-58673412367720872422011-01-12T01:42:32.791+01:002011-01-12T01:42:32.791+01:00Forgot:

I have already directed you in the past to Bocquet-Appel 2007, which is just one of many papers and books that could tell you that the Franco-Cantabrian region was densely populated all the time, including the LGM. Also in general greatest diversity is to Central Europe, which is above 45 degrees (the latitude of Dordogne). <br /><br />More real is that there was never a total depopulation of Central Europe and that at least part of the lineages present today have been there since Aurignacian or Gravettian times. <br /><br />"LGM refugees in Western Europe went as far South as they possibly could because every place else was too damn cold".<br /><br />This may explain Gravettian expansion, specially in Iberia proper. As you may know, Gravettian in SW Europe is a late arrival (like 22 Ka, while in Central Europe and Italy is like 28 Ka) and almost overlaps with Solutrean, which seems a reaction against this techno-culture, often described as "intrusive" in the Franco-Cantabrian region. In Iberia proper, however, Gravettian made a very strong impact (Aurignacian colonization was sparse) and recycled Solutrean that here is the "intrusive" element into a quite unique Gravetto-Solutrean. <br /><br />But it's not like the northern areas really got depopulated, certainly not the FC region nor Moravia (where the evidence is clear) and I'd dare say that other pockets must have persisted, re-expanding when climate improved. It's damn cold in Lapland but people live there anyhow (and they would be able with UP tech as well). Where they do not live is (only) in glaciated areas, such as Central Greenland. This ice cap extended then to Central-South England, Denmark, Mecklemburg, most of Poland, etc. So it's reasonable to think that some people lived in the Netherlands or even the southern coasts of England and Doggerland, even if we lack evidence today. <br /><br />There are even theories that propose that Aurignacian survived over there (some evidence seems to exist, though not sure how much or how good) and this influenced the Aurignacian renaissance we call Magdalenian. <br /><br />In this sense we might argue that the blue and red clusters might represent Gravettian and Aurignacian waves respectively. It sounds better than "Celtic" to my ears, certainly. But it is just an speculation so far. <br /><br />"The study also seems to support more gene flow from Iberia to North Africa than in the other direction".<br /><br />That is what I think as well. However the characteristic Y-DNA of those contacts seems to have receded in North Africa more than in Europe. I'd expect that 30% European (H and V) mtDNA in North Africa should correlate with at least 30% European Y-DNA once. But today it is little more than 5% (albeit 17% in Guanche mummies). Instead E1b1 in Europe is in good apportion with what can be considered North African mtDNA (U6 and L(xM,N)). <br /><br />So Capsian culture in North Africa must have implied some sort of male-biased replacement but I can't detect anything of the like in Europe instead.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-1510045781327277812011-01-12T01:20:05.286+01:002011-01-12T01:20:05.286+01:00@Andrew:

The clusters are not too relevant anyhow: they are weak (fuzzy). Also I'd expect more Celtic-specific genetic input in England than in Ireland or Scotland, honestly. One thing is what language you keep today and another thing is where the Celts arrived first and most likely made the greatest impact. Similarly in France, I'd expect more "Celtic blood" in the North than in the South, etc. <br /><br />"The red clusters show something of an affinity for areas Germanic influences, either linguistically, or via Atlantic Viking raids, although this also has problems since Viking raids should create Y-DNA rather than mtDNA clusters".<br /><br />Yes, it's very fuzzy. If anything, the Red cluster seems to mean greater H (and maybe greater U as well). Arduous confirmation would be needed but that's my impression so far. <br /><br />It is possible that they simply indicate greater/lesser Neolithic impact or, alternatively/complementarily two somewhat distinct (but related) waves or vectors in the European colonization as such.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-49867694399580977192011-01-12T01:11:57.737+01:002011-01-12T01:11:57.737+01:00@Gioello: I can't really discuss HV4a.

The paper proposes a Western (Cantabrian strip) origin for HV4a1 and seems to accept an Eastern one for the rest HV4, including HV4a2, only reported in Egypt and Jordan in this paper. That's all I can say, and being a minor lineage, I imagine that the subject remains open. <br /><br />The case looks somewhat similar to that of that U8 anyhow, which, as you know, has a Basque sublineage and then U8b'K which has greater likelihood of Eastern Mediterranean origins and an Italian connection. It's difficult to say, really, and maybe best is just to understand them as part of the colonization of Europe, with ultimate origins in West Asia in all variant theories.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-67291890783332379252011-01-12T01:05:29.899+01:002011-01-12T01:05:29.899+01:00@Ken:
